The copy-paste afternoon
“Change the name, export, repeat — 300 times.”
With Zandovi: Bind the fields that change to {{variables}} and let a CSV do the repeating. One batch job returns all 300 finished designs as a ZIP — minutes, not an afternoon.

What is Zandovi?
Zandovi is a template-based image and PDF generation API with a full visual
design editor. You design a template once on a canvas, bind the parts that
change — text, images, QR codes, barcodes — to {{variables}}, then
render personalized copies of it: one at a time by posting JSON to the REST API, or a
few hundred at once as a batch job, fed by a CSV in the app or a rows array from your
own code, that hands back a ZIP.
It is built for the jobs where one design has to become many files — event badges, certificates, gift cards, coupons, tickets, Open Graph images, localized social posts. Output is PNG, JPEG, WebP or print-ready PDF up to 4096×4096 pixels, from 200+ starter templates across 18 categories. There is a free plan and it includes the full API.
-
Not a prompt-to-image model
Zandovi does not invent a new picture each time. You draw the design once; every render is that design with different data in it, pixel-identical everywhere else.
-
Not a headless browser
No Chrome to keep alive, no HTML-to-PNG screenshotting. A Skia renderer draws the template server-side and streams the file back.
-
Not developer-only
The same template is editable on a visual canvas. Designers and ops maintain it; engineers only ever send the JSON.
One design, forty listings
A listing flyer gets four text variables, a photo variable and a QR code. The CSV template comes back with exactly those columns. Forty rows go up, forty finished flyers come down as one ZIP, and the same template then renders from a single HTTP call.
Nothing is requested from YouTube until you press play. Watch on YouTube instead.
Personalized designs shouldn’t be manual work.
If any of these sound familiar, Zandovi was built for you — same design, same data, none of the repetition.
The designer bottleneck
“Every asset waits on the one person with the source file.”
With Zandovi: Brand-locked templates let teammates change the data, never the design. Names, prices and photos rotate — layout, fonts and logo stay untouched.
The DIY rendering stack
“We run a headless browser just to make PNGs.”
With Zandovi: One POST with JSON returns a rendered PNG, JPEG, WebP or print-ready PDF up to 4K. No browser fleet, no SDK, nothing to maintain.
Image generation API
One POST. One image — or four hundred.
A template-based image generation API. No headless browser, no SDK to install — a Skia-based, server-side renderer returns PNG, JPEG, WebP, or print-ready PDF up to 4096 × 4096 px at 300 DPI.
- Per-organization API keys with usage tracking
- Batch jobs — POST one template plus up to 400 rows, then poll or be called back, and download a ZIP
- Signed completion callbacks — give a job a callbackUrl and it posts you a summary when it ends, HMAC-signed and retried, with the delivery status readable on the job
- Idempotency keys on batch submits — a retried request is never billed or rendered twice, and cancelling refunds every unrendered row
- Schema introspection — describe variables before sending
- Sub-second renders at 1080p with Redis caching
- Bytes by default, or a hosted URL on request — the link comes back with its exact expiry, and a revoke endpoint on every plan

Frequently asked.
Everything you'd want to know before trying Zandovi.
How does batch generation work?
Design a template with variables using {{name}} syntax, then submit your data — upload a CSV in the app, or POST a rows array to /api/v1/batch-jobs from your backend. Zandovi generates a personalized export per row and hands back a ZIP. Poll the job, or give it a callbackUrl and be told when it finishes.
What export formats are supported?
PNG, JPEG, WebP and PDF at up to 4096×4096 px with full quality control. Every format takes a 1–4× scale multiplier for print-ready output.
Is there an API?
Yes. Public API keys let you generate designs server-side from any language — one POST for a single image, or a batch job for a whole set. Perfect for sending personalized email graphics, order confirmations, or dynamic social images.
Can I get a URL instead of a file?
Yes. Click Share on any render in the editor, or add delivery: "link" to an API call, and you get a public URL for the image — no bucket, no CDN, no cleanup job to build. Ideal for <img> tags in transactional email and for automation tools that handle JSON more comfortably than binary.
How long do share links last?
Every link carries an expiry set by your plan — seven days on Free, thirty on Personal, up to a hundred and eighty on Business. When it lapses the image is deleted and the URL stops resolving. You can revoke a link earlier at any time, and anyone holding the URL can open it until you do — treat them as unguessable, not private.
How do teams and organizations work?
Invite teammates to a shared organization. Control member roles, share templates and projects across the team, and scope billing per org. Each user can belong to multiple organizations.
What about QR codes and barcodes?
Both are first-class citizens. Drop a QR or barcode element onto any template, bind it to a variable, and every generated design gets its own scannable code.

What is Zandovi?
Zandovi is a web-based design platform that combines a full visual editor with variable placeholders ({{name}} syntax) and batch generation. You design a template once, then generate hundreds or thousands of personalized images — from a spreadsheet in the app, or from your own backend over the REST API.
Who is Zandovi for?
Marketing and ops teams making personalized graphics at scale, developers integrating dynamic images into their products, small businesses creating menu cards, gift cards and coupons, and event organizers producing badges, certificates and tickets.
How do I sign up?
Create a free account at https://app.zandovi.com. You can sign up with email, Google OAuth, or a WebAuthn/FIDO2 passkey. No credit card is required.
Is there a free plan?
Yes. The Free plan includes 100 renders per month, one project with five templates, 25 batch rows per job, the full API, and every export format including print-ready PDF at 300 DPI up to A5. No credit card is required.
What does Zandovi cost?
Free is $0 forever. Paid plans start at $29/mo for Personal (5,000 renders), then Studio $49/mo, Team $79/mo and Business $199/mo. Annual billing is 2 months free — pay for 10 months, get 12. Prices exclude VAT / sales tax.
Visual editor Drawing tools, canvas controls, and the editor UX.
What drawing tools does the editor have?
Rectangle, circle, ellipse, line, arrow, star, polygon (variable sides), triangle, curved rectangle, text, image, hand/pan, freehand draw, QR code and barcode. Each tool has its own configuration panel.
What canvas sizes are supported?
Any custom width × height in pixels. Built-in presets cover business cards (US and EU), gift cards (regular and large), coupons, tickets, social-media formats and A-series paper sizes.
Can I zoom in and out on the canvas?
Yes — zoom from 10% up to 400% with pan/scroll navigation. There is also a grid overlay with configurable snap-to-grid spacing, ruler display on the top and left edges, and smart vertical/horizontal alignment guides shown while dragging.
How many undo steps does Zandovi support?
The editor keeps 50 steps of undo/redo history for every canvas operation.
Can I change the canvas background?
Yes. Backgrounds can be a solid color, a linear gradient, a radial gradient, or an image fill. The gradient editor supports multiple color stops and configurable start/end points.
Does Zandovi support dark mode?
Yes, the editor and the marketing site both support a dark theme. Your preference is stored locally.
Are there keyboard shortcuts?
Every tool has a single-key activator: V (select), R (rect), O (circle), E (ellipse), L (line), A (arrow), S (star), P (polygon), G (group), U (curved rect), T (text), I (image), H (hand), D (draw), Q (QR), B (barcode). Plus Cmd/Ctrl+Z for undo, Cmd/Ctrl+Shift+Z for redo, Cmd/Ctrl+A to select all, Cmd/Ctrl+D to duplicate, Cmd/Ctrl+C/V for copy/paste, and Delete/Backspace to remove the selection.
Text & fonts Typography controls and font handling.
How many fonts are included?
Zandovi ships with 47 Google Fonts preloaded at service startup for consistent rendering — 10 sans-serif, 9 serif, 10 display, 15 handwriting and 3 monospace families.
What text properties can I control?
Font family, size, weight, italic style, color, decoration (underline, line-through), horizontal and vertical alignment, line height, letter spacing, word wrap mode (word, character, none), overflow handling (clip, ellipsis, visible) with a custom ellipsis character, and per-side or uniform padding.
Does text auto-fit to its container?
Yes. Auto-fit text scales to its container with configurable minimum and maximum font-size bounds.
Variables & placeholders Binding data to elements with {{variables}}.
How do variables work?
Wrap any text in {{double_braces}} to make it dynamic. The placeholder is replaced with your data at render time — either from a CSV row, an API request body, or a default value you set in the editor.
What variable types are supported?
Text, number, date, email, URL and phone. Each can have a human-readable label, a description, a required/optional flag, a default value, and validation rules (min/max length, regex pattern, allowed options).
Can I bind a variable to an image?
Yes. Image placeholder elements get replaced with a different image at render time, so you can rotate product photos, member portraits or screenshots per row.
Can QR codes and barcodes be variable?
Yes — both bind to a variable, so every generated design carries its own scannable code. Useful for ticket QRs, attendee badges and personalised links.
Can I see what variables a template uses without opening it?
Yes. Each template exposes a JSON schema describing its variables, types and validation rules. There is also a project-level merged schema that combines variables across every template in a project.
Images Uploading, editing and reusing images.
How do I add an image to a template?
Drag-and-drop an image onto the canvas, or search built-in stock libraries (Unsplash, Pexels and Pixabay) without leaving the editor.
Can I edit an image after I drop it in?
Yes. Crop with X/Y/width/height parameters, apply filters (brightness, contrast, saturation, blur, grayscale, sepia), round the corners, and choose an object-fit mode (contain, cover, fill, none).
What image formats are accepted?
Common web formats. Per-template image validation rules can restrict allowed formats, min/max dimensions, aspect ratio and maximum file size.
Do uploaded images get tracked?
Yes. Image usage tracking shows which templates reference each uploaded image, and deletions are blocked (409 Conflict) if the image is still in use.
Can I reference an image across templates?
Yes. Zandovi uses a portable zandovi:// URL scheme so the same image can be referenced from multiple templates without duplicating the file.
Batch generation Going from one template to thousands of outputs.
How does batch generation work?
Design a template with variables, then give Zandovi one row per output and one column per variable — as a CSV uploaded in the app, or as a rows array posted to the batch API. Zandovi renders a personalized export per row and hands the result back as a ZIP.
Can I run a batch from code instead of the app?
Yes. POST /api/v1/batch-jobs takes one template plus a rows array, validates every row before anything is billed, and returns a job ID. Poll GET /api/v1/batch-jobs/{jobId}, or supply a callbackUrl and be told when the job reaches a terminal state. Same renderer as the CSV tab, no spreadsheet in the middle.
How many rows can I render in one batch?
25 rows per job on the Free plan, rising by tier up to 400 rows per job on Business. One template per job, and two jobs can be active at a time.
What happens to a row that fails?
The job carries on and the failure is recorded against that row. GET /api/v1/batch-jobs/{jobId}/items lists every submitted row in order with the file it produced and the error if it has one, so a failure traces back to the data that caused it. Failed renders are refunded.
How fast is the batch renderer?
It depends on the number of outputs and the complexity of the template. Moderately complex templates without external images to download typically render in about 50 seconds.
Output & rendering How the rendered images come out.
What export formats are supported?
PNG (lossless), JPEG (lossy), WebP, and print-ready PDF. Lossy formats accept a quality parameter from 1 to 100.
What is the maximum output resolution?
Up to 4096 × 4096 pixels per image, with a scale multiplier of 1–4×. The API's outputDpi option accepts 96, 150, 300 dpi; the editor's own export dialog covers a wider 72–600 dpi band.
How is rendering done server-side?
The renderer is Skia-based via @napi-rs/canvas, so no headless browser is involved. It runs the same drawing primitives the editor uses — shapes, text, images, QR codes, barcodes, gradients and groups.
Can I get a print-ready PDF?
Yes. PDF can be rendered up to 300 DPI with the defined physical size.
Developer API Generating images programmatically.
Is there a public API?
Yes. Per-organization API keys authenticate requests via the X-Api-Key header. The API exposes endpoints to generate a single image, submit and manage batch jobs, and introspect the variable schema of a template or project.
How do I call the generate endpoint?
POST to /api/v1/templates/{id}/generate with a JSON body containing variables and options (format, outputDpi, quality). The response streams the rendered image binary, or a base64-encoded JSON payload if you prefer.
Can I be notified when a batch job finishes?
Yes. Add a callbackUrl to the submission and Zandovi POSTs a completion summary — job ID, terminal status, final counters — to that https URL when the job ends. Every delivery is signed with an X-Zandovi-Signature HMAC using a per-organization secret that is separate from your API key, delivery is at-least-once with a stable deliveryId to deduplicate on, and whether it landed is readable on the job itself.
How long are batch results kept?
A finished job's ZIP is retained for 30 days, and each download link is valid for an hour — request a fresh one whenever you need it. After 30 days the archive is deleted and the download reports itself as expired, while the job, its counters and its per-row outcomes stay readable.
Is the API rate-limited?
Yes. Limits are enforced per-organization using Redis-backed distributed rate limiting. Batch submissions and status reads sit in separate tiers, so polling a job never competes with submitting one. Paid plans have higher quotas.
Where can I find SDK code samples?
The API is a plain REST endpoint — you can call it with curl, fetch, requests, or any HTTP client. cURL examples are in the developer section of this page.
Templates & projects Saving, organising and sharing your work.
How many templates ship with Zandovi?
200+ templates across 18 categories: gift cards, coupons, certificates, business cards, tickets, social-media posts, birthday cards and more. Edit any of them, save your own variants, and share them with your team.
Can I have multiple templates in one project?
Yes. Projects group related templates with tabbed navigation, thumbnail previews, drag-to-reorder, and per-template visibility (private or shared).
Can I copy a template to another project?
Yes. Templates can be copied between projects, and entire projects can be cloned with all of their templates duplicated.
QR codes & barcodes Scannable codes baked into your designs.
What QR code options are supported?
QR codes have configurable error-correction levels, custom colours, an optional logo overlay, and configurable margin. Bind them to a variable for dynamic content.
Which barcode formats are supported?
CODE128, EAN-13, UPC, CODE39 and ITF-14. Each can be bound to a variable for dynamic values.
Can codes be different per row in a batch?
Yes — that is the main use case. Bind the code to a variable and every rendered output gets its own scannable code derived from the CSV row.
Teams & organizations Working with teammates and managing access.
How do teams work?
On sign-up, each user gets a personal organization automatically. You can create additional team organizations, invite teammates by email, and switch between organizations from the workspace picker.
What member roles are available?
OWNER (full control + billing), ADMIN (manage members + templates), and MEMBER (use templates, contribute designs).
Can I transfer ownership of an organization?

Use cases Things real teams are using Zandovi for.
Personalized social-media graphics for marketing campaigns
Marketing teams upload a CSV of customer names, segment tags and offer codes, bind them to a brand-locked template, and generate up to 400 personalized social posts in one job. Each post is on-brand because the template is locked — only the variable values change. Outputs feed straight into the scheduling tool of choice.
Bulk event badges with attendee QR codes
Event organisers upload an attendee CSV with name, company, ticket type and a unique attendee ID. The template binds the name and company to text variables and the QR code to the attendee ID. Zandovi renders up to 400 badges in a single ZIP, ready for the print shop.
Course completion certificates at scale
Education platforms generate course-completion certificates by feeding student name, course title, completion date and a verification URL into a certificate template. Output is a print-ready PDF per student at 300 DPI with embedded fonts.
Gift cards and coupons for retail
Retail brands design one gift card template, then issue up to 400 unique cards with personalized recipient names, gift amounts and unique barcode codes — generated from a CSV and emailed to recipients in a single batch.
Dynamic menu cards for restaurants
Restaurants build a single menu-card template (dish name, ingredients, price, restaurant name), then re-generate the whole menu whenever prices change. One CSV update reprints the entire menu without touching the design.
Personalized email graphics from a backend
Developers call the public API from their backend to render a personalized hero image for every transactional email — including the recipient name, order number, and a QR code linking to the order receipt. Each render is under a second at 1080p.
Localized social posts for multiple regions
Global marketing teams maintain one template per format, and render localized variants — translated copy, regional currency, locale-specific imagery — by switching out variables per market. One source design, dozens of localized outputs.
Conference tickets with scannable barcodes
Conferences generate uniquely numbered tickets — each with a CODE128 barcode tied to a ticket ID — and email them as PDF attachments straight from their booking system via the Zandovi API.
Real-estate listing flyers
Real-estate agencies bind listing photo, price, address, agent name and a QR code linking to the full listing into a flyer template. New listings produce a new printable flyer in seconds with no manual design work.
Open Graph images for blog posts
Blogs generate per-post OG images automatically: the post title, author and tag are bound to variables, and the build pipeline calls the API to render a unique 1200×630 image for every article URL.
Membership cards for clubs and gyms
Clubs design a membership card with member name, photo, tier and a QR code tied to the member ID. A nightly batch keeps every card collection up to date.
Birthday and anniversary cards for CRM workflows
CRM platforms call the API on a customer's birthday or anniversary to render a personalized greeting image, attach it to the outgoing email, and ship it — fully automated.
