Frequently asked.
Everything you'd want to know before trying Zandovi.
How does batch generation work?
Design a template with variables using {{name}} syntax, upload a CSV with your data, and Zandovi generates a personalized export per row. Download everything as a ZIP.
What export formats are supported?
PNG, JPEG, WebP and PDF at up to 4096×4096 px with full quality control. Each format supports scale multipliers for print-ready output.
Is there an API?
Yes. Public API keys let you generate designs server-side from any language. Perfect for sending personalized email graphics, order confirmations, or dynamic social images.
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.
Everything about Zandovi, in one place.
A categorized reference covering features, use cases, the API, billing and teams. Expand a category to read the detail.
Getting started The basics of Zandovi.
What is Zandovi?
Zandovi is a web-based design platform that combines a full visual editor with variable placeholders ({{name}} syntax) and CSV-driven batch generation. You design a template once, then generate hundreds or thousands of personalized images from a spreadsheet or via the 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?
Zandovi is in private beta. Join the waitlist with your email — invites usually go out within a few days. Once invited, you can sign up with email + password, Google OAuth, or a WebAuthn/FIDO2 passkey.
Is there a free plan?
Yes. The Free plan includes one workspace, five templates, and PNG export up to 1080p. No credit card is required to use it.
What does Zandovi cost?
Pricing will be announced before the public launch. Join the waitlist to be notified first.
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 48+ Google Fonts preloaded at service startup for consistent rendering — sans-serif, serif, display, handwriting, and monospace families are all represented.
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, upload a CSV with one row per output and one column per variable, and Zandovi renders a personalized export per row. Download the result as a ZIP.
How many rows can I render in one batch?
Up to 100 rows per job by default. Higher caps are available on Team plans.
How fast is the 100 rows 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× to 3×. DPI presets cover 72, 96, 150, 300 dpi for both screen and print intents.
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, trigger a project-level batch, 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.
Does the API support idempotency?
Yes. Pass an Idempotency-Key header to safely retry a request without producing duplicate renders or duplicate billing events.
Is the API rate-limited?
Yes. Limits are enforced per-organization using Redis-backed distributed rate limiting. Pro and Team 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?
Yes. Ownership can be transferred to another OWNER or ADMIN, and members can be removed at any time.
Is single sign-on (SSO) supported?
SSO is planned for the Enterprise plan.
How are invitations handled?
Invitations are emailed with a token that has a configurable expiry. Pending invitations can be listed, resent or revoked.
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 1,000+ 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 1,200 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 500 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.
