The canvas
Place it, then hand it to the API
Text, images, shapes, frames, and groups on a multi-page canvas. Name a layer and it becomes an override key. Everything you did not name stays locked.
Template to PNG, JPG, WebP, AVIF, or PDF
Stop exporting the same image by hand
Draw the template once. Name the layers that change. Send JSON. Get PNG or PDF in a few seconds.
25 free images, then 1,000 / mo from $29
Examples
One template. Every record.
Same layout each time. Only the words and photos in the request changed.
The pictures you still make by hand
Name what changes. Send a short list. Get a file back.
How it works
Draw. Name. Send the fields.
You do the first two once. The third is what your app or agent does after that.
- 1
Draw the template
Text, images, shapes, and charts on a canvas. Or start from a design you already have.
- 2
Name the layers that change
A named layer becomes a key in the request. Everything else stays locked. Pin a version so a live render does not break when you edit.
- 3
Send the changing fields
Post the names, photos, and prices. A few seconds later you get a URL to a PNG, JPG, WebP, AVIF, or PDF.
Design
Edit the canvas. Pin production.
Keep editing like any other design tool. Live renders stay on the version you approved until you publish a new one.
Charts
Send an array, get it drawn
Eight chart types: bar, horizontal bar, line, area, pie, donut, radar, and radial. Up to 500 rows and 8 series. Data, series, and chart type are overridable per render.
QR and barcodes
Codes, generated at render time
QR, Code 128, EAN-13, and Code 39. Pass the value in the request. Toggle the human-readable text. Drop a logo in the middle of a QR.
Repeat groups
One JSON row becomes one card
Mark a group as a repeat template and bind an array. A hundred items render as a hundred instances. The canvas grows to fit.
Automate
One POST. Five formats.
Send the layers that change. Get a file URL. You do not run Chromium.
Render
Template id, format, and the layers that changed
The response is a URL to a finished file. PNG, JPG, WebP, AVIF, or a multi-page PDF from the same template, up to 3×, with transparency on PNG, WebP, and AVIF. Wait, stream, poll, or take a signed webhook — same job.
Batch
Queue fifty, walk away
One request queues up to 50 renders and returns a batch id. Poll the batch, or let each job hit your webhook when it finishes.
Schema
Ask the template what it accepts
GET the schema and you get every overridable layer and its type. Enough to build a form, validate input, or let an agent fill it without guessing.
