# Turn your templates into PDFs with one API call.

Design an invoice, certificate or report once. Send the data, get back a vector PDF with text you can select. Long content flows onto as many pages as it needs.

*Nine files from three campaigns in English, French and Spanish: rendered as PDFs, one API request per ad, then downloaded together as one ZIP.*

## How it works

1. ### Design the document
   Lay it out in the browser editor or start from a gallery template. Mark names, dates, line items and totals as variables.
2. ### Send the data
   Call the render endpoint with format pdf and your values. Or send up to 500 rows in one bulk request and get one PDF per row.
3. ### Get the PDF
   You get a hosted link and the page count back. Fonts are embedded, so the file looks the same on every device.

## Start from a real template

- [InvoicesLine items that flow onto the next page when they need to.](https://bannx.com/templates/calculated-invoice-a4)
- [CertificatesOne per attendee, from your sign-up list.](https://bannx.com/templates/workshop-completion-landscape-certificate)
- [Shipping labels4 × 6 labels filled in from each order.](https://bannx.com/templates/shipping-label-4x6)
- [Listing flyersAn A4 feature sheet for each property.](https://bannx.com/templates/property-feature-sheet-a4)

## What it costs

25 free renders every month. Starter is $15 a month for 1,000 credits. An image costs 1 credit, a video clip 5 credits.

A PDF costs 1 credit per page, so a 3-page invoice costs 3. Renders stop with a clear error, never an overage bill. Credit packs start at $9 for 500 credits.

Is this an HTML to PDF API?

No. Bannx renders its own templates, not web pages, and there is no browser to run. The PDF is built on our servers from the design, with selectable text and the fonts embedded.

Can one PDF have several pages?
