# Generate images and PDFs from templates with one API call.

Design a template once. Send it data, get back a hosted image, PDF or video. No browser to run, no layout code to keep.

[Start free](https://bannx.com/signup)[Read the API docs](https://bannx.com/docs/rendering)

25 free renders every month · No overage bills

*Nine ads from three campaigns in English, French and Spanish: rendered from one API request per ad, then re-sized into a landscape ad, a story and a banner, then downloaded together as one ZIP.*

## How it works

1. ### Design the template
   Lay it out in the browser editor, or start from the gallery. Mark the parts that change as variables.
2. ### Call the render endpoint
   Send the variables with an API key. Pick PNG, WebP, SVG, PDF, MP4, WebM, GIF or an HTML5 ad ZIP.
3. ### Use the file
   You get a hosted URL back. Or sign links once and drop them into emails and meta tags: each renders on first open.
