Image API · Certificate API for EdTech

Issue a certificate the moment a learner completes a course.

When your platform marks a course complete, send the learner’s name, course and date. PixlDocs returns the finished certificate as a PDF to download or a PNG to share — with a QR code pointing to your verification page if you want one.

Questions

Does PixlDocs host verification pages?

No. You encode your own verification URL in the QR code; the page lives on your platform.

Can it connect to our LMS?

Any LMS that can make an HTTPS call can use the API. A public n8n node is also available; the Zapier and Make apps are private.

Can we use our existing certificate design?

Yes. Send us your current certificate and we will show how it becomes a template.

Is it free?

Yes. PixlDocs is free for 1 year from 3 October 2026 while we work with early users. You can try a real example with no account; a free account starts with 100 credits, and you can ask us for more free credits when you run out.

Try it on sample data, then bring your own document.

Start with the free example. If your document or data source is different, send us one sample and tell us where the data lives — we set up the first template with you, free. Business and enterprise teams can contact us separately.
