Frequently Asked Questions

How is this different from wkhtmltopdf?+
wkhtmltopdf uses an outdated WebKit engine with poor CSS3 support. HTML2DocHub uses Chromium — the same engine as Chrome — giving you pixel-perfect results with modern CSS, Flexbox, Grid, and fonts.
Can I generate PDFs from dynamic React or Vue apps?+
Yes. Pass the rendered URL and the API will fully execute JavaScript before capturing the PDF.
What are the size and page limits?+
Default max is 100 pages per job and 10MB output. Admin-configurable limits apply.
Is there a free tier?+
Every new account gets ₹10 of free wallet credit (about 100 pages) to try the API. After that it's pay-as-you-go with no monthly minimum.
Can I run batch PDF generation?+
Yes. Use async mode with a webhook URL. Submit multiple jobs concurrently and receive callbacks when each is ready.
