How to reach us.
Email-first. We run a small team — messages come straight to an engineer, so please include request IDs, error codes, and reproduction steps where possible.
/ Support
Integration help
Stuck on a curl, a PDFOption, or a job stuck in queued state? We prefer email — it keeps a paper trail we can both reference.
Email support → support@21pdf.com/ Account
Billing & plans
For quota changes, invoice copies, or card updates — log in and use the dashboard first. Razorpay hosts the billing portal.
Email billing → billing@21pdf.com/ Security
Disclosures & questions
Responsible disclosure, DPA requests, or questions about our SSRF handling. Please encrypt if you can; GPG key on request.
Email security → security@21pdf.com/ Sales
Higher-volume needs
If Business (50k/mo) isn’t enough, tell us your volume, region, and the kind of document you render — we’ll come back with a real answer, not a demo script.
