PDFops is a hosted HTTP API for programmatic PDF work, built to run on edge platforms such as Vercel and Cloudflare Workers. It fills AcroForm fields — text, checkboxes, dropdowns, radio groups, and option lists — and merges multiple PDFs, returning the resulting file in the response. There is no headless browser and no per-document render step, so it can be called directly from an edge function. Output is deterministic, which suits audit-sensitive workflows like tax and insurance forms.

PDFops FAQ
What can the API do today?
Two operations: fill the form fields of an existing AcroForm PDF, and merge several PDFs into one. Both return the resulting PDF in the HTTP response.
Do I need to sign up to try it?
No. During beta the API is open with a cap of 100 requests per IP per month, so you can test fill and merge without authentication.
How is it different from browser-based PDF tools?
PDFops runs server-side on edge runtimes and operates on the raw PDF without rendering it in a headless browser, so it can be called directly from a Vercel or Cloudflare edge function.
