What is PDFops?

Editorial review
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.
