How read form fields works here

List all AcroForm fields with names, types, current values and locations (JSON). The whole job — parsing, processing and saving — happens in this browser tab using open-source libraries (pdf-lib / PDF.js). Close the tab and nothing remains anywhere.

People often pair this with watermark pdf and add page numbers — same deal there: free, private, no sign-up.

Parameters

This operation takes no parameters — just the file.

FAQ

Is Read form fields free?

Yes — completely free, with no watermark, no sign-up and no trial clock. On the API/MCP side every key gets 250 guaranteed operations a day plus unlimited burst operations on spare capacity. See the pricing page for the full (short) policy.

Does my file get uploaded to a server?

No. This tool runs entirely in your browser with the same libraries the pros use — your file never leaves your device, so there is nothing to store, log or leak.

Can I automate Read form fields with an AI agent or code?

Yes — the exact same operation is a tool on the pdfmcp MCP server (for Claude, Cursor, ChatGPT and other agents) and an endpoint on the REST API. One free key works for both; the guides walk you through setup in about a minute.

Are there limits?

Files up to 100 MB and 500 pages. Web tools are additionally bounded by your device's memory. The caps exist to stop abuse and keep the shared machine fair — they are not a paywall, and there is no paid tier to unlock.
