List every AcroForm field in a PDF in your browser: name, type, value, read-only and required flags — exportable as CSV. Read-only.
RO — read-only fields, set by the author. Req — required fields, which every conforming reader must enforce before submit.
Values are exactly what the file stores — odd encodings and stale appearances included. Nothing is decoded or beautified.
Flatten the form with the PDF Flatten tool once you have the inventory.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
Before you flatten, fill or screen a form, you want the actual list: names exactly as the file stores them, types, current values and the read-only/required bits that decide behavior in every reader. That list is what this tool gives you — nothing more, and nothing hidden.
Field names are the keys integrations use: export the CSV into a mapping document and you have machine-processable form structure without opening the file.
Values are what the file contains, including odd encodings, empty strings and stale appearances. Decoding them into something prettier would hide real data in a compliance context, where “what the file says” is the only defensible answer.
No. PDF Form Field Inspector runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
Yes, PDF Form Field Inspector is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
PDF Form Field Inspector supports .pdf files up to 100MB directly in your browser.
Every AcroForm field: text fields, checkboxes, radio groups, dropdowns, list boxes, buttons and signature fields — with current values, read-only and required flags.
No. XFA (the dynamic XML form format used by some older Adobe workflows) is outside what pdf-lib reads; the tool reports the document as having no AcroForm rather than guessing.
No — inspection only. To flatten the fields into static content, use the PDF Flatten tool; to fill them, use whatever your PDF reader offers.
No. The form is parsed in this tab; nothing leaves your device.
