What this tool does

Delete AcroForm fields and their stored values from a PDF locally, producing a new copy without hidden interactive form data.

Practical limit: This removes standard AcroForm fields. Dynamic XFA forms and encrypted PDFs are outside this browser tool’s supported range.

Supported formats and limits

Input: standard PDF files readable by PDF.js. Output: a newly generated PDF copy. Encrypted, damaged, or XFA-heavy files may not work.

Tips for better results

  • Keep an untouched backup of the original.
  • Process large documents on a desktop browser with free memory.
  • Verify sensitive documents in a second PDF reader.

FAQ

Does remove hidden pdf form data upload my document?

No. Processing runs in your browser. The page does not send the selected PDF to a document-processing server.

Can this tool open a password-protected PDF?

No. Remove the password with the correct credentials before using this page. Encrypted files may fail during parsing.

Will the downloaded result preserve every advanced PDF feature?

Standard pages are supported, but complex XFA forms, unusual embedded objects, and vendor-specific metadata may not be preserved.

What should I do with a very large PDF?

Try a smaller file or split the document first. Browser memory limits vary by device, page count, and image resolution.

How can I verify the result?

Open the downloaded file in a separate PDF reader and inspect the relevant pages or properties before sharing it.
