Edit PDF Metadata
Change the Author, Title, Subject, Keywords, Producer, or Creation Date on any PDF. Runs entirely in your browser — no upload, no signup.
Free. Unlimited files. Works offline after first load.
What you can edit
The editor exposes every field in the document's /Info dictionary as a regular form input. Type new values, click Save changes, download the modified PDF:
- Title — the human-readable document name (often shown in browser tab titles and reader window headers).
- Author — usually defaults to the OS username of whoever generated the file. Frequently embarrassing.
- Subject — a one-line description used by some catalog tools.
- Keywords — comma-separated tags. Often picks up Office template tags.
- Creator — the application that created the source (e.g. "Microsoft Word for Microsoft 365").
- Producer — the library that wrote the PDF (e.g. "Mac OS X 10.14 Quartz PDFContext"). Reveals your OS.
Blank a field to clear it entirely. The output PDF is byte-clean — old values are gone, not just hidden.
White-label any PDF
Clear the Producer and Creator fields before sending a deliverable to a client. Hide that it was generated by a free tool.
Compliance-friendly
Strip identifying author names from board materials and legal filings before circulation. Runs locally — nothing for compliance to worry about.
Files stay on your device
WebAssembly does the rewrite in your browser. Disconnect Wi-Fi after the page loads to verify.

FAQ
Will the edit show up in Acrobat's File > Properties dialog?
Yes. The fields you change here populate the same dialog Acrobat reads. They also propagate to the XMP metadata stream where applicable.
Can I edit the CreationDate?
Yes, but be aware that some PDF readers cross-check against the XMP timestamp. To keep them consistent, use Remove mode to strip XMP first, then edit dates.
Does this re-save the entire PDF?
Yes. The output is a fresh PDF written by MuPDF — old values are physically replaced, not just shadowed. We also strip incremental updates that could carry forward old metadata.
Will it work on encrypted PDFs?
Only if you have the password. Editing a password-protected PDF requires unlocking it first.
What about custom metadata fields?
The v1 editor exposes the standard /Info dictionary fields. Custom XMP properties can be removed via Remove mode; editing arbitrary custom XMP is on the roadmap.
