100% in-browser — your file never leaves your device
Search engines and document systems read PDF titles and keywords. A report titled "Q3 2026 Financial Report — Acme Ltd" is found; one titled "Microsoft Word — Document1" is invisible. Set meaningful metadata before publishing anything.
Consistent titles, authors and keywords turn a chaotic folder of "scan_0042.pdf" files into an organized, searchable archive. Batch your renaming workflow: title first, keywords second.
Author fields frequently carry your username or full name — check what's embedded before sending a file externally. For client-facing invoices, pair this with our invoice generator and set clean attribution.
Regulated industries need reliable document properties: correct titles, version info in keywords, accurate authorship. Fix them in seconds without touching the content or buying Acrobat.
Need everything gone — including data this editor can't reach? Our Remove PDF Metadata tool sanitizes the file in one click.
Run any PDF through this tool just to read it — a 10-second audit that shows exactly what you'd be handing to a client, a publisher, or a court.
This tool edits document properties only. It cannot change text, images, layout, or remove pages — use the dedicated editors for that.
The Producer field is rewritten by the PDF engine when the file is saved — that's standard behavior in every PDF tool, including Adobe's. Everything else you set stays exactly as you typed it.
Password-protected files must be unlocked first — metadata inside encrypted files can't be read without the password.
Some files carry a second, XML-based metadata packet (XMP) alongside the classic properties. This editor handles the classic fields; use Remove PDF Metadata for full sanitization including XMP.
PDF metadata is hidden information stored inside a PDF file: the document title, author, subject, keywords, the software that created it (Creator), and the software that produced the PDF (Producer), plus creation and modification dates. It is invisible on the pages but visible to search engines, file managers, document systems — and anyone you share the file with.
Common reasons: fix a meaningless title like 'Microsoft Word — Document1' before publishing, set correct author attribution on reports and invoices, add keywords so documents are findable, remove your personal name before sharing externally, and keep document libraries consistent and professional.
No. Metadata editing only changes the hidden document properties. The text, images, layout, fonts and page count of your PDF remain exactly the same — only the 'document properties' panel and what search engines see will change.
Never. All metadata reading and writing happens locally in your browser using a JavaScript PDF library. Your file stays on your device from start to finish — verify it in the Network tab if you like. That makes this the safe way to inspect metadata on confidential documents.
Yes — click 'Clear all fields' and save, and every editable field is emptied. (The Producer field is rewritten by the PDF engine on save; the tool notes this.) For one-click complete sanitization including XMP data, use our dedicated Remove PDF Metadata tool.
The Creator field records which application originally authored the document (e.g. Microsoft Word); the Producer field records which software converted it to PDF (e.g. the PDF library). Both are editable here, though Producer is re-stamped by the engine when the file is saved.
Yes on both. Metadata lives in the file header, not in the page content, so scanned PDFs edit exactly like born-digital ones. And the tool runs in any modern browser, including Safari on iPhone and Chrome on Android.
