How it works
Every PDF carries a document information dictionary — the title, author, subject, keywords, the app that created it, the library that wrote it and the creation and modification timestamps. Drop a PDF here and those eight properties are read straight out of the file and shown as editable fields. Change what you like, blank out anything you want gone, then download a fresh copy of the PDF with the new metadata written in. Pages, text, images, fonts, links and form fields are copied through untouched — only the properties change.
Everything runs in your browser: the file is read with the File API, rewritten in memory by the pdf-lib library and saved back to your device, so nothing is ever uploaded, stored or logged. Dates are handled in UTC so the same file always shows the same timestamps wherever you open it. Leaving a field empty removes that entry from the PDF entirely, which makes this a quick way to strip identifying metadata before sharing a document. Password-protected PDFs have to be unlocked first — an encrypted file cannot be rewritten.
Frequently asked questions
How do I change the title and author of a PDF?
Drop the PDF on this page and its document properties appear as editable fields: title, author, subject, keywords, creator, producer and the creation and modification dates. Type the new values — the summary line updates as you type — then press Download edited PDF. You get a fresh copy of the file with the new properties written in, while every page, image, font, link and form field is copied through untouched. There is no page limit, no sign-up and no watermark.
Does this PDF metadata editor upload my file?
No. The PDF is read straight from your disk with the browser's File API, rewritten in memory by the pdf-lib library running inside this page, and saved back to your device. Nothing is ever sent to a server, stored or logged, which makes it safe for contracts, invoices, CVs and unreleased client work — and it keeps working after you go offline.
Can I remove all metadata from a PDF before sharing it?
Yes. Press Clear all fields (or empty individual boxes) and download: any property left blank is deleted from the PDF's document information dictionary rather than replaced with an empty string, so the author name, authoring app and timestamps are genuinely gone. Note that this edits the standard document properties — it does not touch embedded XMP packets, digital signatures or metadata stored inside embedded images. Password-protected PDFs must be unlocked first, because an encrypted file cannot be rewritten.
