How to edit a PDF’s metadata
To edit a PDF’s metadata, open Edit Metadata and its title, author, subject, keywords, creator and producer are read into editable fields. Change any of them, or clear them all, and save a new copy — the pages stay untouched.
To edit a PDF’s metadata, open Edit Metadata and drop the file in. Its title, author, subject, keywords, creator and producer are read straight out of the document and shown in editable boxes. Change any of them, or clear them all, and click Save metadata to download a new copy — free, no account, and in your browser with nothing uploaded.
How to do it
Open Edit Metadata
Go to Edit Metadata. It runs on your device — no account, no install, nothing to upload.
Drop in the PDF
The tool reads the file and fills the fields with what it currently holds: Title, Author, Subject and Keywords, plus Creator and Producer — the two the software that made the file usually stamps in.
Edit or clear the fields
Type over any value, or use Clear all fields to blank every one at once. Keywords are separated with commas.
Save the new copy
Click Save metadata. The updated PDF downloads as a new file, with its modification date set to now and everything else in the document left exactly as it was.
Can PDF metadata be edited?
Yes. Every PDF carries an information block — title, author, subject, keywords, and the creator and producer program — and all of it can be rewritten or removed. Editing it changes nothing on the pages: the text, images, form fields and bookmarks are untouched, and the file barely changes size. It is a lossless edit.
What metadata does a PDF store?
A PDF holds two things you can edit here — Title, Author, Subject and Keywords, which describe the document — and two it mostly fills in itself: Creator and Producer, naming the program that made the file. It also records a creation date and a modification date. Together these are often the quiet giveaway of who made a file and with what.
How do I remove all metadata from a PDF?
Click Clear all fields, then Save metadata. Every property — title, author, subject, keywords, creator and producer — is blanked in the saved copy. It also strips the hidden XMP block, a second copy of the same information that many PDFs carry alongside the plain one, so a viewer reading that instead finds nothing left behind.
How do I edit PDF metadata in Adobe Acrobat?
In Acrobat you open File, then Properties, and edit Title, Author, Subject and Keywords under Description, with Creator and Producer shown below. That is paid desktop software. Edit Metadata gives you the same fields, free and with no install, and reads them in your browser without the file leaving your machine.
How can I edit the metadata of a PDF for free?
Open Edit Metadata, drop in the PDF, change the fields and save — no account, no watermark, no upload. Most free metadata editors open your file on their server to read and rewrite it. This one does the whole job in the browser tab, so a document whose author or title you would rather not broadcast never leaves your device.
The tool reads your metadata with one PDF engine and writes it back with another, on purpose. The writer, pdf-lib, cannot decrypt the information block on a file that carries any encryption — including the common permission-restricted kind that opens with no password — so asking it to read the title would return a blank on a file that genuinely has one, and you would clear a field you never saw. So the fields are filled by pdf.js, the same engine a real viewer uses, which shows the values as they actually are, and pdf-lib only does the writing. A password-protected PDF still has to be unlocked first; a permission-restricted one is read and saved without a prompt.
