Every PDF carries a small set of document properties — a title, an author, the app that created it, when it was made and last changed. They appear in a PDF reader's “Document properties” window, as the tab title in a browser, and in search results when a PDF is published online. Often they're wrong or revealing: a template's old title, a former colleague's name, the path of the Word file it came from. This tool shows every field and lets you change or remove them, right in your browser.
What's stored in a PDF's metadata
The standard fields live in the PDF's document information dictionary: Title, Author, Subject and Keywords; Creator (the app the document was written in, like Word or InDesign); Producer (the software that generated the PDF); and the creation and modification dates. Many PDFs also carry a second copy of the same information as an XMP metadata stream, and some apps add custom entries — company names, source file paths, document IDs — which this tool lists separately so you can see and remove them.
When to change or remove it
- Sending a document outside your organization. The Author field often holds the name of whoever created the original template — sometimes someone who left years ago — and custom fields can leak internal folder paths.
- Reusing a template. A contract or invoice built from last year's file still carries last year's title and subject until you change them.
- Publishing PDFs online. Give each document a proper title, author and keywords so search engines and document libraries describe it correctly.
- Anonymous submissions. For blind peer review, anonymized job applications or confidential reports, remove every identifying field before you send the file.
- Tidying up scans. Scanned PDFs often have no title at all, or a generic one like “Scan0042” — give them a readable one.
How it works
The PDF is opened in your browser with the open-source pdf-lib library. Only the fields you actually change are rewritten; everything else — pages, text, fonts, images, links, form fields — is copied into the new file untouched. Because the file is saved fresh rather than appended to, older revisions of the metadata that some editors leave hidden at the end of a PDF are dropped too. Nothing is uploaded: the file never leaves your device.
Frequently asked questions
Will editing the metadata change my PDF's content?
No. Pages, text, images, links and form fields are copied unchanged. The file size can shift slightly because the PDF is re-saved in a clean, compact structure.
Is my PDF uploaded to a server?
No. The file is read, edited and saved entirely in your browser. Nothing is sent over the network — you can even disconnect from the internet once the page has loaded.
Why does Adobe Acrobat still show the old title?
Acrobat prefers the XMP copy of the metadata when a PDF has one. Keep the “Remove the XMP metadata copy” option ticked when you save, and Acrobat will show your new values.
What's the difference between Creator and Producer?
Creator is the application the document was originally written in, such as Microsoft Word or Google Docs. Producer is the software that turned it into a PDF, such as a PDF printer driver or a PDF library. Both are free text, and you can change or clear either.
Does “Remove all metadata” make a PDF completely anonymous?
It removes every document-level property and the XMP stream, which is where almost all identifying metadata lives. It can't remove names written in the page content itself, author names on comments and annotations, or metadata inside images placed in the PDF — check those separately if anonymity really matters.
Can I edit the metadata of a password-protected PDF?
Not here. Encrypted PDFs have to be decrypted first, which requires the password and usually the app that set it. Once the file is saved without a password, it can be edited normally.
