Edit PDF Metadata

Every PDF carries hidden details: a title, an author, keywords, the app that made it and when. They decide what appears in a reader’s title bar, how the file shows up in search engines and document libraries, and sometimes they give away more than you meant — an old client’s name in the title, your full name as author, or the draft date of a “final” report.

This tool shows all of it and lets you change it. Edit the eight standard fields and the language, tick the box to show the title instead of the file name, and save. PDFs keep their details twice — in the Info dictionary and in an XML copy called XMP — and many apps read the XMP first, so we rewrite both to match. Alongside, you get the facts a file doesn’t advertise: PDF version, page sizes, fonts, form fields, attachments, and a clear warning if it contains JavaScript.

Got a stack of files? Drop them all in, set the author once and copy it to the rest. Or choose “Remove all metadata” to strip every detail before publishing. It all happens in your browser, so the files never leave your device.

1. Tap “Choose PDFs” or drop one or more files onto the box. Each file gets its own tab.
2. Change any field. Clear a field to remove that detail. Type keywords and press Enter after each.
3. With several files, press “Use for all files” beside a field to copy its value to every other file.
4. Or switch to “Remove all metadata” to strip the details from every file instead.
5. Press “Save PDF” (or “Save 3 PDFs”), then “Download”. Several files come as one ZIP.

• Edit title, author, subject, keywords, creator, producer, created date, modified date and document language.
• Keywords as chips: press Enter or a comma, paste a whole list, Backspace to remove the last.
• The XMP copy is rewritten to match your edits, keeping any PDF/A or PDF/UA conformance note.
• Batch mode for up to 30 PDFs, with a one-click “Use for all files” on every field.
• Remove all metadata: Info dictionary, document XMP, and XMP attached to pages and pictures.
• Read-only facts: PDF version, page count and named sizes, fonts and whether they’re embedded, form fields, attachments, tagging and protection.
• Warns when a PDF contains JavaScript, and says where it was found.
• Shows the raw XMP so you can see exactly what other apps will read.
• Each saved file is read back to confirm the new details stuck.

• If a reader still shows an old title, it is probably reading a cached copy. Close and reopen the file.
• Tick “Show the title in the reader’s window bar” for reports and e-books, so readers see “Annual Report 2026” rather than final_v3.pdf.
• The language field matters for accessibility: screen readers use it to pick a voice. Use a code like en-GB, fr-FR or hi-IN.
• Saving re-writes the file, so a digital signature inside it will show as changed. Edit details before signing, not after.
• Password-protected PDFs can’t be read here. Remove the password with Unlock PDF, edit, then protect it again if needed.
