PDF Metadata Editor — Edit Title, Author, Keywords

Edit PDF metadata right in your browser — nothing is uploaded. The title shown in browser tabs and search results, and the author and keywords that document systems index, come from the PDF’s properties — often left as “Untitled” or a scanner’s name.

The boxes fill in from the PDF you open. An empty box removes that property.

Stored exactly as typed, for example: tax, 2026, invoice.

The program that wrote the PDF.

Nothing is uploaded. This tool runs entirely in your browser, so the file never leaves your device. There is no server to send it to, no copy kept anywhere, and it keeps working if you lose your connection after the page has loaded.

  2. Check the settings The defaults suit most files.
  3. Download Save one file, or all of them as a ZIP.

How to edit PDF metadata

  1. Drop your PDF file on the box above, or click it to choose the file — or press Load a sample to try it first.
  2. Check the settings below the box; the defaults suit most files.
  3. Press Convert. Long jobs show a progress bar and can be cancelled; you then see what was made and its real size.
  4. Download the .pdf file.

What is kept when you edit PDF metadata

  • Title, author, subject, keywords, creator and producer are read from the file and shown in the boxes; change any of them, or empty a box to remove that property. Any language and script can be used.
  • A PDF can store its properties twice: in the classic document-information dictionary and in an XMP metadata packet. Both are updated together and read back from the saved file, so readers that prefer XMP show the same values. Other XMP data — copyright, PDF/A identification, titles in other languages — is kept.
  • Pages, bookmarks, links and form fields are not touched. If the XMP packet is damaged or stored in a way this tool cannot decode, nothing is changed and the tool says why, rather than updating only one copy.

About PDF files

A PDF holds pages that look the same on every device: text with its fonts, vector drawings and images at fixed positions. Pages can be rotated, reordered or copied between files without redrawing them. It opens in any browser, Acrobat Reader, phone and tablet viewers.

Good to know

  • A PDF that asks for a password when you open it cannot be processed here; protection is never removed.

Privacy and limits

The file is read and converted by this page in your browser; there is no upload and no account. Nothing inside a PDF is run: there is no PDF JavaScript engine on this page, and links and forms are copied, not followed. Encrypted PDFs are refused rather than unlocked. PDFs may have up to 2,000 pages. Files up to 150 MB are accepted; a file of the wrong type or a damaged file is rejected with the reason.

Frequently asked questions

Why does my PDF reader still show the old title?

Some readers show the file name instead of the title. In Acrobat Reader, choose File › Properties › Initial View › Show: Document Title. Browsers show the title in the tab when the PDF has one.

Does editing metadata remove hidden information?

It changes the six properties shown here and, if you choose, the modification date. It is not a full sanitiser: comments, attachments, earlier revisions inside the file and other XMP fields are not removed.

Is my file uploaded to a server?

No. The conversion runs in your browser on your own device, and this page has no upload endpoint. The PDF libraries (about 2 MB) are downloaded from this site the first time you open a PDF, then cached.

Is there a size limit?

One file of up to 150 MB at a time. PDFs may have up to 2,000 pages. Larger files can exhaust a browser tab’s memory, so the tool refuses them with a message instead of failing halfway.
