Edit PDF Metadata

1. Choose your PDF, or drop it onto the box. It opens in your browser, so the file never leaves your device.
2. Change the boxes you want. The tool fills them with what the PDF holds now. Type over a value to change it, or empty a box to remove that detail from the file.
3. Click Save and download. You get a copy named yourfile-edited.pdf; the original is untouched. The boxes then show what the new copy contains, so you can check it.

Metadata is the information about a PDF, the details you see under File → Properties in a PDF reader. Changing it does not touch the text, pictures or layout on the pages, and the file stays the same quality.

Password-protected PDFs need to be unlocked first, because a locked PDF can be read but not changed.

A PDF often stores these details twice: once in the classic document information list and once in a block of XMP metadata. Readers may show either one, which is why a title changed in one place can still show the old value elsewhere. This tool writes your changes to both, so every reader agrees.

When a PDF has a Title, most web browsers show it in the tab instead of the file name. Renaming the file doesn’t change it, because the title is stored inside the PDF. That is how a file called invoice-2041.pdf can open as Microsoft Word - Template1.

• To show a proper title, type it in the Title box and save.
• To show the file name instead, empty the Title box and save. With no title, readers fall back to the file name.
• For Adobe Acrobat and other desktop readers, tick Ask PDF readers to show this title instead of the file name. Many desktop readers show the file name unless the PDF asks for the title.

If the old title still appears, check that you opened the downloaded copy, not the original.

Click Remove all metadata to download a copy with every detail removed: all the fields above, custom properties, the XMP block (including the copies some PDFs keep for each page and picture), and private editing data that design programs leave behind. Older copies of the details left in the file by earlier edits are removed too, so they can’t be dug back out.

To clear only some details, empty those boxes and use Save and download instead.

Before you share the file, keep in mind what metadata doesn’t cover:

• Names on the pages stay. A name in a header, footer or signature line is page content, not metadata.
• Comments keep their author. Sticky notes and highlights usually record who made them. Remove them with Remove PDF annotations.
• Signed PDFs lose their signature. Any change to a signed PDF breaks the signature, so edit the details before signing. The tool warns you when it spots one.
• Archive PDFs (PDF/A) need their metadata. Removing all of it means the file no longer counts as PDF/A. Editing the fields is fine: both copies are updated together, as PDF/A requires.
