About the PDF Metadata Editor

Reads a PDF's title, author, subject and keywords into editable fields, then saves your changes into a new downloadable file.

Authors and publishers use it to set the correct title and author metadata before distributing a PDF, while businesses use it to add subject and keyword metadata so internal documents are easier to find later. It's one of many free PDF tools on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

FAQ

Frequently asked questions

Quick answers to common questions about the PDF Metadata Editor.

What does PDF Metadata Editor do?

It reads a PDF's title, author, subject and keywords into editable fields, then saves any changes into a new downloadable file.

Is PDF Metadata Editor free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many files you edit.

Is my file safe when I use this tool?

Yes. Your PDF is read and edited entirely in your browser using a small PDF library loaded from this site — it's never uploaded to a server.

Does editing metadata change the visible content of the PDF?

No. Only the invisible metadata fields — title, author, subject, keywords — are changed; the pages themselves are untouched.

Why are the fields disabled right after I choose a file?

They stay disabled until the file finishes loading and its existing metadata is read in, so you can't accidentally type into fields before there's anything loaded to save changes onto.

Can I clear a metadata field completely?

Yes. Empty a field before saving, and that value is cleared in the downloaded PDF.

Can I use PDF Metadata Editor on my phone?

Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.

Does PDF Metadata Editor have any limitations?

It edits title, author, subject and keywords only — for other details like page count or PDF version, use the PDF Info Viewer, which reads (but doesn't edit) that information.
