About editing PDF metadata

Every PDF carries a small set of metadata fields alongside its pages — title, author, subject and keywords — that show up in a reader's document properties panel, in search results, and in a browser tab title, even though they're invisible on the page itself. A document exported straight from a design tool often has these set to something unhelpful, like a bare filename or the software's own name.

This tool reads the current metadata with pdf-lib, lets you set new values for title, author, subject and keywords, and writes them back into the PDF's document information dictionary — entirely in your browser. It's a quick fix that also matters for accessibility: a real, descriptive title is one of the concrete things a screen reader announces (see Accessibility Checker).

Supported files

Is my file uploaded?

No. Metadata is read and written entirely in your browser with pdf-lib — nothing is uploaded.

Edit PDF Metadata — frequently asked questions

What is PDF metadata used for?+

It's the Title, Author, Subject, and Keywords stored inside the file itself — shown in a PDF viewer's document properties panel, used by search engines and file indexers, and sometimes required by submission portals (theses, compliance archives).

Will this change how the PDF looks?+

No — metadata is invisible information about the file, not part of any page's content. Nothing on the pages themselves changes.

Can I clear a field instead of just changing it?+

Yes — empty a field and save; that removes it rather than leaving the old value.

Is there a free way to change a PDF's author or title?+

Yes — edit the Title, Author, Subject and Keywords fields directly, free and entirely in your browser.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
