How is this different from other online PDF tools?

Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.

Are my PDF files uploaded?

No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.

Can I verify that files are not uploaded?

Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.

Does this tool work offline?

Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.

What happens when I refresh the page?

Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.

Does this tool store my files?

No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.

Can this tool unlock password-protected PDFs?

No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.

What technologies does this tool use?

This tool uses client-side JavaScript and pdf-lib to read and update the document information metadata fields within the PDF structure, entirely in your browser.

Does this tool use WebAssembly?

No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.

How do I edit a PDF's metadata with this tool?

Pick a PDF with the file selector, and the title, author, subject, keywords, and creator fields are read in your browser and pre-filled. Change any of them, click Apply, and save the updated PDF back to your device. Everything happens locally in the browser, with no file leaving your machine.

Why can I see the Producer field but not change it?

Producer is shown read-only because pdf-lib stamps its own producer value into the document every time it saves, so any edit you made there would be overwritten in the output. Only the title, author, subject, keywords, and creator fields are actually editable and saved.

Why didn't clearing the author still show my name in another viewer's properties?

Many PDFs from Acrobat, Office, or InDesign also keep title and author inside a separate XMP metadata stream, not just the document info fields. When you apply changes, this tool removes that XMP stream so your edited fields are authoritative and stale values like an old author name aren't left behind.

Does the Edit PDF Metadata tool cost anything to use?

Edit PDF Metadata is completely free — no account, no sign-up, and no cap on how many PDFs you edit — and it always will be. Because the tool reads and rewrites your document's title, author, subject, and keywords fields entirely within your browser using pdf-lib, your file is never sent to a server, so there is no infrastructure cost to pass on to you.

Edit PDF Metadata Privately — Your Document Never Leaves Your Browser

Select a PDF, edit the title, author, subject, keywords, and creator fields, and download the updated file — all changes are made locally in your browser.

Quick answer

What it does: Select a PDF, edit the title, author, subject, keywords, and creator fields, and download the updated file — all changes are made locally in your browser.

How it works

Select a PDF file from your device using the file picker.
The file is read into browser memory — no data leaves your browser.
pdf-lib reads the existing document information fields (title, author, subject, keywords, creator) and displays them for editing.
Edit any of the fields and click Apply — pdf-lib writes the updated values into the PDF structure.
The updated PDF is offered as a download directly from your browser.

When to use this tool

Correcting the author name or title on a PDF before publishing it, since search engines read document metadata.
Blanking metadata fields that reveal internal details (e.g. original author, creator tool) before sending to clients.
