PDF Metadata

Edit the title, author and keywords, or strip all metadata.

PDF Metadata shows the hidden information stored inside a PDF and lets you change it, or wipe it completely before sharing the file.

How to use PDF Metadata

1. Drop your PDF into the upload box, or click it to browse. The file stays on your device.
2. Edit the title, author, subject, keywords and application fields, or remove all of them.
3. Click the button and the result downloads straight from your browser.

Questions

Is PDF Metadata free?

Yes. Every tool on ZTools is free, with no limits, watermarks or sign-up.

Are my files uploaded to a server?

No. PDF Metadata runs entirely in your browser using JavaScript and WebAssembly. Your files never leave your device and nothing is stored.

Does it work on my phone?

Yes. ZTools works in any modern browser on desktop, tablet or phone. Large files take longer on low-end devices because all the work happens locally.
