Frequently asked questions

Is my PDF uploaded to edit its metadata?

No. The metadata is read and rewritten entirely in your browser, so your file never leaves your device.

Which document properties can I change?

You can edit the title, author, subject, keywords, and creator fields stored in the PDF's metadata.

Does it work offline?

Yes — once the page has loaded, you can edit metadata with your internet disconnected.

Is there a file-size limit?

Free use is capped at 25 MB per file. Pro ($5/mo) removes the cap and adds batch processing across many files.
