Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

Which fields can I edit?

Title, author, subject, keywords, creator, and producer. Existing values are loaded so you can adjust them.

How do I enter multiple keywords?

Separate them with commas — they are stored as the PDF's keyword list.

Edit Metadata

View and edit your PDF's document properties.
