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.

What metadata gets removed?

Document info like title, author, subject, keywords, creator, producer, and creation/modification dates are cleared.

Does this change the visible content?

No — only the hidden document information is stripped. The pages themselves are untouched.
