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.

Does cropping delete the trimmed content?

It resizes the page box so the trimmed area no longer shows. Use it to remove margins or change the page shape.

Can I crop only some pages?

Yes — apply the crop to all pages, the current page, or a custom page range. Presets like A4, Letter, Square, or auto remove-margins are one click.
