Frequently asked questions

Are my files uploaded to a server?

No. ZentaPDF processes your files inside your own browser using JavaScript. Nothing is uploaded, so nobody else can see your documents — not even us.

Is the cropped content deleted?

The PDF page size is reduced so the trimmed area is no longer shown or printed. The hidden content may still exist inside the file, so do not rely on cropping to remove sensitive information.

Are all pages cropped the same way?

Yes. The same margins are removed from every page.

Why use Crop PDF?

To remove large white margins so pages are easier to read on a phone, or to cut away scanner borders.

Is it really free? Do you add a watermark?

Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
