Does cropping a PDF permanently delete the content in the cropped area?

Cropping changes the visible page boundary but does not permanently erase underlying content in most PDF viewers. If you need to truly remove sensitive content from a region, use a redaction tool instead of cropping.

Can I set a different crop value for each page?

Yes. Advanced mode lets you assign individual crop settings to each page or page range — useful for scanned documents where page alignment varies.

Will cropping reduce the file size of my PDF?

Only marginally, since cropping does not delete the underlying content layers. To significantly reduce file size, use a PDF compressor after cropping.

Does the auto-detect feature work well for scanned documents?

It works well for clean scans with clear white margins. For very light or uneven backgrounds, using the manual crop editor gives you more reliable results.

Can I crop a password-protected PDF?

Yes, as long as the password allows editing or form modifications. Enter the password when prompted and the crop will proceed normally. Fully restricted PDFs cannot be cropped without the owner password.

Is the crop tool usable on a phone or tablet?

Yes. The editor is touch-optimized — drag the crop handles with your finger to set the region. The full feature set is available on mobile browsers without any app download.
