Phone scans include the table, a thumb, and a black scanner border. Printers and visa portals still store those pixels. Cropping keeps the page and throws away the noise.

Steps

  1. If the page is sideways, Rotate PDF first. Cropping a sideways scan keeps the sideways page, only smaller.
  2. Open Crop PDF and drop the file.
  3. Use an even margin when every page has the same black edge. Draw a box when only one page has a thumb in the corner.
  4. Download and zoom to 150%. If a stamp or a page number was clipped, undo with a looser box.
  5. Then Compress PDF. You just deleted the pixels the encoder was spending bytes on.

One page, not the whole file

Crop is a page box. If page 4 of 12 is the only bad scan, Split PDF page 4, crop that file, then Merge PDF it back into place. Do not crop a tight box onto the other eleven pages.

The new PDF is written in this tab. The original file on your phone is unchanged until you delete it yourself.
