How it works
  1. 01Open a PDF — page 1 renders locally as your cropping canvas.
  2. 02Drag a rectangle over the area to keep; the excluded area dims.
  3. 03Click Crop. The box is applied proportionally to all pages and the file downloads.

Bad margins are the tax every scanner and export dialog charges: a third of the page is empty border, the text is small on a tablet, and printing wastes paper reproducing nothing. Cropping fixes it once for the whole document.

Doing it visually matters — margins are something you see, not something you measure in millimeters. Draw the box, check the dimmed preview, apply. And one honest caveat other tools bury: cropping hides, it doesn't erase. For content that must genuinely disappear, whiteout in the Edit tool is the right instrument.

FAQ
How does the crop box work?+

Drag a rectangle over the area you want to keep — everything outside it is dimmed so you see exactly what survives. The same box, proportionally, is applied to every page of the document.

Is cropping destructive?+

The crop sets the page boundaries to your box, so viewers and printers show only the kept area. Your original file stays untouched on disk. Note that cropped-away content is outside the visible page but technically still in the file — for true redaction of sensitive content, use whiteout in the Edit PDF tool instead.

What is cropping useful for?+

Cutting oversized scanner margins, trimming a PDF to its content for e-readers, removing letterhead bands before reuse, or tightening slides that were exported with heavy padding.

Is the document uploaded?+

No. The preview render, the crop box and the rebuilt file all happen in your browser.
