Reclaiming the white space
Two things produce badly proportioned PDFs: scanners, which surround an A5 page
with A4 of white, and phone cameras, which catch a stretch of desk around the
document. Both waste space on screen and paper, and both look careless when the
file is going to somebody else. Cropping trims the edges so the page is the
content.
A live preview, because guessing at millimetres does not work
Drag the Top, Bottom, Left and Right sliders and watch the page update. You are
adjusting until it looks right, not entering measurements and hoping — which
matters because scanner margins are rarely even, and the amount of white on the
left is usually not the amount on the right.
The trim is applied uniformly to every page, so the document stays
consistent. This is the right behaviour for a scan where every sheet has the
same border, and the wrong one if page 3 is a landscape insert. Crop pages of
one shape together.
Nothing is deleted
Cropping changes the page box — the rectangle a viewer is told to display — and
leaves the underlying content in place. Text remains text and remains
selectable, images keep their resolution, and quality is identical, because
nothing is re-rendered.
The honest consequence of that: content outside the crop is hidden, not
destroyed, and another tool can reveal it. If your aim is to make information
*go away* rather than to improve the proportions, cropping is not enough —
Redact PDF removes text from the file itself. File size stays
roughly the same for the same reason.

Frequently asked questions
How do I crop a PDF?
Upload your PDF and drag the Top/Bottom/Left/Right sliders to trim each edge. A live preview shows what stays and what is removed, then download.
Does cropping apply to every page?
Yes, the margin trim is applied uniformly to all pages so the document stays consistent.
Is any content deleted?
Cropping only hides the trimmed margin area by changing the page box — it does not delete underlying content, and quality is unchanged.
