What does cropping a PDF do?

Cropping sets a visible area on each page and hides everything outside it — useful for trimming wide margins, removing headers or footers, or zooming in on the content that matters. The page content is preserved; only the displayed and printed area changes.

How it works here

The first page is rendered as a preview; you drag a box to choose the crop area, and that same area is applied to every page using its crop box. Everything runs in your browser with pdf-lib — your file is never uploaded.

When to crop a PDF

Remove large white margins to fit more on screen, trim a scanned page down to the document, focus a handout on one figure, or standardise pages before merging or printing. It is a quick way to tidy up a PDF without an editor.

Cropping vs deleting content

Cropping changes the visible crop box but does not delete the underlying content — a viewer that ignores the crop box could still reveal trimmed areas. For removing sensitive content permanently, redact or rebuild the page rather than crop. Works best on unrotated pages.

FAQ

Is my PDF uploaded?+

No. The crop is applied in your browser with pdf-lib, so your file never leaves your device.

Does the crop apply to all pages?+

Yes. The area you select on the preview is applied to every page using its crop box.

Does cropping delete the trimmed content?+

No. Cropping hides content outside the crop box but does not remove it. To remove sensitive content permanently, redact or rebuild the page instead.

Why does my cropped page look off?+

Cropping works best on unrotated pages. If a page has a rotation set, the crop area may not line up as expected.

Is it free?+

Yes, completely free — no sign-up and no watermark.

Is my data private?+

Yes — this tool runs entirely in your browser. Your files and text are never uploaded.
