How it works

Drop a PDF, page 1 renders as a live preview.
Drag and resize the crop box directly on the page, or click auto-trim to snap it around the detected content, cutting the white margins.
Browse pages to check the box fits, then apply it to all pages, the current page, or a range.
Download the cropped PDF.

What people use it for

Trimming scanner margins so a document fills an e-reader or tablet screen.
Cutting one column or figure region out of an oversized page layout.
Normalizing mixed-size pages to a consistent visible area.

Good to know

Cropping sets each page's crop box (the standard PDF mechanism every viewer respects) but the content outside it is hidden, not deleted: text beyond the crop is still inside the file. To permanently remove sensitive content use Redact PDF instead.
One crop box is applied per run; pages with very different sizes are cropped proportionally to the same relative region.

Frequently asked questions

What does auto-trim do?

It scans the rendered page for the boundary between content and white margin and snaps the crop box to that content area with a small padding, one click instead of pixel-nudging.

Is cropping reversible?

Technically yes, because the crop box hides rather than deletes, a PDF editor could restore the full page. That is exactly why sensitive information should be redacted, not cropped.

Is my PDF processed on a server?

No. The preview uses pdf.js and the crop is applied with pdf-lib, both running in your browser.
