About the Crop PDF tool

Crop PDF trims a fixed margin off the top, bottom, left and right of every page in a PDF — useful for removing scanner borders, watermarked edges, wide margins on scanned books, or excess white space before printing.

How it works

Upload a PDF and the first page renders as a live preview. Drag the four sliders to set how much to trim from each side (as a percentage of the page), watch the dimmed preview update, then click Crop & download. The same crop is applied to every page in the document.

Assumptions and behaviour

Crop is applied as a percentage of each page's own size, so it scales correctly even if pages differ in size.
Uses the PDF's crop box, not rasterization — text stays selectable and file size barely changes.
The same margins apply to every page in the document; per-page custom cropping isn't supported.
Content outside the crop box is hidden, not deleted — most viewers respect the crop box, but the original content technically remains in the file.

Limitations

No freeform drag-to-select crop box yet — margins are set as percentages via sliders.
Rotated pages or pages with unusual crop/media boxes may not preview pixel-perfectly, though the underlying math still applies correctly per page.
Encrypted or password-protected PDFs can't be processed.

Privacy

The PDF is cropped entirely in your browser using pdf-lib. Nothing is uploaded or stored.

Frequently asked questions

Is this Crop PDF tool free?

Yes — free, no sign-up, no limits, runs in your browser.

Does cropping reduce text quality?

No. Cropping only adjusts the visible page boundary (the crop box) — text and vector content stay exactly as sharp as the original.

Can I crop each page differently?

Not currently — the same margin percentages apply to every page. This covers the common case of trimming uniform scanner borders or margins.

Will this reduce file size?

Only slightly. Cropping hides content outside the crop box but doesn't remove it from the file, so it isn't a compression tool — use Compress PDF for that.

Is my PDF uploaded anywhere?

No. Everything runs locally in your browser; nothing is sent or stored.
