Does cropping delete the content outside the crop area?

Technically, a PDF crop box only hides content — it does not permanently delete it from the file. Most viewers will show only the cropped area, but someone with the right tools can reveal the hidden content. For true removal, use the Redact PDF tool.

Can I crop different areas on different pages?

The current tool applies one crop box uniformly to all pages. Per-page cropping is planned for a future update.

How do I remove large white margins from a scanned document?

Scan documents often have wide white borders. Draw your crop rectangle tightly around the text content — excluding the white borders — and download the cropped PDF.

Will the crop be visible in all PDF viewers?

Yes — the crop box is a standard PDF property respected by Adobe Acrobat, Apple Preview, Chrome, and all major viewers. The cropped area will not be visible in normal view.

使い方

3ステップでPDFをトリミングする

1
Upload your PDF
Drag and drop your PDF onto the tool or click to browse. The file loads in your browser — never sent to any server.
2
Draw the crop rectangle
Click and drag on the first-page preview to draw your crop rectangle. The selected area will be kept — everything outside will be hidden. Drag again to redraw.
3
Download the cropped PDF
Click 'Download cropped PDF'. The crop box is applied to every page using pdf-lib and your browser downloads the result immediately.

Draw to crop — visual and intuitive

Drag directly on the page preview to define exactly what area to keep. No coordinates to type — just draw and download.

Applied to all pages at once

The same crop box is applied to every page in the document simultaneously — one draw, one download, consistent across the whole PDF.

Your file never leaves your device

Cropping uses pdf-lib entirely in your browser. Nothing is uploaded or stored.
