Crop PDF
About Crop PDF
Crop PDF trims equal margins from all four sides of every page, shrinking the page box around the content. Choose a preset (small (8 mm), medium (15 mm) or large (25 mm)) or adjust the amount yourself, and a dashed frame on each page preview outlines exactly what will be kept.
The tool also reports the resulting dimensions, for example “Page size: 210 × 297 mm → 180 × 267 mm”, so you know the output format before committing. Cropping is applied uniformly, which keeps the pages consistent for e-readers and reflows.
Cropping white margins is the classic fix for PDFs read on tablets and e-ink devices, where wasted border space makes the text needlessly small, and for scans whose generous margins push the content into a corner.
How to use Crop PDF
- Drag and drop the PDF you want to crop.
- Pick a preset (small, medium or large) or fine-tune the crop amount.
- Check the dashed frame on the previews showing the kept area, and the before → after page size.
- Click “Crop PDF”: the trimmed file downloads automatically.
Frequently asked questions
Yes. Trimming PDF margins is free.
The presets trim 8 mm (small), 15 mm (medium) or 25 mm (large) from each side, and you can adjust the amount. The same margin is removed from all four sides of every page.
No: this tool applies one uniform crop to the whole document, which keeps page sizes consistent. That is usually what e-readers and printers want.
Cropping shrinks the visible page area; make sure the dashed keep-frame in the preview contains everything you need before applying. Content outside the frame will no longer be visible.
Mostly for reading comfort: trimming white margins makes the text render larger on tablets and e-readers, and cleans up scans whose borders push content off-balance.
