What Does "Crop PDF" Do?
Cropping a PDF trims away unwanted space from the edges of every page — wide margins, scanner white space, or a border you don't need — without touching the actual content. Our tool lets you set exactly how much to trim from the top, bottom, left, and right of each page as a percentage, applied consistently across the whole document in one pass.
How to Crop a PDF Online — Step by Step
- Upload your PDF. Drag and drop the PDF you want to crop into the box above.
- Set your margins. Enter how much to trim from the top, bottom, left, and right, as a percentage of the page.
- Crop and download. Click "Crop PDF" and download the file with the new, trimmed page area.
Why Use Our PDF Cropper?
- Independent control over all four margins — top, bottom, left, right.
- Applied to every page at once, consistently.
- Non-destructive to content — cropping adjusts the visible page area, not the underlying text or images.
- Private — your file is automatically deleted within 2 hours.
Frequently Asked Questions
Does cropping delete content permanently?▾
Cropping changes each page's visible area (its CropBox); content outside that area is hidden by PDF viewers and printers, which is the standard, safe way most PDF tools crop.
Can I crop different amounts on different pages?▾
This tool applies the same margins to every page — for varying margins per page, you would need to crop the PDF in sections using Split PDF first.
How do I know how much to crop?▾
Start with a small percentage (5-10%) and preview the result — you can always re-upload the original and try a different value.
Will cropping reduce the file size?▾
Usually only slightly — cropping changes the visible area, not the embedded content, so file size stays roughly the same.
