Wide margins and stray edges waste space and can throw off printing. Cropping trims the page down to the part that matters, which is handy for scans, slides exported to PDF, and documents with too much white space. This guide shows how to crop a PDF with a live preview and no upload.
TL;DR Open the free crop PDF tool, pull in the edges you want to trim, and download. It runs in your browser, so nothing is uploaded.
Trim with a preview
The first page renders as a guide. Four sliders trim the top, bottom, left and right edges, and a dashed box shows exactly what each page will keep. The dimmed area around the box is what gets cut, so you can judge the result before saving.
Step by step: crop a PDF
- Open the crop PDF tool.
- Add your PDF. The first page appears as a preview.
- Pull in the edges until the dashed box frames the part you want.
- Download the cropped file.
The same crop is applied to every page, so a document with even margins comes out clean and consistent.
What cropping does to the content
Cropping sets a new visible window on each page, so the trimmed margins stop showing and printing. Your original file is never changed, because the tool builds a new PDF. If pages have very different layouts, crop them in separate sections so each gets the right window.
Everything runs on your device, with no upload, no sign-up and no watermark.
Where to go next
- Rotate a PDF to fix orientation before cropping.
- Convert a PDF to images once the pages are trimmed.
- Compress a PDF to shrink the cropped result.
