Crop PDF: free online, fast and secure
Wide margins make PDFs hard to read on phones and waste paper when printing. Cropping trims the edges so the content fills the screen or page.
Set top, right, bottom and left margins as a percentage and watch the highlighted area on the preview. Apply the crop to all pages or only the first page.
How to use Crop PDF
- Choose a PDF. Upload the file; page 1 appears as a preview.
- Set the margins. Move the four sliders until the box covers the part you want to keep.
- Crop. Press “Crop PDF” and download.

Good to know
There are two kinds of PDFs: digital PDFs created from Word, Excel or a website, which contain selectable text, and scanned PDFs, which are just photos of paper pages. Tools that edit pages, like Crop PDF, work with both. Tools that read text work only with digital PDFs. If you can select a word in your PDF viewer, your file has a text layer.

How Crop PDF keeps your PDF documents private
When you add a file to Crop PDF, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential PDF documents like ID proofs, bank documents, contracts and family photos.
