Crop PDF trims those margins so the page shows only what you want printed or displayed. You set how many points to cut from the top, bottom, left, and right of each page, and the tool applies that trim across the document. All four values start at zero, so nothing is removed until you choose a number, giving you control over how tight the crop is rather than guessing. A page of typed notes might need only a few points shaved off each side, while a scan with a heavy border could need a much larger cut. ### Where the file is processed Smaller, straightforward PDFs are cropped right in your browser. Larger or more complex files go over a secure connection to the servers instead and are deleted within the hour, so you never have to wonder where the file went. - Measure your margin in points before typing a number, since guessing too high can cut into real content. - Preview the result and adjust one side at a time if text or images end up clipped. - Use Organize PDF first if you also need to rearrange pages, since cropping only changes margins. ## How to use the Crop PDF tool 1. Add your PDF file: drag & drop or click to browse. 2. Set your options: Top margin (pt), Bottom margin (pt), Left margin (pt), Right margin (pt). 3. Click “Process Crop PDF” and download your result. ## Common questions ### Is Crop PDF free? Yes. Crop PDF is free for light use with no signup needed.
