How to Use Crop PDF
Crop PDF is built for people who need to trim margins or unwanted edges from PDF pages without installing desktop software. It works in the browser and keeps the workflow focused: upload the right file, choose the available options, process the document, and download the result.
This guide walks through the practical steps, explains what files to prepare, and lists the small checks that help you avoid failed uploads or confusing output.
When to use Crop PDF
Use Crop PDF when you have one PDF file and need a cropped PDF. It is especially helpful for removing scan borders, focusing on content, cleaning printable pages.
For the best experience, start with the clearest source file you have. If a document is password protected, damaged, scanned at low quality, or very large, fix that issue before processing whenever possible.
