Drag the corners to set the crop area
Crop PDF lets you trim the margins or zoom in on part of every page. Upload a PDF, drag the corners of the selection box over the page-1 preview to choose the area you want to keep, then apply it. The same crop is applied to all pages using pdf-lib, entirely in your browser, so your document is never uploaded and its content stays untouched, only the visible page area changes.
Cropping a PDF is the quickest way to clean up documents that carry more page than you need — wide scanner margins, a slide exported with borders, or a spreadsheet printed with acres of white space. Drag the corners of the selection box over the first-page preview to mark the area you want to keep, and the same crop is applied proportionally to every page, so a whole document is trimmed to a tidy, consistent size in one step.
The crop works by setting a new visible page area rather than rewriting the file, so it is fast and completely lossless — your text and images stay at full quality and the trimmed parts simply no longer show or print. Everything happens in your browser with the open-source pdf-lib library, so your document is never uploaded and nothing is stored on a server. It works on Windows, macOS, Linux, Android and iOS in any modern browser, so you can crop a PDF on your laptop or your phone without installing an app.
