Crop PDF — Trim Margins & Resize Pages Visually

Most PDFs come with more whitespace than they need — wide print margins, scan borders, watermarks at the edges, or simply a page size that doesn't fit your screen. Cropping a PDF lets you tighten that visible area down to exactly what matters, making documents easier to read on phones, cleaner to print, and far better-looking when embedded in slides or web pages. Our Crop PDF tool gives you a visual, slider-driven way to do it without installing anything.

Drop your PDF and the first page renders as a live preview. Use the top, right, bottom, and left margin sliders to dim out the parts you want to cut away — the bright rectangle in the middle is exactly what your output will contain. Choose whether to apply the same crop to every page or just the first page, then hit Crop & Download to get a fresh PDF with the new dimensions.

Under the hood, the tool rewrites each page's crop box rather than rasterizing your content, which means text stays selectable, images stay sharp, fonts stay intact, and file size stays small. This is true vector cropping — exactly what professional PDF editors do — so the output is indistinguishable in quality from the original.

This is the ideal tool for trimming margins on scanned books, removing browser chrome from saved web pages, focusing slide decks on the content area, prepping documents for kindle and e-readers, and cleaning up any PDF that wastes space at the edges.
