Remove white borders, cut away unwanted margins and resize PDF pages to exactly what you need. See the crop area live before you apply it. Files never leave your device.
Choose a file or drag it onto the drop zone. It stays on your device — nothing is uploaded.

No. Cropping only changes the visible page area (the CropBox) — it does not recompress images or text, so the content keeps its original quality. The hidden content outside the crop area is still in the file but not displayed.
Yes. Choose All pages to crop every page, or enter a page range such as 1-3, 5, 7-9 to crop only those pages. Unselected pages keep their original size.
Points (pt) are absolute units — 1 inch = 72 points — so a 36 pt margin is always half an inch regardless of page size. Percent margins are relative to each page's width and height, so 10% trims the same proportion on every page even if pages differ in size.
No. TheEditPDF processes files 100% in your browser using pdf-lib and pdf.js. Your PDF never leaves your device, which is why the tool works offline once loaded and needs no account.
Yes — that is the most common use. Set equal margins on all four sides (for example 10% or 36 pt) and use the live preview to check the result before applying. For uneven borders, adjust each side separately.
