Crop PDF
Two crop modes: Auto scans each page for its content bounding box and trims the surrounding white space (keeping a small safe margin); Margins crops an exact millimetre amount from each side. Cropping only adjusts the visible page area — the content itself is untouched.

How it works (3 steps)
Upload your PDF
Scans with big borders and papers/ebooks with wide margins are ideal candidates.
Choose a crop mode
Auto is the easiest; switch to Margins when you need exact control, entering millimetres per side.
Download the result
Each page is cropped to its own content box (Auto) or by the uniform margins you set.

FAQ
No. Cropping changes the page's visible area (CropBox); the underlying content stays in the file and the original size can be restored with other tools. Auto mode also keeps roughly a 2 mm safe margin around the detected content.
Try it ↑Yes — Auto mode detects the content box per page independently, so each page is trimmed to its own best fit. Nearly blank pages keep their original size and are flagged on the result card.
Try it ↑No. Detection and cropping run entirely in your browser.
Try it ↑No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.
Try it ↑Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.
