Online PDF Cropper

PDF cropping is a fully web-based tool that trims the margins of every page in a PDF straight from your browser. It uses PDF-lib to modify each page's CropBox directly without re-compressing the content, so text and images keep their original quality.

Black borders around scanned pages, excessive white space you want gone before printing, or pages that need to be aligned to a uniform size — the cropper fixes all of it in seconds. Your files never leave your device, so it's the safest choice for confidential documents too.

Common Cropping Use Cases

  • Remove scanner borders — trim the extra margins a scanner adds for cleaner, tidier printouts.
  • Reduce document white space — cut blank areas to save paper and storage.
  • Align page sizes — crop pages from different sources to a consistent text block.

Why It's Better Than Desktop Software

  • Works anywhere — no installation needed; works on Windows, macOS, Linux, iOS and Android.
  • Zero privacy risk — files are processed locally and never sent over the network.
  • Lossless quality — only the visible area changes; page content is never re-compressed.

PDF Cropping FAQ

Answers to the most common questions about cropping PDF files online.

Is this online PDF cropper really free?

Yes. It's completely free — no limits, no watermark, no registration. All processing happens locally in your browser.

Will my files be uploaded to a server?

No. Your files are processed entirely on your own device and are never sent to any server, so your documents remain only on your computer.

Will cropping reduce the quality of my PDF?

No. Cropping only adjusts each page's visible area (the CropBox) without re-compressing the content, so text and images keep their original, highest quality.

Can I crop only certain pages?

The current version applies the same crop to all pages. If you need to crop just a few pages, first extract them with the "Split PDF" tool.
