Frequently asked questions
Is this PDF cropper free?
Yes, it's completely free with no sign-up, no install, and no watermark. You can crop as many PDFs as you want.
Is my PDF uploaded to a server?
No. Everything happens locally in your browser, so your file never leaves your device. That makes it safe for confidential and private documents.
How does the cropping work?
You set a percentage to trim off the edges, and the tool sets a new crop box on every page using pdf-lib. The same trim is applied uniformly across all pages.
Does cropping permanently delete the content outside the crop box?
Not exactly. Setting the crop box hides the trimmed margins so they no longer display or print, but the underlying content technically remains in the file and could be recovered. Don't rely on it to strip sensitive information from the edges.
Can I crop each page differently or set exact dimensions?
No. This tool trims by a single percentage applied to every page, which keeps the document consistent. It doesn't support per-page crops or precise pixel dimensions.
Are there file size or format limits?
It works with standard PDF files and runs entirely in your browser, so very large files are limited mainly by your device's memory. Bigger documents may take a little longer to crop.
