FAQ
Is cropping lossless?
Yes. The tool sets the PDF CropBox without re-encoding page content, so text and images keep their exact quality — the same technique professional PDF software uses.
How does auto trim work?
Each page is rendered to a small image in your browser, scanned line by line to find the non-white content boundary, and everything outside it is trimmed. Every page is computed independently, so mixed margins still yield tight results.
Can I crop only some pages?
Yes. Enter page numbers in "Apply to" (e.g. 1-3,5); pages not listed stay untouched. Leave it empty to apply to every page.
Is my PDF uploaded to a server?
No. Rendering and cropping run entirely in your browser. The file never leaves your device and memory is cleared on download or refresh. Limits: 50 MB and 200 pages.
