How browser-based processing works here
Each selected page is redrawn — as vector content, not a rasterized image — onto a new, smaller page with your chosen edges removed, directly in your browser's memory. Pages you don't select are left completely untouched. Nothing about your document is ever transmitted anywhere.
- No file upload endpoint exists on this page
- No database or server-side file storage
- Output is generated locally as a browser Blob file
Supported files: Standard, non-encrypted PDF files, including portrait, landscape, mixed page sizes, and rotated pages. Encrypted or password-protected PDFs aren't currently supported.
Honest limitations
- Interactive form fields, annotations, comments, links, and bookmarks are not preserved on a cropped page — only its visible vector content and images are redrawn onto the smaller page.
- Cropping only removes edges — it never scales or resizes content, so there's no 'fit' or 'fill' option the way there is for Resize PDF Pages.
- The same crop amounts are applied to every selected page based on each page's own visual size, so a crop valid for one page can be too large for a smaller page in the same document — that page (and the whole job) is rejected rather than silently skipped.
No artificial daily task limits. Processing capacity depends on your device, browser, file size, and page count.
Troubleshooting
The crop amount I entered isn't accepted
Crop values must be zero or a positive number for each edge — negative or non-numeric amounts aren't accepted.
The tool says my crop removes the entire page
Reduce the amount you're cropping from one or more edges — the combined top+bottom or left+right crop can't equal or exceed the page's own visual height or width.
One page in my document has an unusual crop result
Documents with mixed page sizes or rotated pages apply the same crop amounts to each page's own visual size — if a page is smaller than others, the same crop can be too large for that page and will block the whole job until you reduce it.

Frequently asked questions
Does cropping scale or resize my page content?
No. Cropping only removes the amount you specify from each edge — the remaining content keeps its original size and position, it's the page boundary itself that gets smaller.
Can I crop only some pages in my PDF?
Yes, select specific pages from the page grid — every other page is left exactly as it was.
What happens if my document has pages of different sizes?
The same crop amounts are checked against each selected page's own visual size. If the crop would remove an entire page anywhere in your selection, the whole job is stopped with a clear message listing which pages are affected, rather than producing a partially cropped file.
Will cropping affect a rotated page correctly?
Yes — crop amounts always refer to what you see as the top, right, bottom, and left of the page on screen, regardless of the page's own rotation.
