Crop PDF
Trim an even margin off every page of a PDF right in your browser — remove whitespace or scan borders, no upload.
Short answer
To crop a PDF, choose your file, set how much to trim off each side, and download the cropped PDF. It removes the same margin from all four edges of every page — handy for cutting whitespace or scanner borders. It runs in your browser, so nothing is uploaded.

What cropping a PDF does
| PDF feature | After this tool runs | Why |
|---|---|---|
| Visible page area | Trimmed by your margin | The page's /CropBox is narrowed |
| Content outside the crop | Hidden, not deleted | It remains in the file beyond the crop box |
| Text & images inside | Untouched and selectable | Nothing is re-rendered |
| File size | Roughly unchanged | Hidden content is still stored |
| Every page | Cropped by the same margin | One even trim across the document |
Cropping sets the visible window rather than destroying content, so it is lossless and reversible — but it is not redaction. Anything you crop away can still be recovered from the file, so never use it to hide sensitive information.
Frequently asked questions
How does cropping a PDF work here?+
It trims an even margin off all four sides of every page by shrinking the page box (both the media box and crop box). The visible page becomes smaller, cutting whitespace or scan borders, and the change applies to the whole document.
Are my PDFs uploaded?+
No. The crop is applied entirely in your browser with pdf-lib, so the PDF never leaves your device — safe for confidential files, and it works offline once loaded.
Can I crop each page differently?+
This tool trims the same margin from every page, which is the common case for removing consistent whitespace or borders. Pages with different sizes are each trimmed by the same amount from their own edges.
Does cropping delete the trimmed content?+
It hides it by shrinking the page box, so viewers show and print the smaller page. The underlying content outside the box isn't rendered. For a hard removal of content, redaction tools are the right choice.
Is it free?+
Yes — no signup, no watermark. It's ad-supported and runs entirely in your browser.
