A PDF with excessive white space around the edges — a scanned page, an exported slide, a document with wide margins — can be hard to read on a small screen or wastes space when printed multiple-up. This tool trims a fixed margin from each edge of every page, in millimeters, and gives you back a smaller, tighter file.
How it works
Upload your PDF and enter how much to crop from the top, right, bottom, and left edges (in millimeters) — you can crop different amounts from each side. The tool trims every page by exactly those margins and gives you a single cropped file to download.
- Upload a PDF file.
- Enter the margins (in mm) to crop from each edge.
- Generate and download the cropped PDF.
Examples
Trimming a scanned document's wide margins
A scanned document with 25mm of blank margin on every side is cropped down by 20mm on each edge, leaving a tighter, more content-focused page.
Cropping only the top margin
A document with an unwanted header area is cropped by setting only the top margin, leaving the other three edges untouched (by entering 0).
Who should use it
- Trimming excessive white space from a scanned document.
- Removing an unwanted header or footer area by cropping a single edge.
Industry applications
- Document scanning and digitization
- Print and publishing preparation
Advantages
- Independent control over all four margins.
- Produces a genuinely smaller page, not just a visual crop.
- No account, subscription or watermark.
Limitations
- Requires knowing the margin sizes in millimeters — no visual crop-and-drag preview.
Common mistakes to avoid
- Entering margins so large that little or no content remains on the page.
- Cropping without first checking whether important content sits close to the page edge.
Best practices
- Check a sample page's content placement before choosing margin values for a whole document.
- Crop conservatively first, and re-run with larger margins if there's still excess white space.
Tips
- Check both the first and last page of a multi-page document before finalizing margin values, since layouts can vary.
- Start with smaller margin values and increase gradually to avoid over-cropping content.
