Trim the top, bottom, left, and right margins of PDF pages in millimeters (by adjusting the CropBox and MediaBox) and save a margin-free document. It's great for removing the excessive white space on scans or filling a tablet screen for reading.
How to use
- Load a PDF file to see a preview based on the first page.
- Enter the margin for all four sides equally, or each one individually in millimeters.
- Check the blue area (the part that remains) in the preview.
- Click "Trim and Save" to download the cropped PDF.
FAQ
- Is the cropped content deleted completely?
- It adjusts both the CropBox and MediaBox so the trimmed area is hidden on screen and in print. If you're worried about losing the original, work on a copy.
- Is the same margin applied to every page?
- Yes. The millimeter values you enter are applied equally to each side of every page, and it handles pages safely even when they differ in size.
- Are my files uploaded to a server?
- No. Margin calculations and saving all happen in your browser, and your files are never sent to a server.
