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.
