Self-hosted. Your files never leave your network.

Frequently asked questions
- Does cropping permanently remove content outside the margins?
- Cropping adjusts the visible area of each page. Content outside the crop box may still exist in the file data but will not be visible or printed. Processing runs entirely on your local server.
- Can I set different margins for each side?
- Yes. You can specify independent crop values for the top, bottom, left, and right edges. The same margins are applied uniformly to all pages. Files are processed on your self-hosted instance.
- Will text and images inside the crop area be preserved?
- Yes. Everything within the crop boundaries is fully preserved including text, images, annotations, and links. Your documents never leave your own network during processing.
