Background Removal#
imgcompress includes a local AI model that removes image backgrounds entirely on your server's hardware. No cloud, no external API.
To preserve transparency, choose AVIF or PNG as your output format. JPEG does not support transparency.
How to use it#
- Select AVIF or PNG as the output format.
- Toggle the Remove Background switch on.
- Convert as normal.

Example#
Here is what the AI background removal looks like on a landscape photo:
| Original | Background removed |
|---|---|
 Original landscape with sunset |  Landscape with background removed |
Target a Specific File Size#

Storage Management#
imgcompress stores processed files on the server for easy re-download. You can manage them from the Storage panel.

If you don't want users to see processed files, add DISABLE_STORAGE_MANAGEMENT=true to the environment: section of your docker-compose.yml. → See the docker-compose setup
Privacy#
imgcompress is self-hosted. Your files never leave your own server and nothing is sent to any external service. Only you (and anyone you give access to your server) can see your uploaded files. See Privacy & Safety for details.
