Image Compression

We support JPEG, PNG, WebP, and AVIF formats for both input and output. You can convert between formats during compression.

It depends on the image and settings. Photos often compress more than graphics. You'll see the result before downloading.

Lossless keeps image data intact while reducing size. Lossy can reduce size further by removing some detail — usually with minimal visible impact at sensible settings.

Background Removal

We use advanced AI models to detect and separate the foreground subject from the background. The result is a transparent PNG that you can use anywhere.

Clear subjects, good lighting, and strong contrast with the background. Complex scenes may require a second try or different settings.
