Compress Image to 400KB

Some platforms limit image uploads to 400KB. This is sufficient for detailed photographs at web resolution but requires compression for high-resolution camera images or screenshots from large monitors.

How It Works

1
Drop your image

Drag and drop any JPEG, PNG, or WebP image. No signup required.

2
Set target: 400KB

The compressor automatically adjusts quality to get your file under 400KB while preserving as much visual quality as possible.

3
Download the result

Your compressed image is ready. Check the before/after comparison to verify quality.

Your images never leave your browser. All processing happens locally on your device — nothing is uploaded to any server.
