Image Compressor
Reduce JPG, PNG and WebP file size by quality or an exact target — in batches.
75%
Smart mode keeps screenshots and logos as PNG (palette + lossless optimization) and sends photos to JPEG/WebP — the smaller result wins, and files that can’t shrink are kept as-is.
PNG is optimized locally with lossless re-deflation and an optional 256-color palette; the quality slider doesn’t apply.
Transparent PNGs are flattened onto a white background when saved as JPEG.
Your images never leave this device.
