Make JPG, PNG and WebP images smaller on your computer
Quick answer
Drop images into Toolfox → Image Compressor and click Compress. JPEG and WebP are re-encoded at the quality you choose; PNG is optimized losslessly. You see the size before and after, and if a file wouldn't get smaller, nothing is written. It runs entirely on your computer (Mac, Windows or Linux). Files are never uploaded.
How to do it
- Open Image Compressor and drop JPG, PNG or WebP files.
- Set JPEG/WebP quality (70–85 is usually invisible on screen).
- Click Compress. Results show “−63%”-style savings.
- Originals are kept; copies are named photo-compressed.jpg.
Options you can set
- JPEG quality
- PNG optimization effort
- Remove PNG text metadata
- WebP mode
- WebP quality
- Skip files that wouldn't get smaller
Good to know
- JPEG and lossy WebP re-encode the image and permanently discard some detail.
- PNG optimization is lossless; some PNGs are already optimal and won't shrink.
- Re-encoding removes EXIF/XMP metadata (including GPS). The color profile is kept where the format allows.
