Image Compressor
Local in-browser compression
Compress JPG/PNG images entirely in your browser: drop a file, choose a quality slider, and compare sizes in a preview — images never leave your computer. Ideal before uploads.
How to use
- Select a JPG/PNG image;
- Drag the quality slider (60–80 is usually the sweet spot);
- Click "Compress" and compare sizes in the preview;
- Right-click (or long-press) the preview to save the result.
FAQ
Are images uploaded?No — compression happens via Canvas on your device and works offline.
Why is output always JPG?JPG gives the best compression for photographic images; for transparency, use a PNG-capable tool.
