Shrink Images Instantly — Up to 90% Smaller, Zero Quality Compromise

Typically 50–90% size reduction depending on:

• Original quality & format
• Chosen quality slider (75% is usually perfect balance)
• Whether you resize (max dimension)

WebP output almost always gives the best results.

100% private — everything happens in your browser.

• No images are ever uploaded to any server
• No tracking of what you compress
• No logs or storage of your files

Completely client-side using Canvas & JSZip.

WebP usually gives:

• 25–35% smaller files than JPEG at same visual quality
• Transparency support like PNG — but much smaller
• Modern browsers support it natively (Chrome, Edge, Firefox, Safari 14+)

Use JPEG if you need maximum compatibility with very old devices.

Currently supports static images only (JPG, PNG, WebP, etc.).

Animated GIFs and vector SVGs are not yet supported — coming soon!

First time may take 2–8 seconds because browser is:

• Loading Web Workers / Canvas
• Initializing JSZip library

Subsequent compressions are instant.
