Compress images online — single or batch

Shrink JPG, PNG, and WebP one at a time or in bulk. No visible quality loss, no uploads — your photos never leave your browser.

A free, in-browser image compressor that shrinks JPG, PNG, and WebP files to a smaller size while keeping them sharp. Compression runs entirely on your device, so your photos never leave your browser. No signup, no watermark.

1. Upload your images — Drag and drop your photos or click to select them. You can compress up to 5 images at once for free, or up to 15 with premium.
2. Adjust the quality slider — Move the quality slider to balance file size against image detail. Lower quality means a smaller file; higher quality keeps more detail.
3. Check the before and after size — Zebra shows the original and compressed file size for each photo, so you can confirm how much space you saved before downloading.
4. Download your compressed images — Download a single compressed image directly, or grab all of them at once as a ZIP file.
