How to compress an image
- Pick a quality level. 70–80% is usually indistinguishable from the original.
- Optionally set a max width to shrink large photos (1920px is great for the web).
- Drop your images in. Compression happens instantly on your device.
Frequently asked questions
Are my images uploaded anywhere?
No. Compression uses your browser's built-in image engine, so files never leave your computer.
Which format makes the smallest files?
WebP is typically 25–35% smaller than JPG at the same visual quality and is supported by all modern browsers.
Why did my PNG get bigger?
PNG is lossless, so screenshots and graphics may not shrink much. Switch to WebP or JPG for much smaller files.
