A : JPG, JPEG, PNG, GIF, WebP, AVIF and HEIC. Output as JPG, WebP or PNG.
A : No. Compression runs in your browser: your images never leave your device.
It could be helpful to reduce the weight of images, in order to use it on a website for example. The webpage will load faster, and it saves bandwidth. Or for example, just before sending an email you can compress image, or just before sharing it on a social network. JPG has no transparency: choose WebP to keep it. Animated GIFs are converted to a still image.
Which compression level and format should I choose?
Every image is a trade-off between weight and detail. The default level removes a large part of the weight while keeping the picture clean on screen. Move the slider, then click the thumbnail of a result to compare the original and the compressed image with a sliding before/after view.
JPG, WebP or PNG?
- JPG: best for photos and works everywhere. It has no transparency: transparent areas become white.
- WebP: usually lighter than JPG at similar quality, and it keeps transparency. A good choice for websites.
- PNG: best for logos, screenshots, icons and graphics with sharp edges or transparency. The level reduces the number of colours; at 0% the result is lossless.
Resize before you compress
A phone photo is often 4000 pixels wide, far more than a web page or an email needs. Open More options and set a maximum width (1920 px for full-width images, 1280 px or less for blog pictures). Reducing the dimensions usually saves more weight than a higher compression level, and the image stays sharp.
Need a specific file size?
Type a target size in KB (for example 200) and the tool looks for the best quality that fits, reducing the dimensions only if needed. This is handy for forms and applications with an upload limit.
Your images stay on your device
Compression runs in your browser: nothing is uploaded to a server. iPhone HEIC photos are supported too, and files that cannot be made smaller are returned unchanged instead of heavier.
