Compress Image
Shrink your image's file size with barely any visible quality loss. Everything happens in your browser — nothing is uploaded.
PNG is lossless and ignores the quality slider — only "max width" changes its size.
How Much Can Image Compression Save?
Most photos taken on phones or downloaded from the web carry far more data than a browser or website actually needs. Lowering quality to around 70–80% and capping the width at 1920px typically cuts file size by 50–80% with almost no visible difference to the eye.
JPEG, WebP, or PNG — What Should I Pick?
JPEG works well for most photos and gives you full control over the quality slider. WebP usually produces the smallest file at the same visual quality and is supported by virtually all modern browsers. PNG is lossless, so it ignores the quality setting — only useful when you need a transparent background or perfectly sharp edges.
Is This Safe for Private Photos?
Yes — compression happens entirely on your device using the browser's Canvas API. Your image is never uploaded, so this is safe to use even for personal or confidential photos.
