Free tool

Image Compressor

Shrink images up to 90% without visible quality loss.

Large images slow down websites, eat up phone storage, and bounce off email attachment limits. Our free tool to compress image online shrinks your JPG, PNG, and WebP files right in your browser, dramatically smaller file sizes with quality differences you can barely see. The tool above shows before-and-after sizes for every image, so you know exactly what you saved. A single unoptimised hero image can add seconds to a page’s load time, and every second of delay costs real visitors. Compressing is the single fastest performance win for most websites.

It’s completely free with no sign-up and no daily caps, and, this is the important part, your images never leave your device. Unlike most compressors, nothing is uploaded to a server; all the compression happens locally in your browser. Bloggers, designers, and anyone emailing photos will love it. Pair it with our color palette generator for design work, or browse all free tools in the Savozi collection.

Private by design

Most online compressors upload your photos to their servers, ours doesn’t. The Image Compressor processes every pixel locally in your browser, so personal photos, client work, and screenshots never travel over the internet. Nothing is stored and nothing is analysed. Free forever, and genuinely private. Photographers sharing client galleries and businesses handling product shots can compress with confidence that their images never touch a third-party server. Smaller files also mean faster page loads and happier visitors.
