Compress Images Online Free — No Software Required
Large image files slow down websites, fill up storage, and exceed email limits. Our free online image compressor reduces JPG, PNG, and WebP file sizes dramatically — often by 60–80% — without any visible quality loss. Everything happens inside your browser, so your images stay completely private.
Unlike desktop tools like Photoshop or online services that upload your files to a server, our compressor uses the browser's built-in Canvas API to process images locally. No account, no waiting, no privacy risk.
JPEG vs WebP vs PNG — Which Format to Choose?
The right output format depends on your use case:
- JPEG — Best for photos. Achieves 50–80% size reduction with minimal quality loss. Universal compatibility.
- WebP — Modern format. Equal or better quality than JPEG at smaller file sizes. Ideal for web use. Supported by all modern browsers.
- PNG — Lossless. Best for screenshots, logos, text, and graphics where quality must be perfect. Larger file sizes.
