Compress images in your browser by adjusting quality, output format, and max dimensions to reduce file size.
Lower quality and smaller max width reduce file size. JPEG is best for photos; WebP and AVIF often produce smaller files when your browser supports them. Images are never uploaded.
Compress images in your browser by adjusting quality, output format, and max dimensions to reduce file size. This Image Compressor is part of our free image tools collection on freetoolstouse. It runs entirely in your browser, so your files and inputs stay on your device unless the tool explicitly performs a network check (for example DNS or SSL lookups). There is no signup, no watermark, and no usage cap. Use it whenever you need a fast, accurate result without installing software.
