Image Compress

Compress images directly in your browser. Reduce file size by adjusting quality and format.

Why Image Compression is Needed

Images account for a large portion of web page loading time. Reducing image file size shortens page load times and reduces data usage on mobile. Image optimization is also a key factor in Google's Core Web Vitals evaluation.

WebP format provides 25-35% smaller file sizes than JPEG on average with virtually no visual quality difference. Since most modern browsers support WebP, using WebP format for web images is recommended.
