An image compressor is an online tool that reduces the file size of images without significantly affecting visual quality. It helps speed up websites, save storage space, and reduce bandwidth usage while maintaining good image quality. Our tool uses advanced algorithms to achieve optimal compression ratios.

Depending on the original image and quality settings, you can typically reduce file size by 30-80%. JPEG images often see the biggest reduction (50-80%), while PNG images with transparency may have more modest savings (20-40%). WebP format typically offers the best compression ratios.

Since processing happens in your browser, the limit depends on your device's memory. Most modern devices can handle images up to 20-50MB each. For best performance, we recommend images under 20MB. You can process multiple images in a single batch.

WebP is a modern image format developed by Google that offers superior compression compared to JPEG and PNG. It supports both lossy and lossless compression, transparency, and animation. WebP files are typically 25-35% smaller than equivalent JPEG files. We recommend WebP for web use if your audience uses modern browsers.
