Compress images by up to 80% without visible quality loss. 100% free, works in your browser.
Supports JPEG, PNG, WebP — up to 50MB each
Compress your JPEG, PNG, and WebP images directly in your browser. Our tool uses advanced canvas-based compression to reduce file sizes by up to 80% while maintaining visual quality. Perfect for optimizing images for websites, emails, and social media.
Unlike other tools, ToolBox Image Compressor processes everything locally in your browser. Your images are never uploaded to any server, ensuring complete privacy. There are no file size limits, no watermarks, and no daily usage caps.
Select your images, adjust the quality slider to balance between file size and visual quality, and hit compress. The tool uses the HTML5 Canvas API to re-encode your images at the specified quality level. WebP format typically provides the best compression ratios.
