What is Image Compressor?
The Image Compressor is a free online tool that reduces the file size of JPG, PNG, and WebP images while preserving visual quality, all processed locally in your browser with no server uploads required. Large image files are one of the biggest causes of slow website load times, failed email attachments, and excessive cloud storage usage. Compressing images before uploading them to your website, social media, or cloud storage can reduce file sizes by 50-80% with little to no visible quality loss. This tool gives you control over the compression quality level so you can find the perfect balance between file size and image quality for your specific use case. The before and after file size comparison lets you see exactly how much space you are saving before downloading the compressed result.
