Compress Images Online — Reduce File Size Instantly
Reduce image file size with adjustable quality.
About this tool
Reduce image file sizes without noticeable quality loss. Adjust compression levels to find the perfect balance between size and quality. Supports JPEG, PNG, and WebP.
Why Compress Images?
Large images slow down websites, increase storage costs, and eat mobile data. The Image Compressor reduces file sizes by up to 80% while keeping visual quality indistinguishable from the original — ideal for web publishing, email attachments, and social media uploads.
Quality vs. Size Trade-off
Use the quality slider to find your ideal balance. Settings above 80% are nearly indistinguishable from the original. For thumbnails and previews, settings between 30–50% dramatically reduce file size with acceptable quality. The side-by-side preview lets you judge before downloading.
