The Image Compressor reduces the file size of JPEG, PNG, and WebP images directly in your browser without uploading them to any external server. Large image files are one of the most common causes of slow web page load times — studies consistently show that images account for the majority of page weight on the average website. This tool uses the browser's Canvas API to re-encode images at a lower quality setting, producing significantly smaller files while maintaining visually acceptable quality. You can adjust the compression quality slider to find the optimal balance between file size and image sharpness for your use case. A side-by-side preview lets you compare the original and compressed versions before downloading. Because all processing happens locally, your images remain completely private — ideal for sensitive photos or confidential documents.
Drag and drop your image file onto the upload area or click to browse and select one. Adjust the quality slider to control the compression level — lower values produce smaller files with more visible quality loss. Preview the result, then click Download to save the compressed image to your device.
