Resize image to % of its original dimensions.
Compress JPEG images by adjusting quality (1–100%) to find the sweet spot between file size and visual quality. PNG images are losslessly optimised to remove unnecessary metadata.
Instantly see the original file size versus compressed file size and the percentage reduction achieved. Helps you confirm compression is effective before downloading.
Your images never leave your device. Compression is performed using the HTML5 Canvas API entirely in the browser — ideal for confidential photos and documents.
For web images, a quality setting of 75–85% typically provides a good balance — file sizes are 50–70% smaller than the original with minimal visible quality degradation. For thumbnail images or backgrounds, 60–70% works well. For portfolio or product photography where quality is paramount, use 85–95%.
Large image files are the most common cause of slow page load times. Google uses page speed as a ranking factor (Core Web Vitals — LCP). Compressed images reduce bandwidth usage, lower hosting costs, and improve user experience — especially for visitors on mobile connections. Aim for image files under 200 KB for web use.
No. This tool performs compression by reducing the quality or optimising the encoding — the pixel dimensions (width × height) remain the same. To resize (change dimensions), use the Image Editor tool which supports resizing and cropping.
