How to Use the Image Compressor

Choose an image (JPG, PNG or WebP), adjust the compression quality and scale, and the tool instantly shows the file size before and after. Click "Download Compressed Image" to save it.

The quality setting controls encoding detail — 70-85 is usually visually lossless while greatly reducing file size. The scale can further reduce resolution, ideal for web pages, email or social posts.

All processing happens locally in your browser. Your image is never uploaded to any server, keeping your privacy intact.
