Upload an image to compress it
Upload your image
Click "Choose Image" and select a JPEG, PNG, or WebP file from your computer.
Adjust quality
Use the quality slider to balance file size and visual quality. 80% is a good starting point for product images — you get ~60% size reduction with no visible loss.
Check before/after sizes
The tool shows original and compressed file sizes in real time so you can find the ideal quality setting.
Download the compressed image
Click "Compress & Download" to save the optimized image directly to your computer.
