What happens to your image?
AVIF can create compact images and supports transparency. The server decodes the uploaded still image, encodes AVIF, and reports the actual output size.
Check AVIF support in the app where you will use the file. Keep your original image until you compare the result.
Upload, process, save.
- Choose a supported still image from your device.
- Set quality or width when the tool offers a control.
- Process the image, compare the actual sizes, and save the result.
No account is required. Animated, broken and oversized images are rejected.
