AVIF - Advanced options for image conversion

Custom

Quality
The image quality of avif can be adjusted. The higher the value, the higher the quality. The default value is 86.

Compression strength
You can adjust the compression quality, ranging from 1 to 8. The higher the value, the better the compression effect, but also the longer it takes. The default value is 4.
We recommend using 4 to strike a balance between compression efficiency and time consumption.

From the lowest 1 to the highest 8, there are obvious differences in processing speed, you can learn more about it through the avif compression strength test table below.

Optimal
Automatically set the image quality to 90 and the compression strength to 4 to convert avif, so that the output avif image quality and image file size achieve the best balance.

Lossless
Automatically set the image quality to 100 and the compression strength to 4 to convert avif, so that the output avif picture retains all image details.
