On-the-fly image processing updates
{image processing}
- Now we choose JPEG format for images with totally opaque alpha channel if
-/format/auto/is used and WebP is not available. - When the original image is a low-quality JPEG and we need to re-encode it to another format (WebP for instance), we limit the output image’s quality by the original image quality approximation.
- When the original image is a low-quality JPEG and we need to encode it as JPEG, we reduce the output image’s quality more accurate than before.
- Face detection for small sized faces is improved.

File info response includes a value of a perceptual hash calculated using pixel contents of an image. Perceptual hashing is a common fingerprinting technique to quickly compare images and find duplicates or similar images.
