Description
Mask data Adobe Camera Raw and Lightroom save beside a photo (starts ACR). It shares the .acr extension with the DICOM image format, and no converter here reads it yet.
Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files.
MIME Type
application/octet-stream
image/vnd.mozilla.apng
