I make this image public in the AVIF format (can be opened in the latest IrfanView, Chrome and Firefox): Link to AVIF in Google Drive
The AVIF image compression (in the HEIF container) is a very promising format as it provides good image quality in a very small package and is (in comparison to HEIC) free of any licenses. I hope Flickr as well as Google and Microsoft products will soon have full support for this innovation.
Besides the high compression efficiency the big advantage over JPEG is that a color depth per channel of 10 and even 12 bit is supported.
This sample is generated using the avifenc.exe command line encoder for windows.
I used this parameters:
avifenc.exe --cicp 2/2/1 -r limited -y 420 -j 6 --min 30 --max 40 --minalpha 30 --maxalpha 40 in.png out.avif
The result is:
- 6 threads used (for my 6 CPU cores)
- to colorspace YUV420 (422 and 444 is not supported by the Windows AV1 extension)
- 12 bit per channel
