In the question“What are the best alternatives and lossless compressors for JPEG?” WEBP - Format is ranked 1st while BPG - Format is ranked 2nd. The most important reason people chose WEBP - Format is:

Question Ranking
Pros
Pro Same image quality, half the size
BPG is able to produce the same image quality as JPEG but at half the size. This is simply because is uses a newer codec, x265 which is the open-source implementation of HEVC/H.265.
Pro Open source
BPG is an open source implementation which only took a few months to be created. It is not created by some international standardization body (like ITU or ISO), which take several years to create and update standards.
Since it's open source, changes can be proposed at any time, and if they benefit the project, they are merged into the main branch. This ensures that the standard is always up to date and that fixes can come quickly.
Pro More bits per color channel
BPG is able to render more bits per color channel compared to JPEG. 14 bits vs just 8 bits.
Pro Alpha channel
BPG has an alpha channel, which adds transparency to BPG images if needed.
Pro Same quality for about half the size
Images saved in the WebP format have roughly the same quality as a JPEG image at about half the size.
Cons
Con is an underground image format...
is not suported by actual profesional viewers or editors
Con No native support in browsers
No browsers support native decoding of this format yet. It should be noted though, that there's a JavaScript implementation of the decoder which can execute and decode BPG files.
Con Garbage format
Ultra compression algorithm destroys any traces of quality...is another google emanation...is not a copy of an image not even a preview or thumb is just a luke-like representation of the original image...destroys color profile and outlines look horrible... avoid this if you have respect for quality.
Con Not widely supported
Only has native support in Chrome and Opera.
