AVIF

“it's smaller than WEBP in the normal modes (s6; s>=7 switches to real-time mode which sucks and s3 takes centuries”

“they tend to use webp and avif, which are much smaller for the same quality”

“they think that people are using 3G but with a computer with a fast CPU (to decode AVIF”

“AVIF is also free, and since it's literally the I-frame of an AV1 stream, it can be decoded directly on the GPU”

“Every single webpage I've seen with webp / avif images also had autoplaying videos, intrusive ads, and megabytes of JS”

“the beautiful highlights on the car have been erased and replaced with something plausible”

“you can zoom in on an AVIF so for actual animated images it wins on that front”

“avif was even better compression for some cases, but seems to take a long time to generate, and less widespread browser support.”

“Especially for animated images. Comparing webp or avif sizes to gif is easily a factor of five to ten when animated.”

“AVIF is vastly more efficient at any fidelity target with reasonably modern encoders”

“the very slow encode speed made it unsuitable without paying for a larger server”

“I would say webp/jxl/avif is anti-general compute, since they require very recent software.”

“avif is typically significantly better at small files sizes where loading speed (or saving data) is the priority”

“AVIF beats jpg and png just about on every metric when compression is required”

“I don't like the lack of consistency and some of the artifacts to the point where I'd prefer not using progressive encoding”

“the demo proves that AVIF can deliver a usable image with up to 3x as fewer bytes as JXL”

“AVIF does seem to have at least a couple of downsides compared to JXL like max 12-bit depth”

“IMO animated picture formats like .avifs are very backwards and don't add much”

“It seems quite limited compared to the JPEG XL ability to truncate the bitstream anywhere”

“I changed all my .jpg files to .avif a few years ago. The benefit I get is much more than 20%.”

“I believe AVIF requires tiling in order to parallelize, which causes artifacts at tile boundaries.”

“AVIF does well across the board, so if you feel compelled to pick a single format to use, AVIF would be a better choice”

“any hardware decoding support AVIF will get is likely to be restrained to common video scenarios”

“AVIF's "progressive decoding" serves no technical benefit and is only a minor ergonomic benefit”

“AVIF is royalty-free, with open-source implementations not developed by Google.”

“AVIF is better but only equal or worse at decent, visually transparent bitrates.”

“The compression ratios with AVIF are ridiculous compared to older formats.”

“There is also AVIF format which is newer and better but it needs to still mature a bit with better support/compatability.”

“smaller file size, transparency support and circumventing autoplay restrictions on Safari”

“AV1/AVIF is better in every way but in the real world it's too taxing on ordinary hardware.”

“Sadly a folder full of avif files will make pretty much any consumer cpu in existence chug like mad”

“It's widely supported by browsers, and rivals JPEG XL in being the best lossy image format.”

“I'm guessing the better suggestion would be to use apng or animated avif if you are looking for a proper gif alternative.”

“Way wider browser adoption, potential to evolve together with AV#, since it's using a container format”

“Smaller AVIF images look ok, but the equivalently sized JXL images look way worse, so I gladly serve AVIF.”

“no its not remotely competitive with JXL, the only benchmarks it trades blows are ones with laughably low quality settings”

“AVIF is significantly better than JPEG/WebP in compression efficiency at comparable quality”

“There's no particular reason for an image format based on video codec keyframes to ever support a lot of the advanced features”

“AVIF only comes out as superior at extreme compression ratios at much lower bit rates than are typically used for web images”

“it looks like the AVIF just made up some probable-looking blobs of light that don't look that much like the original”
