After 20 years, PNG is back with renewed vigor! A new PNG spec was just released.

      The title is hyperbole. PNG is lagging behind modern lossless formats in terms of new features.
      This doesn’t mean it’s a bad format or that it shouldn’t be used. In fact, it should still be the default unless you need something it doesn’t support or really need to reduce file size.

        I disagree. It is wasteful (we’re talking ~30% savings with lossless WebP or JPEG-XL) and widely misused, which matters at the massive scale of the Internet with technically inexperienced people making up plenty of those images.

          Congratulations, your noob user is now using JPEG-XL. It’s not working on old devices, or any mainstream browser besides Safari. The less mature library also has a bug that allows for RCE and now everyone is running a cryptominer.

          Now you say, but webp is supported everywhere, so let’s go with that. Now the noob is using wepb for a bunch of rasterised vector graphics with 4 or 5 flat colors, and he’s wasting more disk space than before.

          So I repeat, if you need one size fits all, PNG is better, it works everywhere, and it’s even more efficient in cases where lossless graphics matter the most.

            Now the noob is using wepb for a bunch of rasterised vector graphics with 4 or 5 flat colors, and he’s wasting more disk space than before.

            I just tested with this image:

            Default GIMP WebP export settings (90% quality): 88.8 kB

            Lossless WebP mode: 85.6 kB

            Default GIMP PNG export settings (compression level 9): 189.8 kB

            So I don’t trust this claim unless you have some evidence.

        I rather disagree. I’ve switched to lossless WebP for all my needs. There are practically no drawbacks and I get a smaller file.
