Interestingly though, there's a been a concerted effort to squeeze every bit of optimization out of the existing formats: JPEG has MOZJpeg, Guetzli, JPEGOptim, and Jpegtran. It may take some similar act of corporate benevolence to bring a successor to JPEG. It took Cisco buying and distributing the Mp4 patent for free to move MP4 to the accepted video formation for Microsoft, Apple, Google, and Mozilla. We're starting to see future image formats like Google with WebP, and Apple with JPEG2000 and HEIC, and Safari allowing inline MP4s to be treated as images but for the past 10 years, much of the action in image compression has been trying to squeeze out ever last single byte out of the existing formats, almost entirely for JPEG and PNG (and SVG but that's a different story) A lot of the slow movement of web formats has to do with the W3c. These are intermediate formats that require specialized software to view/edit and converted when distributed beyond professional means (sans EPS). You may occasionally PSDs or EPS files, or photography formats like DNG or standard-free RAW, but those fall into the same category as video codecs like ProRez, DNxHD, Cineform. However, static images haven't had the wide range of codecs (most formats are lossless proprietary files used by various image editors) and have been almost entirely relegated to five formats, SVG, BMP, PNG, JPEG and GIF for distribution. ![]() Audio has had a similar vector from LMA4:1, Mpeg, MP2, Mp3, ACC, Ogg, AC3, DTS to name a few. This doesn't even cover the other formats, VP8, VP9, Ogg Vorbis, DIVX, 3IVX, Sorenson, Real Media and the many others that occurred the past 30 years which all have had variations of mainstream success. Each iteration with the ultimate goal of improving video quality with at lower bit rates. Over the years, codecs have improved remarkably, especially in the realm of video: For example: H.261 (1984, 1988) -> MPEG-1 (1988-1991) -> MPEG2 aka H.263 (1996-2015) ->MPEG4 aka H.264 (1999-current) -> High Efficiency Video Coding (HEVC) aka H.265 or MPEG (2015 - current). I recently decided to finally try out Squash by Realmac Software. I tend to be a little obsessive, using modern formats (WebP, JPEG 2000) and testing out avant-garde projects like Guetzli by Google. For years I've leaned on ImageOptim as my go-to for image optimization. ![]()
