Mozilla has announced a new JPEG compression library that attempts to make JPEG images smaller without changing the file format.

Damn -- there's no binary version. It's just source code. 2021 EDIT: You can get this as part of a suite of JPEG compression tools in FileOptimizer, which is portable.

Whatever the case, it's still great news. I have probably 1,000 images on my drive and if I can cut ~10% each of those, that's no small achievement. Kudos to Mozilla for going this route, although I do hope someone comes up with a full replacement that isn't patent encumbered.

Well Google is again trying to own the internet and has come up with WebP but just like WebM I suspect there are patent issues in there. That and no new format is every going to replace old ones any time soon just because of the human Psyche. MP3 is god knows how old but is still the main format for digital audio.

I can't speak to WebM but WebP wasn't considered by many to be an adequate replacement, though it's great for thumbnails: https://en.wikipedia.org/wiki/WebP#Criticism Although it's patent status is supposedly in the clear.

That's pretty old though and was about V8 but believe we are now on V9

WebP is based on VP8, and AFAIK there are no plans to switch to VP9.

Google has also put out an open JPEG encoder "Guetzli". Unlike mozjpeg, this is a high-compression, lossy, and very slow tool for high-usage web images. In other words, use mozjpeg (contained in FileOptimizer) for any JPEGs you want to shrink and Guetzli on frequently downloaded images.

Guetzli: Tried it, AV blocked execution of Guetzli as it reports "trojan detected" so haven't been able to actually test it yet.

Any experiences with BPG (https://en.wikipedia.org/wiki/Better_Portable_Graphics)?

Unfortunately there's no support for the format beyond the developer's tool and this came out back in 2014. Not even XnView and Irfanview, which support 100s of formats.

I think the lack of solutions on this topic is ultimately what drove Mozilla to put out an enhanced JPEG compression tool.

Mozilla is now planning to support the WebP image format in Firefox starting from first half of 2019: https://www.cnet.com/news/firefox-to-su ... aster-web/

Interesting. It's probably one of those things where they don't want to avoid a format that almost everyone else covers. I don't do a lot of webdev work anymore but wouldn't have much to do with the format if I was. I just don't understand the use case for anything other than thumbnails.
