Optimage 3.0 - Automatic image compression that actually works

@fede_nelli1 In short, lossless compression is 5-15% better, it's more careful with Exif, color profiles and sensitive metadata. Lossy compression is better or worse depending on the image content. The difference is visual quality. Optimage has not failed yet in the tests, while ImageOptim failed in over 50% of cases. Optimage uses maximum error while ImageOptim uses average error for image quality assessment, meaning local error can be anything, colors negated, etc. You can find the detailed comparison on the website, the link is attached above. Also, Optimage can compress more formats including WebP, HEIC, APNG, MP4, WebM, ICO, ICNS - over 20 in total, with high-quality resizing and conversion, and that's not all.

@ange_du_soir Other platforms will come eventually. That was the goal since the beginning but I had to choose one to perfect. There is some progress, but it is too early to say when.

@ange_du_soir @vmdanilov Good news, I'd love to pick this up but mainly need it for PC. Good image compression apps in that space are slim pickings. You'd definitely stand out!

@ben_roe ImageOptim does not provide automatic image compression because image quality is completely unpredictable. There is a huge gap between automatic and semi-automatic with manual tweaking.

@mgganesh You can use Transmit Disk to connect to your server and optimize images in the mounted folder. I have some ideas on how to make it even easier.

@jshwrnr i am also using imageoptim, what about the quality? Does it decrease the quality?

@dj_chris_purple No, but it's possible. I plan to make a universal CLI tool first.

@adamhuet Can you share the image, so I can investigate and fix if there is an issue? You can find the email on the website. There are a number of cases when it may happen, e.g. color conversion. In that case there are two choices, either leave the image without the requested modifications or modify it as requested. Optimage chooses the latter for critical formats because they may contain sensitive metadata.

@brandon_mcconnell I plan to build a solution for this, starting with a universal CLI tool.

@jemshit_i There's a detailed comparison on the website, the link is attached above. In short, Optimage provides comparable compression ratios and does not cause noticeable artifacts.

@cristianmoisei They produce noticeable artifacts. You can see the comparison on the website. The link is attached above.

@vmdanilov Fair enough, I'd be happy happy to switch to this if the compression algorithm delivers more savings with no noticeable artefacts, especially colour differences. But I still think saying that this app 'actually works' is a bit of an overstatement. The others work too, quite well. Your claim is that this app works better.

@cristianmoisei It's about automatic image compression that 'actually works' when image quality is consistent. ImageOptim, TinyJPG, JPEGMini and most other tools rely on average not maximum error, meaning a part of your image can be destroyed beyond recognition.

@eightyeighteigh Yes, other platforms are in the works.
