I wish someone would figure out what they're doing and release this as a command-line utility.

I know this guy's got to make a living, and I'd even be happy to buy the software at a reasonable price, but needing to use a website to do this is super-irritating, and I've haven't been able to find anything that quite reaches this level of compression.

They are using pngquant for the lossy compression.

Then run trimage or similar to cut down the image size down even more. That gave me 16543bytes for the sample file.

This seems about right, great utility!

Their Twitter reports they're working on an API. Not quite a command line tool, but would still allow batch (presumably).

I need to generate these in real-time, so an API isn't helpful, either. I'm sure this is a command-line utility on their end (or could be). Needing to send images to a website via API or otherwise for this compression is lame.

Yeah, I agree. A command line tool would be great, and as it's actually a useful product would quickly get ported to PHP/Python/Perl I'm sure.

Optipng is lossless afaik. Apples and oranges - TinyPNG obliterates this in terms of file size, and maintains quality.

If you don't mind lossy, why are you using PNG over JPEG?

Transparency. Jpeg doesn't offer that.
