Not a serious solution

Negative Comment by cmoi
about RIOT - Radical Image Optimization Tool Jul 2016

Install OpenCandy adware - not serious from the developer. Ban this kind of software.

And thanks to Alternatioveto.net, I found very good alternatives like XnConvert: lightly more complex interface but much more options and features !

Portable version is clean

Hi, good news: the portable version seems clean from OpenCandy adware (VirusTotal)
You can find it here.

Riot is also included in tools like IrfanView and Gimp. I think they don't have OpenCandy too. The 'Extended Plugin' installer is infected too, though!

I did some random comparison tests between Riot and Caesium, and found out that Caesium did the job slightly better. I will switch and ban this OpenCandy tool. Thanks AlternativeTo!

Trying to install RIOT, I receive a warning from Malwarebytes about installation of potentially unwanted progams (PUP). Beware.

Note on plugin version

Alpha transparency in PNG images is not saved correctly when used as a plugin (DLL version), so be sure to run the stand-alone version if you are compressing PNGs with alpha transparency.

Very good image compressor. I've tested similar commercial software and "RIOT" had the best compression rate. Simple and easy with a small memory footprint. Recommended!
