RIOT - Radical Image Optimization Tool Comments

Not a serious solution

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, I found very good alternatives like XnConvert: lightly more complex interface but much more options and features !


Portable version is clean

Comment by RobertL87
about RIOT - Radical Image Optimization Tool and Caesium, GIMP, IrfanView Dec 2015

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!

[Edited by RobertL87, December 22]
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!


Contains trojan

Riot-setup.exe contains a trojan, use caution. See this VirusTotal analysis.


Beware: PUP!

Comment by wdburgdorf
about RIOT - Radical Image Optimization Tool May 2015

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


Note on plugin version

Comment by 10basetom
about RIOT - Radical Image Optimization Tool May 2013

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!
