I am a webdeveloper myself and I started this program because I know the importance of such a tool.
Creating a standalone tool would have never been a success. It would be very hard for people to find about it and use it. I cannot advertise it. I don’t have a team for that.
So my first ideea was to integrate it in the most popular image viewer worldwide – IrfanView, that is also free and accepts plugins.
I am a IrfanView user for many years. This is my favourite program.
I thought it would be great to add something that is missing for years into this great program – a save for web feature.

So I talked with Irfan and we set the details. I wanted to create it in C#, but he didn’t want the big .net framework as dependency even if on Vista and future windows systems it is installed by default.
I started a similar project in 2003 in C++ and left it in alpha state. So, I used my old sources and found a good library called FreeImage. I made some contributions to FreeImage (of course all of them are available for free for the community).
And here is the final result – RIOT.
Irfan didn’t want to deploy 2 DLLs. Just one, he said, and smaller. I managed to link FreeImage, pnglib, libjpeg and zlib with Borland C++Builder, even if they are not compatible with this compiler.
This resulted in a lite DLL with stripped functionality.
I decided to maintain all advanced features by creating another version of the plugin called Extended version (also free) – formerly named FULL.
For people that don’t have/use IrfanView I created also an EXE (with extended features), and that version became now the RIOT application.

Meanwhile the RIOT plugin was integrated in other programs who benefit of the save for web features like: XNView, GIMP or Paint.NET

    Just a big thanks for this product. It saves tons of time and gives the best results without going into complexity of other bloated tools like Photoshop and stuff.

  4. Mike says:

    Any chance of you adding a command line feature to RIOT? Love the plugin!

  5. Ivan says:


    Really usefull tool… But i need something like RIOT but as command promt only for windows…. Cause ImageMagick is not good at all for that.. Maybe you can advice? )))

  6. Ezeem says:

    I wonder why you did not implement
    Batch >Sub Directory functions…
    One should be able to select the ‘parent directory’ and ‘sub-folders’ and the program could easily
    clean up images in all sub-directory and over-write them respectively and clean them instead of a person to choose a directory one by one as an ‘output folder’ option.

    Anyway its a good product you have made…. please add me thoughts to the ‘wishlist’

  7. Chen says:

    Lovely tool and nice of you to give it free! Tested it.. Batch functions need 2 things:
    1. Ability to choose/ spider folder and sub-folders to optimize and clean metas
    2. Right click mouse to choose a folder/sub-folder so program is added to run
    Will be in touch with you… have some JV ideas too!

    For an honest installer which didn’t install third party software when I declined but most of all thanks for a very slick optimiser.

    @Peter: HTMLCleaner is not actively developed but I will fix bugs if reported. I made a change in the blog and the link does not work, but I will fix it

  21. Peter2 says:

    Hi Lucian

    the above link to “CRIOSWEB’s HTMLCleaner” is dead. Is the project still alive?


  22. TRos says:

    Hi, Lucian!

    Your app is great! It helped us to optimize the graphics on our big soft portal.

    We want to add your program to our catalogue, but as far as it has English interface, we want to offer you to translate it into Russian (and maybe Ukrainian) for our users.

    If you’re interesting in localization, please, write us as soon, as you’ll be able.

    Thank you for your application!

  23. Johnny Lai says:

    Hi Lucian,

    This is really a great program. Your program has take over from the previous program i used to optimize pictures, WebGraphiOptimizer.

    If you would like to have it translated into Danish and maybe into Chinese i could help you out if you want me to.
