RIOT: Save optimized web images from Irfanview

RIOT image optimizerI’m a big fan of Irfanview. It’s one of the best examples of how I think all software should be: small, light and with just the right features. I use it every day, and can’t recommend it enough. But Irfanview isn’t perfect. It applies the default worst icon I’ve ever seen to your images, but more importantly it’s not very good at optimizing images for the web. JPEGs saved from Irfanview were consistently worse in both quality and file size compared to the same saved through Photoshop’s ‘save for web’ feature. That’s where RIOT comes in.

The ‘Radical Image Optimization Tool’ can either be used as a standalone program or as a plugin to Irfanview. It takes your image and lets you set things like image format (jpg/gif/png), color depth and compression levels. It also allows you to scale, rotate and flip the image before saving and optimize to a specific file size. The only thing I really miss compared to ‘save for web’ is dithering with indexed color images, but I have to admit I rarely use that anyway. On the other hand, RIOT has a few settings that Photoshop doesn’t have, such as control over chroma subsampling.

With RIOT, saving images for use in blog posts has gotten a lot easier and quicker for me compared to going through Photoshop. It works really well and is free to boot.

  1. Use this every day and can’t get enough of it (RIOT and Irfanview together), such an easy workflow using these two together.

  2. Irfanview is really a great application, easy to use and can be learned by yourself. I use it for quitesome time and never faced any problem.
    Best part i liked about it is save for web applications, in which one can optimize image for web use. Also resizing image in terms of dimension is also a great help.

  3. Thanks for publicising this, I’ve used irfanview for years but hadn’t realised they’d added this in the latest versions.
