A free program designed to efficiently optimize images for the Web

editor's review






RIOT is an application that enables you to reduce the size of your images for your websites.

Since this is an ad-supported software, you should be careful when installing it. RIOT offers to download a third-party component that it is not necessary for the program to fully function.

The interface of the tool is clean and simple. You can import images by using the file browser or the "drag and drop" method (batch processing is also supported).

You have several options at your disposal, according to the file format - JPEG, GIF or PNG.

So, you can configure JPEG options (e.g. adjust quality, select the chrome subsampling, apply a grayscale filter), metadata settings (e.g. remove IPTC info and the EXIF profile) and make image adjustments (e.g. brightness, contrast, gamma).

When it comes to the GIF and PNG extensions, you can select a color reduction method, specify the value to reduce colors to, as well as select the color quantization algorithm.

In addition, you can zoom in and out of the image, switch to batch mode, rotate, flip or resample the image, switch to full screen mode, disable dual view, use external optimizers, and more.

The app requires a low-to-moderate amount of system resources and includes a well-drawn help file with hints. We haven't come across any issues during our tests.

The fact of the matter is that RIOT is an excellent tool for optimizing image files and we highly recommend it to all users.
