Radical Image Optimization Tool
RIOT is a radical image optimization tool and is free software for your Windows 64-bit PC. There is also a portable installer for both Windows 32-bit and 64-bit. The app offers plugins to use with XnView, IrfanView, GIMP, and more.
Image optimization is vital to lessen load times on sites. RIOT helps you by reducing the size of images without loss of quality. You can export your images as web-optimized jpeg, gif, or png. Compression is automatic, and you control the quality of the output files, regardless of the format. Alternatively, there’s also PhotoBulk, which can rename images in bulk, in addition to sharing some of RIOT’s features.
The software has a straightforward user interface with all options in plain sight. It gives you the size of the original and the processed image. The dual-pane lets you compare the original with the optimized image as you use the toolbar at the bottom to adjust settings to get the desired result. You see changes and updated file size immediately.
RIOT features
You can use the app to optimize bitmap, PSD, popular HDR, and specific RAW images. You can also drag and drop one or many photos to optimize in batches. You make JPEG adjustments by selecting a quality and chroma subsampling level.
Chroma subsampling lets you store colour information at a lower quality level. It reduces the image size, but changes are not noticeable to the human eye. But if you zoom in, you can see the difference. Feel free to choose between none, low, medium, or high. The higher the level, the less colour information the image will keep. With GIF and PNG, the software uses colour reduction to lower bit depth and decrease colours.
RIOT can also decrease the image size by removing metadata such as EXIF, IPTC, XMP, and ICC data.
Professional and novice users
RIOT offers simple functionality for novice users to flip, rotate, resize, or compress image files.
