RIOT Review

Fernando Ortega
Optimizes images such as JPG, GIF and PNG for compression and colors
A review of RIOT by Fernando Ortega

RIOT is an image optimizer which performs different modifications on an image such as the number of colors, the type of compression used and the format in which the program has been saved.

The application interface includes a before-and-after preview which is good for comparing the original with the optimized image. The interface of RIOT itself is clean and easy-to-understand while supporting the top three image formats: PNG, JPG and GIF.

When RIOT creates GIF and PNG images for the web, it will reduce the amount of color used in the image in order to reduce the size of the picture. The interface of RIOT also allows you to adjust quality settings and apply filters like greyscale. Additionally, it can remove IPTC information from the EXIF metadata.

Overall, RIOT is able to save a lot of space for uploading images to the web, sharing them via email or just to save disk space.

RIOT features and highlights:
  • Open many image types including rare/scientific types
  • Save and optimize jpeg, gif and png with a simple, clean user interface
  • Works in dual view: (original – optimized image) or single view (optimized image).
  • Automatic preview of resulting image
  • In-place compare function (alternativelly display the original image over the optimized image to notice small pixel changes)
  • Compress files to desired filesize threshold
  • Fast processing (all is done in memory);
  • See instant results including resulting filesize
  • Batch support (process multiple files at once)
  • Transparency handling options
  • Decide if you want to keep metadata (comments, iptc, adobe xmp, exif profiles, icc profiles).
  • Unsupported metadata is removed
  • Transfer metadata between image formats (destination format must support them)
  • Common tools: pan and zoom, rotate, flip
  • Basic image adjustments: brightness, contrast, gamma, invert
  • Visually reduce number of unique colors for png and gif images in order to reduce filesize
  • Resize image by using well known resample filters (ex: lanczos3, catmull rom, bicubic, and others)
  • Out-of-the-box support for external png optimizers (optipng, pngout, etc)
  • The compression and the results are comparable to those of commercial products, even higher.
  • Adaptive logarithmic tone mapping algorithm (drago) used for HDR images
