Description of RIOT 0.4.6

Optimize the image size for your web site

The Radical Image Optimization Tool (RIOT for short) was developed to be a free image optimizer that will let you to visually adjust compression parameters while keeping minimum filesize.It uses with a side by side (dual view) or single view interface to compare the original with the optimized image in real time and instantly see the resulting file size.It is lightweight, fast and simple to use, yet powerful for advanced users.

You will be able to control compression, number of colors, metadata settings and much more, and select image format (JPG, GIF or PNG) for your output file. Input image types: - common bitmap images as well as Adobe Photoshop PSD files- popular HDR formats and RAW camera images- rare / scientific types (up to 128 bpp, integer and floating point)

Key features

• 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).
• 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).
• 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 (two quantization methods are available: Xiaolin Wu and NeuQuant neural net)
• 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.

Editor's review for RIOT

RIOT, abbreviation for Radical Image Optimization Tool, is a freeware software program that allows you to optimize images. This software enables visual compression by adjusting the image parameters while simultaneously maintaining minimum size of the file.

This Radical Image Optimization Tool though very fast and lightweight is very powerful particularly in the hands of advanced professionals and experts. It is extremely user friendly and novices can also use it with full aplomb. It provides a dual side by side view to allow a comparison of the optimized image with the original so that an instant adjustment can be made as well as to make note of the size of the resultant file. The RIOT program also offers a single interface if you prefer for viewing the image being optimized. This software allows control of the compression as well as the colors and settings of metadata and many more optimization functions. The RIOT software can function with various file formats like PNG, JPEG or GIF. It can also be integrated with popular programs as a plug-in for XnView, GIMP and IrfanView.

The RIOT program can help open and optimize various types of images including scientific and rare image files without altering the originality. It is used to optimize and save files with GIF, PNG and JPEG extensions with a clean and simple user interface. It offers an automatic preview of the optimized image and it even allows super-imposing the original image on the optimized one to check for even the minutest changes in pixels. A distinct advantage of this RIOT program is that it is possible to compress the relevant images to the required file-size. The resultant size of the file as well as the optimized image can be viewed and compared as the program does processing in a fast manner and also in memory. The RIOT program has the ability to process and optimize the images in batches.

The software provides ultimate transparency in the handling options and offers choice for retention of metadata including ICC profiles and comments, EXIF profiles, Adobe XMP, and IPTC with the removal of unsupported metadata. Also this metadata can be transferred between image formats as long as the destination file format offers support for such action. The software supports normal regular options for flipping or rotating images or for panning and zooming into or out of the images. Also the basic adjustments are possible regarding inverting the image or modification and altering the gamma, brightness and contrast of the images. The availability of NeuQuant neural net and Xiaolin Wu, the two methods of quantization helps reduce virtually the number of unique colors for both GIF and PNG images so as to reduce the size of these files.

The RIOT program allows for resizing images with help from popular resample filters namely Bicubic, Lanczos3, Catmull Rom as well as others. RIOT offers unique and excellent support for PNG optimizers like pngout, optipng and others. The quality of the optimization of images resulting with RIOT is equal to those offered by commercial products and may be even more.

Read the RIOT Act and optimize all images to your satisfaction!
