Portable RIOT Description
open many image types including rare/scientific types
(up to 128 bpp, integer and floating point).
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);
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
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.
