Sometimes your pictures don’t have best optimization settings. In order to make corrections, proper tools are required, such as the Portable RIOT.
Radical Image Optimization Tool is a program that can help you process images with the best compression ratio and quality. This makes it easier to optimize the photos for websites and emails.
The software has a simple interface, holding the before and after images at the center of the frame. You can automatically preview the resulting image, as it updates immediately after each alteration. In order to better see the changes, you can zoom in and zoom out of the picture, display the images at their full size or make the picture fit the frame.
Also, Portable RAID comes with a function called “in-place compare” that enables you to alternatively display the original image over the optimized image to notice all the changes.
The app can save JPEG, GIF and PNG files with a few simple steps. Thus, you can modify the quality and chroma subsampling, as well as the encoding for JPG, choose a color palette and a number of colors for GIFs and PNGs.
Further adjustments can be made in regards of the picture’s brightness, contrast and gamma values. You can also invert the colors.
Furthermore, the app also comes with a function that enables you to keep or remove metadata. The program lets you know which type of metadata is included with the photo (IPTC, Adobe XMP, EXIF profile, ICC profile or comments) and gives you the opportunity to remove it.
Portable RIOT also supports batch conversion. Files can be loaded individually or as entire directories. Additional tasks that can be applied include flipping, rotating, resizing and compressing all the selected pictures.
All in all, Portable RIOT is a nice app that can be of use when you need a fast working tool. One of the major advantages of this program is its flexibility, as it can be run from any portable device, without having to install it on your computer.
What's New in This Release:
· added automatic optimization mode
· added loading support for "half float" format to TIFF
· added drag folder to load files in batch mode
· added progress monitoring for jpeg load/save and resize
· superior internal PNG compression. Added 4 compression levels (zlib-9 with heuristics and filters for low setting and zopfli deflate used for the higher settings)
· color quantization to 2 colors now outputs 1 bit images instead of 4 bit (smaller filesize)
· changed transparency settings (added simplify checkbox)
· faster color quantization of images with 16 colors or less (output bit depth controlled by the quantizer itself)
· greatly improved resize/resampling speed
· upgraded to LibTiff 4.0.3
· upgraded to libPNG 1.5.13
· upgraded to OpenJPEG 1.5.1
· allowed loading of PNG with benign errors (such as images with too many IDATs)
· batch settings: keep date date & report size changes options are now preserved
· fixed crashing when loading some JPEG files with invalid EXIF tag length
· fixed PNG plugin with saving of ...
