nomacs is a free image viewer for windows, linux, and mac systems, which is licensed under the GNU General Public License v3. nomacs is small, fast and able to handle the most common image formats including RAW images. Additionally it is possible to synchronize multiple viewers. A synchronization of viewers running on the same computer or via LAN is possible. It allows to compare images and spot the differences (e.g. schemes of architects to show the progress).

Why webPMarch 1, 2013 : 16:27
according to a feature request from dadatamada we took a closer look to the webP format. the screenshot shows a nightly build of nomacs with webP load/save functionality. if an image needs to be compressed, webP shows a far better image quality while decreasing the file size. note that the jpg compressed image (right) has 16.6 KB while the webP image only needs 6.8 KB. another advantage is the fact that webP features a full (8bit) alpha channel and supports lossless compression…
