nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images.
nomacs features semi-transparent widgets that display additional information such as thumbnails, metadata or histogram. It is able to browse images in zip or MS Office files which can be extracted to a directory. Metadata stored with the image can be displayed and you can add notes to images. A thumbnail preview of the current folder is included as well as a file explorer panel which allows switching between folders. Within a directory you can apply a file filter, so that only images are displayed whose filenames have a certain string or match a regular expression. Activating the cache allows for instantly switching between images.
nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, exposure. It has a pseudo color function which allows creating false color images. A unique feature of nomacs is the synchronization of multiple instances. With this feature you can easily compare images by zooming and/or panning at the exactly same position or even by overlaying them with different opacity.
nomacs is licensed under the GNU General Public License v3 and available for Windows, Linux, FreeBSD, Mac, and OS/2. It is free for private and commercial use. If you want to report any bugs or request new features please use our tracker.

Cuckoo Sandbox is free software that automated the task of analyzing any malicious file under Windows, macOS, Linux, and Android.
JPEG files can be transformed into the JPEG XL form without quality loss, while reducing their size by 22%. JPEG XL preserves all the data in a more efficient container, where the integrity of an original photograph is maintained byte-by-byte — without damage to our digital cultural heritage.
On this page you can be one of the first to try out the new compression technology on your photographs. The conversion process runs locally in your browser using WebAssembly technology, no images are uploaded to servers. This demo only works with .jpg files, there is no .png nor .gif support at the moment.
Lossless recompression improves JPEG XL’s compatibility with existing clients such as older generation phones and browsers not yet having dedicated JPEG XL support. The lossless recompressing feature simplifies the ecosystem migration to JPEG XL: servers can store a single JPEG XL file to serve both JPEG and JPEG XL clients, and multiple efficiency and transfer speed improvements will be available in an ecosystem having a rich mixture of old and new clients. The format has several flexibility considerations for interoperability and migration of JPEG to JPEG XL, and incremental steps of quality improvement can be taken while remaining compatible with both the old and new formats.
