In depth

A closer look at nomacs

nomacs is an intuitive image viewer that offers support for a wide range of file formats and editing capabilities.Thanks to its well-organized set of functions, you can easily configure the dedicated parameters. Photos can be uploaded into the working environment using “drag and drop” operations or the built-in browse function.Plus, it provides quick access to the files and folders stored in your computer, so you can easily select the image that you want to view and process.The tool lets you open photos with the following file formats: PNG, JPG, BMP, PPM, ARW, PSD, DNG, TGA, ICO, CRW, MPO, and others as well.What’s more, you can zoom in or out, go to the next or previous picture from the selected directory, sort items by filename, creation date, date when they were last modified, and ascending or descending order, and switch to a full screen mode for a better focus on your work.You can also view your photos displayed in a thumbnail list or slideshow, check the metadata (e.g. model, exposure time, rating, date), show or hide the built-in histogram, perform search operations, and change your wallpaper.Nomacs gives you the possibility to rotate the images to different angles, resize or crop the photos, view the GPS coordinates, use hotkeys (which can be reassigned), and print or save the edited photos to JPEG, PNG, TIF, BMP, PPM, or other file format.Last but not least, you can make file associations, rename items, copy the current image to the clipboard, adjust the levels of brightness, contrast, saturation, hue, gamma, and exposure, create mosaic images from multiple pictures stored in your computer, as well as export data to Tagged Image File Format (TIFF).All in all, nomacs offers a handy set of features for helping you view images and apply several editing options. Thanks to its intuitive layout, it is suitable for rookies and professionals alike. If you want to skip the installation steps, you can download the portable version of the program, which can be found here.
