When a folder holds many pictures or a camera RAW file needs a quick look, Nomacs brings image browsing and basic adjustments into one viewer. It opens common image types, including RAW and PSD, and provides tools for comparing views and inspecting image details.
Folder browsing and image details
A file-explorer panel provides a route between folders, while a thumbnail strip shows other images in the current directory. Filename filters can narrow the visible files by a text string or a regular expression. Enabling the cache can speed up switching between images.
Nomacs also provides semi-transparent information panels for details such as thumbnails, metadata, and a histogram. Image metadata can be viewed, and notes can be added to pictures.
Synchronized image viewers
Open images in multiple viewers to compare them, then synchronize actions such as zooming and panning. The views stay aligned as you inspect corresponding areas, which suits checking edits or comparing similar pictures.
Image adjustments and formats
Alongside viewing, Nomacs includes controls for cropping, resizing, rotating, and changing image color. Brightness, contrast, saturation, hue, gamma, and exposure adjustments are also available; a pseudocolor function can apply false colors.
Besides the usual formats it reads camera RAW files and Photoshop PSD documents. It can also browse pictures inside ZIP archives or Microsoft Office files, extracting them to a directory for access.
