Its format list identifies RAW support through LibRaw when the build includes ENABLE_RAW, and PSD documents as read-only through KImageFormats. Check your distribution’s package details and test your own files before relying on either format.
What nomacs can do with RAW and PSD files
nomacs is a multi-platform image viewer, not a guarantee that every camera RAW variant or Photoshop document will open in every Linux package. The nomacs project homepage describes support for common image formats, including RAW and PSD. Its more detailed format support page explains the conditions behind those categories.

RAW files
The format list associates RAW support with LibRaw and the ENABLE_RAW build option. It names examples including CR2, CRW, NEF, ARW, MRW, and RW2. That list does not confirm that a particular Linux package includes the option or that every camera-specific file will work. Check the package or build information for your installation, then try an actual file from your camera.
PSD files
Photoshop documents are listed under KImageFormats as read-only. This makes nomacs useful for viewing a supported PSD, but the listing does not establish that every PSD feature or document will render as it does in Photoshop, nor does it describe PSD editing or export support.

#1 Best Overall
- Stereo Wide-View Viewer for Prints and Monitors
- Designed to take up where most viewers leave off - viewing side-by-side (parallel) stereo pairs, larger than 3-1/2" x 5"
- Ideal for viewing images on TVs, computers, pads, and even a side of a barn, easily up to 14 feet away, or even more.
Tools for browsing and comparing images
Beyond opening individual images, nomacs includes a file explorer, thumbnails, metadata and histogram widgets, filename and regular-expression filtering, and cache-assisted image switching. The project also says it can display images contained in ZIP or Office files. Availability of a particular format still depends on its provider and the build.
For comparison, multiple nomacs instances can synchronize zoom and panning, or use opacity overlays to compare views. The viewer also offers adjustments for brightness, contrast, saturation, hue, gamma, and exposure, plus pseudo-color display. These are viewing and adjustment tools; they do not change the read-only status listed for PSD documents.
Install nomacs on Linux
The project’s installation page lists distribution repositories for AUR, Fedora, openSUSE, Debian, and Ubuntu, as well as Flatpak and AppImage. Package availability and versions vary by distribution and can change; the homepage’s displayed version is not confirmation of the version in a specific repository.
Rank #2

- Open the nomacs installation page and choose the route for your distribution, or select Flatpak or AppImage if you prefer a distro-agnostic option.
- Check the package source for its current version and any stated optional format support, especially LibRaw/RAW and KImageFormats/PSD.
- Install nomacs using the instructions for that source, then open representative RAW and PSD files to confirm they display correctly in your setup.
If a file does not appear or open
Format support can depend on both the file-format provider and how nomacs was built. A missing extension in an open-file filter is not, by itself, proof that the format cannot be displayed. A 2014 nomacs article describes trying File > Add Image Format to check support when a format is missing from the filter; treat this as historical troubleshooting guidance, not confirmation that the option or a particular camera file works in every current build. See the project’s article on adding image formats.
- For RAW, check whether your package includes the RAW-enabled build and LibRaw support; then test the specific camera file.
- For PSD, remember that the project lists Photoshop documents as read-only under KImageFormats.
- If support is unclear, compare the package’s format-provider details with the project’s format list or try another installation route, such as the project-listed Flatpak or AppImage.
Is nomacs a good fit?
nomacs is worth considering if you want a Linux image viewer with browsing, metadata, basic adjustments, and synchronized comparison, and your package can open the files you use. Before choosing it for a RAW or PSD workflow, verify the exact camera formats and documents you need, whether support is built in or plugin-dependent, and whether read-only viewing is sufficient. The project’s FAQ explains that comparing the same image after different processing stages was the original motivation for nomacs.
