CPix

Quick, lightweight image viewer supporting multiple formats and batch operations.

Feature-Rich and Lightweight Image Viewer

CPix stands out as a fast and compact image viewer for Windows that goes well beyond basic image browsing functionality. Developed by FileFriend, the application is designed for efficient photo viewing while offering an impressive range of features, typically found in more robust software suites.

Wide Array of Supported Formats

One of the strongest aspects of CPix is its broad format compatibility. It handles common image types such as JPEG, PNG, GIF (including animations), BMP, TIFF, and APNG. It also recognizes less typical and specialized formats — including MPO (Multi-Picture Object), EMPO (Encrypted MPO), EJPG (Encrypted JPEG), PL (Photo List), and its proprietary DualPhoto format, which can store two JPEG images in a single encrypted file. This support ensures users can manage both standard photos and more complex datasets or secure images without switching tools.

Batch Processing and Conversion Capabilities

Photo management is simplified with CPix's batch processing options for both resizing and format conversion. Users can quickly convert multiple images or resize them to custom dimensions in a single operation, streamlining workflows that would otherwise be time-consuming. However, batch resizing is currently limited to JPEG, PNG, and BMP formats.

Image Encryption and Security

A unique feature is the option to encrypt certain image formats. This is particularly valuable for those concerned about image privacy, allowing secure sharing or storage of photos. The proprietary encrypted formats (like EMPO and EJPG) ensure that sensitive content is kept safe, accessible only with the appropriate CPix tools.

Customization and Playback Options

CPix offers several customization settings, such as adjusting photo orientation upon loading, selecting background colors, and tweaking the order in which images are viewed. For animated files, users can modify playback speed and enable or disable automatic playback. The frame-by-frame view is especially useful for detailed analysis of animations or photo bursts.

Interface and Usability

The user interface is minimalistic and intuitive, making navigation straightforward. Even with its wide feature set, CPix maintains a small installation footprint and runs quickly, never bogging down even with large folders or high-resolution images. The application is completely free, with no upsells or feature locks.

Limitations

While CPix brings advanced functionality to image viewing, certain operations are restricted based on file format — specifically, not all editing tools and conversions are available for every supported file type. Users dealing with formats outside JPEG, PNG, or BMP might encounter these limitations.
