CompressO

CompressO is a free, cross-platform video compression application that uses FFmpeg. It is available for Linux, Windows, and macOS. The program is designed to reduce the size of video files while maintaining specific quality parameters.

• Video Compression. The compression process utilizes FFmpeg codecs to reduce the size of video files. Users can select different quality levels that affect the relationship between file size and the resulting visual quality.
• Quality Selection. A slider allows choosing between three predefined compression levels: low, medium, and high. Each level automatically adjusts the encoding parameters to achieve different results in the final file size.
• Resolution Change. This function modifies the video dimensions by altering the number of pixels in width and height. This allows adapting the content to different display requirements or storage limitations.
• FPS Adjustment. Controls the frames per second rate of the output video. Modifying this parameter affects the smoothness of playback and can influence the final size of the compressed file.
• Geometric Transformations. Includes operations for cropping, rotating, and flipping the video. These transformations are applied during the compression process to modify the visual composition of the content.
• Mute Audio. Allows the complete removal of the audio track during compression. This option generates silent video files for cases where only the visual component is necessary.
• Drag and Drop. Files can be loaded into the application by dragging them from the file explorer and dropping them onto the program's interface. This method provides an alternative way to select files.
• Compression Cancellation. During the compression process, users can interrupt the ongoing operation. This function immediately stops the processing and frees up system resources.
• Window Persistence. The application remembers the window's position and dimensions between sessions. When restarting the program, the interface appears in the same location and with the same size as the last time it was used.
• Refreshed Interface. The user interface design has been updated to incorporate additional controls and improve the organization of elements. The video configuration settings are presented in a structured way.
• Adjusted Minimum Height. The minimum window height is set to 800 pixels, a reduction from the previous 992 pixels. This change allows for correct display on screens with more limited vertical dimensions.
• Scaling Compatibility. Accessibility fixes for scaled resolutions have been implemented. These improvements ensure the interface displays correctly on screen configurations with custom scaling.

Development of CompressO began in 2025 and is still active. The application is written in the Rust programming language. The development is carried out by codeforreal1 and contributors through the GitHub platform.
