Author: Cedric Louvrier

Pinga is an application for compressing image files in JPG and PNG formats. The software offers both lossy and lossless compression settings. The interface is designed for straightforward image processing operations. The program modifies the original files directly, so it is recommended to work with copies of the images. Pinga functions as a graphical interface for the pingo command-line utility, providing visual access to its compression capabilities.

Lossless compression. Reduces image file size without affecting visual quality. This technique removes unnecessary metadata and optimizes the file's internal data structure. The algorithms reorganize image information to achieve a smaller size while retaining all original data.
Lossy compression. Reduces file size by selectively removing less perceptible visual information. The user controls the compression level through quality adjustments. Higher compression ratios result in smaller file sizes but may introduce visible artifacts.
Auto-lossy compression. Automatic application of lossy compression optimized based on image characteristics. The algorithm analyzes the visual content and determines the optimal compression parameters. This method seeks a balance between size reduction and quality preservation.
Resizing for web. Adjusts image dimensions to sizes appropriate for internet publication. The function maintains the original aspect ratio, avoiding distortions. Includes options to define specific dimensions in pixels or percentages relative to the original.
Metadata removal. Removal of additional information stored in image files. Metadata can include EXIF data, embedded color profiles, and creation information. This reduction contributes significantly to decreasing the final file size.
Grayscale conversion. Transformation of color images to monochromatic representation. The process applies conversion algorithms that preserve the original image luminosity. This conversion can reduce file size by eliminating color information.
sRGB color space conversion. Standardization of the color profile according to the sRGB space, widely compatible with web browsers and devices. The conversion ensures consistent display across different platforms. This normalization can optimize size when large ICC profiles are removed.
Image rotation. Adjustment of image orientation based on EXIF metadata or manually. Corrects the display for images captured with incorrect orientation on mobile devices. Rotation is applied before compression processes.
Dithering application. A blending technique that reduces color banding in images with limited palettes. Dithering distributes quantization errors to simulate intermediate colors. This option may slightly increase file size but improves visual quality in certain cases.
Batch processing. Application of compression operations to multiple files simultaneously. Allows configuring uniform settings for groups of images. Batch processing saves time in projects requiring consistent treatment of multiple files.
Drag-and-drop interface. File loading method via drag-and-drop from the file explorer. Users select images and drag them directly onto the application's workspace. This implementation streamlines the workflow for quick operations.
Progress indicators. Display of progress during compression operations. Shows the percentage completed for each processed file. The indicators provide feedback on the remaining processing time.

Pinga was developed as a graphical interface for the pingo compression tool. The program was created to make pingo's capabilities accessible to users who prefer visual interfaces. The development was primarily done in programming languages such as C++ and possibly WinAPI components for the interface. The underlying pingo tool was created by Christian Kaiser, with contributions from other developers on the project.
