Convert RLA to APNG (Animated PNG)

The RLA file extension stands for Run-Length Encoded, Version A, a bitmap image format developed by Alias/Wavefront. It is primarily used for storing raster graphics with run-length encoding to compress image data efficiently. RLA files are compatible with various image viewing and editing software, such as XnView. This format was popularized in the early days of computer graphics for its ability to handle arbitrary image channels and support efficient storage of large images.

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.
