File Format

The file format for an image is a way to encode and store visual data, defining how pixel information, metadata, and compression are handled. Examples include JPEG (lossy compression for photos), PNG (lossless with transparency), and GIF (limited colors but with animation).

Why do we test it?

Determining the file format is crucial for ad servers to ensure compatibility, optimize delivery speed, and maintain quality standards for diverse advertising platforms.
