File Extension

The file extension indicates the type of image format being used, such as .png or .jpg. Each format has its advantages depending on the use case.

Why do we test it?

Ensuring the correct file extension is important because different formats support different features. PNG, for example, supports transparency, while JPG is more suitable for smaller file sizes. Using the right format ensures compatibility with ad networks and optimizes the trade-off between quality and load speed.
