File format
Only JPEG (JPG) files are permitted.
PNG files are not allowed in order to optimize the file size and loading speed of the website.
Resolution and Compression
Maximum resolution: 72 DPI (dots per inch) for online use.
Compression level: Optimize the file to a quality of 60-80% (in an editing program such as Photoshop) to reduce the file size without significant loss of quality.

For large banners, such as a leaderboard (728 x 90 px), it is essential to stay below 150 KB.
Smaller banners, such as mobile advertisements (320 x 50 px), should ideally be around 50-100 KB.

Ensure that images do not contain unnecessary metadata, which can unnecessarily increase the file size.
