No GIF images used

This check reports when the file format of any placed images is GIF.

GIF, pronounced with a hard G (Graphics Interchange Format) images are a mostly obsolete file format.

Although they can contain transparency they can’t handle amounts of transparency. Each pixel is either a solid colour or transparent.

GIF cannot display more than 256 colors and cannot be colour managed. For this reason, it is less effective for displaying photographs online (use JPEG instead) and is not recommended for commercial printing. If the image has flat colour or includes type, use the PNG format instead.

Tip: It is possible to switch on a column to show file types (a.k.a. Formats) in the Links Panel. (Window > Links) using the Panel Options.
