BIG to PSD Conversion: FAQ

What are BIG files?

The BIG image file extension is associated with Michelin maps. These maps have a long history in France, with the first printed version launched in 1905. They are mainly addressed to automobile drivers and in recent decades, the Michelin maps have become available in digital format too.

What are PSD files?

PSD is the default format for handling images using Adobe Photoshop and it represents a layered image file. PSDs allow later editing of available layers, including transparency, masks, alpha channels and texts, among others. After applying all desired editing, PSD files can be saved in Photoshop under more easily recognizable formats, such as JPEG or PNG, which are also smaller in size but flatten the image and hence do not allow later editing of layers.
