GBX to IFF Conversion: FAQ

What are GBX files?

GBX is an image file format included in the Gerber group of extensions, which represents a de facto standard in the printed circuit boards (PCBs) industry. Over 20 different extensions are part of this group — including GBL, GTS and GBS — and each describes a different detail from a PCB, which is meant to be transmitted to the photoplotter that manufactures the board. Such details can consist of silkscreen or copper layer features, drilling data etc.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
