QTK to AVIF Conversion: FAQ

What are QTK files?

QTK is the proprietary format used by Apple QuickTake cameras for shooting in RAW mode. QuickTake was an innovative digital camera released by Apple in 1994 — it represented one of the first models which could store digital photos and connect to an Apple computer to download them. Nowadays, however, QuickTake cameras are not directly compatible with the Mac OS X platform due to the absence of an old Apple Serial protocol. QTK images can be downloaded using special applications or programs, and converted to more accessible formats.

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency.
