ARN is a rare image file format associated with the Astronomical Research Network, an American association formed in 1989. ARN files contain astronomical information and images, and can be created using software programs developed by the Network for PCs and Macs. The format is, however, incompatible with most regular image viewers, so we recommend converting it to a more accessible format.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple ARN files as once.
