Converting ARW to JP2

ARW is the proprietary format used by Sony cameras to create and store RAW image files — uncompressed images which can be later on adjusted using image editing software. RAW images are popular among photographers because they allow an advanced degree of customization during digital post-processing. However, ARW files, like most RAW images, tend to be very large in size, which makes them difficult to store and transfer.

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.

So, how to change ARW into JP2?

The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter.
