SIM to JP2 Conversion: FAQ

What are SIM files?

The SIM extension is associated with a rare and obsolete bitmap image format called Aurora. This might be linked to some old models of a 3D animation tool pack under the same name. SIM files are considered uncommon and they are difficult to open using regular image viewers.

What are JP2 files?

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.
