SIM to WEBP 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 WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
