Importing .sid file and converting to .TIFF

Hello,

For a current project, I have received a .sid file of an aerial map. The study area is very large, and the image size is 4.9 megabytes.
I would like to import this .sid file into ArcMap, and convert into a high resolution .TIFF (approximately 10000 x 10000)

Is there a way to do this in ArcMap? And if it cannot be done in ArcMap, does anybody have any experience with this type of file conversion?

Thanks,
Katie
