Hi guys,
While going to convert large files( around 25mb of TIFF extension), the process hung. I could not understand why the file was not converted but when it is smaller then is converted with ease.

What version of IM, on what platform?
The bytes/file isn't usually relevant. How many pixels? Please give the exact command you used.
If you don't have enough memory for all the pixels, it would use disk, but should eventually finish.

The conversion works fine for me, IM v6.8.9-0 on Windows 8.1, with 12 GB memory. It takes 36 seconds.
Your image has 581 m pixels. At 8 bytes/pixel, this needs 4.6 GB memory. If you have less than about 6-8 GB memory, I expect it is using disk.
