If you are out in the field, using a Mac (as Fluke desktop software is primarily built for Windows), or simply do not want to install heavy software for a few files, online file conversion platforms can help.
The entire process typically takes just a few seconds per image.
If you only need to see the image and do not require the raw temperature data:
: Import the IS2 file and use the "Save As" or "Export" function to convert it to a standard raster format like JPG or PNG. 3. Developer/Technical Tools (PNG Conversion)

The .is2 file extension is most widely recognized as the proprietary raw image format for (such as the Ti90, Ti95, and Ti100 series) and the IRT Cronista software developed by GRAYESS Inc..
Imagine a standard digital photo—it only captures the colors and light your eyes can see. An IS2 file is much more powerful. It consolidates several different layers of data into one file, including:

If you need to perform further temperature analysis (e.g., changing the color palette or adjusting emissivity), you should use Fluke SmartView rather than a generic online image converter. If you'd like, I can:
