However, while IS2 is excellent for research and analysis, it is notoriously difficult to share. You cannot attach an .is2 file to an email for a client, upload it to a standard CMS, or view it on a smartphone. This is why the demand for a has exploded in 2025.

Because the format is proprietary, traditional "universal" online converters often fail to read the radiometric data. You typically need specialized software provided by the manufacturer or professional analysis suites. 1. Fluke SmartView and Fluke Connect (Recommended)

: Professional software specifically designed to organize, analyze, and report on infrared images, with full support for the IS2 extension. 2. The "Zip" Hack (Quick Preview)

Figure 1 (not reproduced here) shows side-by-side comparisons: the proposed converter produces visually identical results to the manufacturer’s tool, with minor JPEG compression artifacts at quality 85.

A standard of the thermal and visual images is often stored inside as a preview. 3. Third-Party & Online Tools

: This is the primary software for managing Fluke thermal images. Users can open .is2 files to view and analyze temperature data, then use the Export function to save the image as a standard .jpg , .tiff , or .bmp .

This is the critical step that defines a new converter.

Converting IS2 files (InfraRed Snapshots) to JPEG is essential for viewing thermal data on standard devices. Since IS2 is a proprietary format used by Fluke thermal imagers, standard image viewers cannot open them without conversion. Overview of IS2 Files : Proprietary container for radiometric data. Content : Stores raw temperature values and visual metadata. Usage : Used primarily by Fluke Ti-series cameras.
