Converting IS2 files to JPG is a common challenge for professionals using thermal imaging cameras. Since IS2 is a proprietary format used by Fluke Ti-series cameras, most standard photo viewers cannot open them. This guide explains how to convert these files safely while preserving your thermal data. What is an IS2 File?
An IS2 file is a "radiometric" data container. Unlike a standard photo, it stores more than just pixels; it contains thousands of individual temperature data points. This allows thermographers to adjust settings like emissivity, level, and span after the photo has been taken.
While IS2 files are powerful for analysis, they are difficult to share. Converting them to JPG makes the thermal images viewable on any smartphone, computer, or web browser, making it the best format for quick reporting and client presentations. The Best Ways to Convert IS2 to JPG
Fluke SmartView Software (Official Method)The most reliable way to convert IS2 files is through Fluke’s own SmartView software. This desktop application is designed specifically for their camera line. Open your IS2 file in SmartView.
Perform any necessary thermal adjustments (scaling or color palettes). Go to "File" and select "Export." Choose JPG as the output format.
Fluke Thermal StudioFor users with newer camera models, Fluke Thermal Studio is the modern successor to SmartView. It offers batch conversion features, which are essential if you have hundreds of images from a single site inspection. You can select an entire folder of IS2 files and export them to JPG in one click.
Online File ConvertersIf you don't want to install software, several cloud-based conversion tools support IS2. However, be cautious:
Quality Loss: Online converters often strip away the metadata.
Privacy: Avoid uploading sensitive industrial or residential inspection data to third-party servers.
Data Integrity: You will lose the ability to change temperature scales once the file is a JPG. Why JPG is Better for Sharing
Universal Compatibility: JPGs work on every operating system without plugins.
Smaller File Size: IS2 files are bulky due to the embedded data; JPGs are highly compressed and easy to email. is2 file to jpg converter
Easy Integration: You can drop JPGs directly into Word documents, PowerPoints, or PDF reports. Important: Radiometric vs. Non-Radiometric JPGs
When converting, be aware that a standard JPG is "flat." You will see the thermal colors (like ironbow or rainbow palettes), but you will no longer be able to click on a pixel to see the exact temperature. If you need to perform further analysis, always keep your original IS2 files as a backup and only use the JPG versions for viewing and documentation. Final Verdict
For the best results, stick to Fluke SmartView or Thermal Studio. These tools ensure the color mapping remains accurate during the conversion process, giving you a professional-grade JPG that looks exactly like the image on your thermal camera's screen.
Converting an (a proprietary radiometric thermal imaging format used by cameras) to a standard
typically requires specific manufacturer software or specialized thermal analysis tools. Because IS2 files contain raw temperature data rather than just pixels, standard image converters usually cannot read them. Recommended Conversion Methods 1. Official Software: Fluke SmartView The most reliable way to convert these files is using Fluke SmartView desktop software. : Open your image in SmartView, go to the menu, and select . You can then choose as the output format.
: This preserves the thermal data and allows you to adjust the color palette or temperature scale before saving. 2. Specialized Thermal Analysis Tools
If you do not have the Fluke software, other thermographic analysis programs like IRT Cronista by GRAYESS also support the IS2 format.
: 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)
For users comfortable with technical tools, there are open-source utilities like the fluke-ti-tool available on
: This tool specifically converts Fluke IS2 thermal images to
files, which can then be easily saved as JPGs using any standard photo editor or online converter like Adobe Express Why Online Converters Often Fail Converting IS2 files to JPG is a common
Most general online converters (like CloudConvert or Zamzar) support standard camera RAW files (like Sony's SR2) but do not natively support the proprietary
radiometric format. If you attempt to use a generic tool, the file will likely be rejected as an "unsupported format." CloudConvert Key Features of IS2 Files : Contains raw infrared data, not just a visual image. : Classified as a data/thermal imaging file. Primary Application : Fluke SmartView. download link for the official Fluke SmartView software? JPEG Converter - CloudConvert
Converting an .is2 file to a .jpg is a common task for users working with Testo thermal imaging cameras. Since .is2 is a proprietary format containing raw radiometric data, standard image viewers cannot open them directly. 1. The Official Method: Testo IRSoft
The most reliable way to convert these files is by using the manufacturer's official software. Software: Testo IRSoft (Free download).
Process: Open your .is2 file in IRSoft, adjust your temperature scales or palettes if needed, and use the "Export" function to save the image as a .jpg.
Pro: Retains the highest image quality and allows you to toggle thermal data overlays. 2. Batch Conversion for Large Projects
If you have dozens of infrared scans, manual exporting is tedious.
IRSoft Batch Process: Within the Testo software, look for the "Batch processing" or "Report wizard" feature. This allows you to select a folder of .is2 files and convert them all to .jpg or .pdf reports simultaneously. 3. Third-Party Alternatives
While niche, some advanced image processing tools can handle .is2 files:
FileZigZag / Online Converters: Some web-based tools claim to support .is2, but these are often hit-or-miss with proprietary thermal formats and may strip away the radiometric metadata.
GraphicConverter (macOS): Known for supporting over 200 legacy and proprietary formats, this is a solid choice for Mac users who don't want to run Windows-based IRSoft. Why use .jpg instead of .is2? You might ask: Why not just keep the original IS2
Universal Compatibility: View your thermal captures on any phone, tablet, or PC without special software.
Reporting: Easily embed images into Word documents, emails, or PowerPoint presentations for clients.
File Size: .jpg files are compressed and easier to share than the data-heavy .is2 format.
Note: Once converted to .jpg, you lose the "radiometric" capability—meaning you can no longer change the emissivity settings or pick specific temperature points on the image like you can in the .is2 original.
You might ask: Why not just keep the original IS2? The answer lies in accessibility and workflow:
For laboratories running high-throughput sorting machines (e.g., recycling plants using Specim cameras), manually converting each file is impossible. The solution is Batch Processing.
Most reputable IS2 to JPG solutions require SDK integration. Specim provides an SDK (Software Development Kit) that allows you to write automated scripts that:
If you are processing thousands of files per day, do not use a GUI converter; invest in a Python developer to script the process using the Specim SDK.
For this guide, let's assume we don't have a direct converter and we'll use an online tool. There are several available, such as Convertio, Online-Convert, or Zamzar.
If you have software (like Adobe Photoshop, or a specialized GIS or CAD tool that supports IS2), you can open the IS2 file, then save or export it as a JPG.
