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
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."

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 is2 file to jpg converter
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.
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. How to Convert IS2 Files to JPG: A
Converting IS2 Files to JPG: A Complete Guide The IS2 file format is a highly specialized container primarily used by Fluke thermal imaging cameras. Because these files store more than just a picture—they include raw temperature data, metadata, and infrared sensor information—you cannot open them with standard photo viewers like Windows Photos or Preview.
To share these thermal images or include them in standard reports, you must convert them to a universal format like JPG. What Exactly is an IS2 File?
An IS2 file is a "Thermal Image Data File". Unlike a standard JPG, which only stores colors, an IS2 file acts like a RAW digital camera image. It captures:
Radiometric Data: Every pixel contains a temperature reading.
Visible Light Image: Many Fluke cameras take a standard photo at the same time for reference.
Metadata: Information about the camera settings, date, and location. Top Tools for Converting IS2 to JPG
Because the format is proprietary, standard online converters often fail. You typically need software specifically designed for thermography. 1. Fluke SmartView (Recommended)
This is the official software for Fluke camera users. It is designed to "view, optimize, and analyze" infrared images and is the most reliable way to export to JPG.
Best for: Professionals who need to maintain data integrity.
Key Feature: You can adjust the "Level and Span" (thermal contrast) before saving the final JPG.
Availability: Frequently included with Fluke cameras or available via the Fluke Support Page. 2. Fluke Connect (Mobile & Desktop)
A modern cloud-based platform that allows you to wirelessly download images from your camera to a smartphone or PC. The Ultimate Guide to IS2 to JPG Converters:
How it works: Sync your camera to the app, select the .is2 file, and use the Export function to save a version as a JPG. 3. IRT Cronista by GRAYESS
A professional-grade thermographic organizer and reporter that supports the IS2 format.
Best for: Users who manage thermal images from multiple different camera brands, as it handles various proprietary formats. 4. The "Zip" Workaround
In some versions, an IS2 file is actually a compressed archive.
Quick Tip: You can sometimes rename the file extension from .is2 to .zip. When you open the folder, you may find a VLImage or Thumbnail JPG already inside that you can extract directly. How to Convert: Step-by-Step (Using SmartView)
IS2 File Extension: What Is It & How To Open It? - Solvusoft
Most commonly, .is2 files are 3D scene files created by IronCAD. However, they are occasionally found as image files produced by specific thermal imaging cameras (like certain Hikvision or old Fluke models).
Here is a guide on how to convert an .is2 file to .jpg based on the most likely source.
If you have found a file with the .IS2 extension on your computer, you are likely dealing with a proprietary data file generated by Illumina sequencing instruments or specific infrared thermal imaging cameras (such as certain Fluke or legacy industrial cameras).
Because .IS2 is not a standard image format, you cannot simply rename it to .jpg or open it in common image editors like Paint or Photoshop. This guide explains what these files are and the specific software you need to convert them into viewable JPG images.
In the world of digital imaging, the average user is familiar with standards like JPEG, PNG, or TIFF. However, researchers, geologists, and forensic experts often deal with proprietary formats that contain far more data than a standard photo. One such format is the IS2 file.
If you have stumbled upon a file with the .is2 extension and are frustrated because your standard photo viewer or image editor won't open it, you are not alone. This article provides a comprehensive deep dive into what an IS2 file is, why you might need to convert it to the universally accepted JPG format, and the most reliable methods to perform this conversion.
This is the scenario most users encounter when looking for a simple image converter. IS2 files often originate from thermal cameras (often associated with Fluke thermal imagers) and contain the thermal matrix data, visual light camera data, and temperature measurements all wrapped into one file.
Why you need special software: A JPG is a flat image. An IS2 file is a "container" that holds thermal data, temperature scales, and visual overlays. To get a JPG, you must "flatten" this data using the manufacturer's software.
