Extract text from Radiometric thermal images (IS2)
To convert IS2 Thermal images to another format, you need Fluke SmartView or other Raster Image software.
To convert other file formats to the "Radiometric Thermal Image" file type, you need software like Fluke SmartView or a similar tool.
The .IS2 file is a radiometric thermal image format generated by Fluke Corporation and FLIR thermal imaging cameras. It stores both a standard visible-light photograph and a layer of infrared radiometric data, meaning it records precise temperature values for every individual pixel in the image. Engineers, electricians, and home inspectors rely on these files for thermography analysis and energy auditing.
Despite its industrial utility, the .IS2 format is highly restrictive and proprietary. It cannot be natively opened by web browsers, macOS Preview, or Windows Photos. Sharing these files with clients or colleagues typically requires them to install heavy, specialized software like Fluke SmartView or FLIR Tools. Furthermore, because they pack visual data, sensor data, and metadata together - often using an internal ZIP structure - the files are unnecessarily large and cumbersome to share via email.
To make thermography data accessible to normal users, you must convert the file. For web sharing or embedding in a PDF report, convert .IS2 to JPG or PNG. Note that converting to standard raster formats flattens the image; you preserve the visual heatmap but permanently discard the interactive temperature data. If you need raw data for spreadsheet analysis, converting to CSV is the best option. Drop your file here to view and convert it securely right in your browser - free, online, and without installing complex proprietary software.
Convert.Guru analyzes your IS2 file, detects the exact format, and lets you read the text inside.
Users also converted JPG, LS2, IS3, ZIP, IR, GPBENC, PDF, SOURCEIMAGE, PNG, CRDOWNLOAD, IS2D, IMAGES and JPEG files.
If you want to convert IS2 file to JPG, BMP, PNG, PDF, GIF, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use Fluke SmartView or similar software from the "Radiometric Thermal Image Storage" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to IS2, try Fluke SmartView or another comparable tool in the "Radiometric Thermal Image Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IS2 converter.
