Convert Thumbnail cache files (THB) online for free
The converter easily converts your THB Thumbnails to various formats - free and online. No Leica Application Suite or or other Raster Image software needed.
To convert other file formats to the "Thumbnail Cache File" file type, you need software like Leica Application Suite or a similar tool.
The .THB file format primarily functions as an image thumbnail or cache file. Approximately 54% of these files are generated by trail cameras from Stealth Cam and Wildgame Innovations. Another 34% are utilized by the Leica Application Suite and LEAD Technologies as an image thumbnail cache. Occasionally, DVR or NVR security systems generate them as video thumbnail previews, while Arcadia Soft's Arcadia-TERMO software uses the .THB extension for building energy performance certificates.
The core disadvantage of the .THB format is its lack of native support. Operating systems like Windows, macOS, and iOS do not recognize the extension, prompting annoying "Choose a program to open this file" dialogs. Furthermore, because these are usually caching formats intended to speed up software gallery loading, the actual image data is typically low-resolution and highly compressed.
Despite the proprietary file extension, internal data structures often use standard formats. The camera and DVR thumbnails are frequently standard JPG or PNG files simply renamed to .THB. The Arcadia-TERMO certificate files are internally structured as ZIP archives. Users typically need to convert these files to JPG or ZIP to recover the viewable content or extract the data without installing the original specialized software.
Standard online converters usually fail to process .THB files because they rely solely on file extensions rather than analyzing the file header. Just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. Our platform will inspect the internal hex data. If our analysis detects a supported underlying format like JPEG, PNG, or ZIP, viewing or conversion may still be possible.

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 THB converter.
