Extract text from Photoshop cache files (TB0)
To convert TB0 cache files to another format, you need Adobe Photoshop or other Data software.
To convert other file formats to the "Thumbnail Cache File" file type, you need software like Adobe Photoshop or a similar tool.
A .TB0 file is a proprietary thumbnail cache used primarily by Adobe Photoshop and Adobe Bridge. These applications generate .TB0 files to store low-resolution previews of high-quality images. This caching system speeds up the display of image galleries in the file browser, preventing the software from rendering large files from scratch every time you open a directory.
The primary application that creates and manages these files is Adobe Photoshop. They are generated silently in the background and are typically hidden from the user by default system settings to prevent accidental modification.
The main disadvantage of the .TB0 format is that it is strictly a backend data container, not a standard viewable image file. It cannot be opened by web browsers, standard photo viewers, or even imported manually back into the software that created it. Users often stumble upon these files taking up unnecessary space on their hard drives and struggle to view their contents. Because it is a closed, proprietary format designed exclusively for machine reading, standard online converters fail to process it into usable images.
If you are trying to recover lost photos, the best conversion targets are standard JPG or PNG files. However, be aware that any extracted image will be small and low-quality, as the original high-resolution data is not stored in the cache.
This file format is difficult to open because only the original Adobe software engine natively parses the cache structure. If our analysis detects standard supported underlying formats - like hidden JPEG headers - viewing or conversion may still be possible.
Convert.Guru analyzes your TB0 file, detects the exact format, and lets you read the text inside.
If you want to convert TB0 file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use Adobe Photoshop or similar software from the "Thumbnail Cache 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 TB0, try Adobe Photoshop or another comparable tool in the "Thumbnail Cache 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 TB0 converter.
