Convert a file to TTI

To convert other file formats to the "Proprietary Tracing & Teletext Data" file type, you need software like Dolphin Imaging or a similar tool.


About TTI files

A .TTI file represents three highly specialized data types: an Enhanced Teletext Specification page used by legacy broadcast systems, a synthesizer instrument patch for TerraTec EWS64 XL sound cards, or a cephalometric tracing data file created by Dolphin Imaging software. The primary disadvantage of the .TTI format is its extreme obsolescence and proprietary nature. Teletext data requires niche viewer tools like VTX-wxTED, TerraTec patches are locked to discontinued 1990s hardware, and Dolphin Imaging files demand an active, expensive medical software license. These formats are completely inaccessible in modern web browsers or standard operating systems. Users usually seek to convert teletext .TTI files to standard text formats like TXT or HTML, TerraTec presets to universal WAV or SF2 (SoundFont), and Dolphin files to PDF or JPG for seamless patient record sharing. Because .TTI formats are closed and proprietary, standard online converters almost always fail to process them. Just drag and drop your file to convert.guru to identify the exact format version, view it, and convert it when possible. While complex proprietary files are notoriously difficult to open outside their original software, our tool can inspect the file's internal binary content and show extracted text blocks. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be easily possible.

Convert.Guru analyzes your TTI file, detects the exact format, and lets you read the text inside.

Users also converted GPX, WF1 and PTS files.
