Convert a file to BTF
To convert other file formats to the "Risk Analysis Diagram" file type, you need software like BowTieXP or a similar tool.
About BTF files
The .btf extension is shared by two distinct but highly technical formats: BowTieXP risk analysis diagrams and Olympus microscopy images.
1. BowTieXP Risk Diagrams: Created by Wolters Kluwer Enablon, these files store 'bow-tie' method risk assessment visualisations. The primary challenge is that these are proprietary project files, making them impossible to view without the specific, costly BowTieXP software. Users typically need to convert these diagrams into static formats like PDF or PNG to include them in safety reports, presentations, or compliance audits where stakeholders lack access to the source application.
2. Olympus BigTIFF Images: Generated by Olympus cellSens and VS200 slide scanners, this .btf variant is a BigTIFF container designed to bypass the 4GB file size limit of standard TIFFs. While excellent for high-resolution scientific data, they are unsupported by standard Windows viewers, web browsers, and most consumer editing tools like Adobe Photoshop. To share these images or use them in publications, users must convert them to standard TIFF, JPG, or PNG, often sacrificing some dynamic range for compatibility.
3. World in Conflict Game Data: A niche usage where .btf acts as a localization or text data container for the real-time strategy game World in Conflict. Gamers often seek to convert these to TXT to edit language strings or mod the game.

If you want to convert BTF file to SHP, KML, KMZ, GPX, GEOJSON, TOPOJSON, TIF, TIFF, ECW, SID, IMG or DEM, you can use BowTieXP or similar software from the "Risk Analysis & Scientific Imaging" category. In the File menu, look for Save As… or Export….
To convert LAZ, KMZ, DTM, CSV, DEM, PRJ, LAS, GPX, DSM, SHP, DBF or KML files to BTF, try BowTieXP or another comparable tool in the "Risk Analysis & Scientific Imaging" category.
The BTF Converter Story
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 BTF converter.
