Convert BDF files online for free
The converter easily converts your BDF file to various formats - free and online. No BioSemi ActiveTwo or or other Data software needed.
To convert other file formats to the "Biomedical Signal Recording" file type, you need software like BioSemi ActiveTwo or a similar tool.
The .BDF extension represents two distinct but significant formats in technical fields. Most commonly, it indicates the BioSemi Data Format, a specialized 24-bit variation of the European Data Format (EDF) used for storing high-resolution EEG and biomedical signals. While excellent for capturing raw brainwave data, these files are effectively locked away from standard analysis tools; generic EDF viewers often fail to read the 24-bit structure, and the files are too complex for basic text editors. To process this data in MATLAB, Python, or Excel, researchers must convert .BDF to EDF+, MAT, or CSV formats.
Alternatively, in the design world, .BDF stands for Glyph Bitmap Distribution Format, an ASCII-based font standard developed by Adobe. These files define fonts as pixels rather than vectors. The major disadvantage here is scalability; unlike modern TTF or OTF files, BDF fonts become jagged and pixelated when resized. Users typically convert these legacy bitmap fonts to TrueType or OpenType formats using tools like FontForge to make them usable in modern operating systems and design software like Illustrator. Other less common uses include MSC Nastran Bulk Data files for engineering simulation and Altera Block Design files.
Use Convert.Guru to open and convert your BDF file.
Users also converted BFD, PDF, DBF, EEG, JPG, JPEG, ZIP, PNG, EDF, DOCX, FON, TTF and GDS files.
If you want to convert BDF file to TTF, PDF, ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2 or RAW, you can use BioSemi ActiveTwo or similar software from the "BioSemi EEG Data Storage" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to BDF, try BioSemi ActiveTwo or another comparable tool in the "BioSemi EEG Data 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 BDF converter.
