About BDOC files
The .BDOC file is a digitally signed document container primarily used in Estonia to store files and their legally binding digital signatures. Based on the ETSI ASiC-E standard, it functions internally as a standard ZIP archive holding the payload and cryptographic data. To open and verify these files, users typically rely on the DigiDoc4 Client provided by the Estonian Information System Authority. The main disadvantage of the .BDOC format is its regional specificity and strict software requirements. Users outside of Estonia or those without the dedicated ID software cannot easily view the enclosed documents natively. Furthermore, editing a signed document breaks the cryptographic signature, rendering the container permanently invalid. To access the contents without specialized software, the best approach is to extract the .BDOC file into standard formats like PDF, DOCX, or ZIP. Be aware that extracting the files completely strips away the legal digital signature, leaving you with only the raw, unsigned document. Because .BDOC is a closed cryptographic container, standard online converters often fail to process it. It requires specific handling to bypass the signature layer and access the payload. If our analysis detects the supported underlying ZIP format, viewing or extracting the embedded files is still possible.
Convert.Guru analyzes your BDOC file, detects the exact format, and lets you read the text inside.
If you want to convert BDOC file to PDF, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE or ARJ, you can use DigiDoc4 Client or similar software from the "Digitally Signed Document Container" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to BDOC, try DigiDoc4 Client or another comparable tool in the "Digitally Signed Document Container" category.
The BDOC 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 BDOC converter.
