Extract text from Fax transmission records (EFR)
To convert EFR Fax records to another format, you need Panasonic PC-FAX or other Compressed software.
To convert other file formats to the "Fax Archive File" file type, you need software like Panasonic PC-FAX or a similar tool.
An .EFR file is primarily a Fax transmission record archive generated by Panasonic PC-FAX software. It is used to store logs, metadata, and the actual images of sent or received faxes processed by Panasonic multi-function printers and fax machines.
These files are natively handled by Panasonic PC-FAX, a legacy utility used in office environments for digital fax management. The main disadvantage of the .EFR format is its proprietary camouflage. Sharing an .EFR file with a client or colleague usually results in an "unrecognized file format" error, as it requires a specific, often outdated, software suite to open natively. Standard document viewers, mobile devices, and web browsers cannot read .EFR files directly, creating annoying bottlenecks when trying to access critical communication records.
The best conversion targets for .EFR files are PDF for universal document sharing, TIFF for high-quality, multi-page fax image retention, or ZIP for raw data extraction. Converting to PDF ensures that the fax can be opened on any device securely.
Most standard online converters fail with .EFR files because they do not recognize the extension and lack the specific parsers for Panasonic's formats. However, the technical reality is that the standard .EFR fax archive is simply a standard ZIP container in disguise. Our analysis detects the supported underlying archive format, bypassing the proprietary lock so you can extract the embedded fax images instantly. (Note: In rare cases - less than 1% - an .EFR file may be a legacy Encryptafile Private Key used by XenoSystems, which is pure cryptographic data and cannot be converted to documents)..
Convert.Guru analyzes your EFR file, detects the exact format, and lets you read the text inside.

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 EFR converter.
