Extract text from M4 files
To convert your M4 file to another format, you need GNU m4 or other Developer software.
To convert other file formats to the "Macro Source Code" file type, you need software like GNU m4 or a similar tool.
The .m4 extension primarily identifies a macro source file used by the GNU m4 processor, a powerful text-substitution tool standard on Unix and Linux systems. These files contain code templates and macro definitions used to generate complex scripts, most notably within the GNU Autoconf build system. A common drawback for users is that .m4 files are raw text scripts; they are not executable programs and cannot be "opened" in the traditional sense without a command-line processor or a code editor like Visual Studio Code.
However, a significant number of users encounter .m4 files that are actually mislabeled or truncated MPEG-4 multimedia files (intended to be MP4 or M4V). If your file is large (several megabytes or gigabytes), it is likely a video file masquerading as a macro script. For developer files, the best conversion target is TXT or PDF for documentation and easy viewing. For mislabeled video files, converting (or simply renaming) them to MP4 ensures playback compatibility with standard media players like VLC Media Player.
Convert.Guru analyzes your M4 file, detects the exact format, and lets you read the text inside.

If you want to convert M4 file to MP3, WAV, MP4, GIF, AUDIO, MOV, VIDEO, JS, TS, PY, JAVA or CPP, you can use GNU m4 or similar software from the "Macro Processing Script" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to M4, try GNU m4 or another comparable tool in the "Macro Processing Script" 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 M4 converter.
