Convert a file to C
To convert other file formats to the "Source Code File" file type, you need software like GNU Compiler Collection or a similar tool.
About C files
A .c file primarily contains source code written in the C programming language. It is a plain text file holding functions, logic, and variable declarations necessary for building operating systems, applications, and embedded firmware. You can open and edit these files using specialized code editors like Visual Studio Code or compile them using the GNU Compiler Collection (GCC). More information can be found on Wikipedia. Despite being foundational to modern computing, .c files have significant disadvantages when viewed outside a developer environment. They are uncompiled text, meaning they cannot be run directly by the operating system. Furthermore, opening them in standard text viewers often strips away syntax highlighting, making the complex code difficult to read or review for non-technical stakeholders. They also lack built-in formatting for printing or formal documentation. To solve these problems, you need to convert the file. For web sharing and code review, convert .c to .HTML to preserve color-coded syntax. For archiving or formal printing, convert to .PDF or .PDF/A. For generic text parsing, convert to .TXT.
Convert.Guru analyzes your C file, detects the exact format, and lets you read the text inside.
If you want to convert C file to F, VB, CPP, JS, TS, PY, JAVA, CS, PHP, RB, GO or RS, you can use GNU Compiler Collection or similar software from the "C Language Source Code" 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 C, try GNU Compiler Collection or another comparable tool in the "C Language Source Code" category.
The C 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 C converter.
