About H files

A .H file is a standard C, C++, or Objective-C header file used to declare variables, constants, functions, and classes that are shared between multiple source files. While essential for compilation by tools like GCC or Clang, these files are strictly plain text source code. This can be a major source of frustration for documentation, archiving, or sharing with non-technical stakeholders who lack integrated development environments (IDEs) like Visual Studio Code or Xcode. Opening a .H file without syntax highlighting makes the logic difficult to parse, and printing raw code often results in formatting errors or loss of context.

To overcome these readability constraints, users frequently need to convert .H files into more universal formats. For formal documentation or technical specifications, converting to PDF preserves the layout and ensures the code is viewable on any device without specialized software. For web-based documentation or wikis, converting to HTML allows for syntax highlighting to be rendered directly in a browser.

Convert.Guru analyzes your H file, detects the exact format, and lets you read the text inside.

Users also converted CPP, HEADER, INO, C, HPDF, TXT, VCXPROJ, HEIC, ZIP, BIN, SO, TTF and JPG files.



The H 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 H converter.
