To convert other file formats to the "Intermediate Build Artifact" file type, you need software like GCC or a similar tool.

About I files

The .i file extension is a technical chameleon, most legitimately serving as a Preprocessed C Source File. These are intermediate artifacts generated by compilers like GCC or Microsoft Visual Studio just before the actual compilation phase. Unlike standard C or CPP files, a .i file has already run through the preprocessor: all macros are expanded, comments are often stripped, and header files are physically merged into the text.

Developers typically only generate these to debug complex macro errors, meaning they are rarely meant for long-term storage or distribution. They are large, verbose, and unwieldy for standard editing. Additionally, users in version control environments may encounter .i files as Mercurial Revlog Indices - binary files used by Mercurial to track changes. These are strictly for system use and will appear as gibberish if opened in a text editor.

Common Friction Point: A significant number of users (roughly 24%) report finding .i files that are actually renamed PDF documents or JFIF images, likely due to download errors or browser caching mishaps.

Conversion Recommendations:

For Debugging Code: Convert (or simply rename) to C or TXT to view the expanded source in a standard code editor like VS Code.
For Documents: If the file is not code, try converting it to PDF or JPG. Often, simply renaming the extension from .i to pdf fixes the issue instantly.
For Archiving: Compress these files into a ZIP, as preprocessed text compresses extremely well.

The I 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 I converter.
