Extract text from Source code diff files (PATCH)
To convert PATCH Diff files to another format, you need Git or other Developer software.
To convert other file formats to the "Source Code Difference" file type, you need software like Git or a similar tool.
A .patch file is a text file that contains a detailed list of differences (a "diff") between two sets of source code. Developers use these files to share code updates, bug fixes, or new features without having to transmit the entire codebase. They are heavily utilized by version control systems like Git and GNU diff/patch utilities, as well as modern IDEs like IntelliJ IDEA. Occasionally, .patch files act as binary difference patches for software updaters (like bsdiff or Steam) or even compressed game updates for titles like The Sims 4.
The main disadvantage of a .patch file is its strict dependency on the original file state. It is not a standalone executable; it only contains relative changes (added or removed lines). To use it, you must apply it to the exact original source files using command-line tools like git apply or patch. If the underlying code has been modified by even a single space, the patch will likely fail or "reject." For non-developers, opening a raw .patch file in a standard text editor yields a confusing wall of symbols (+, -) and metadata without proper syntax highlighting. Binary and game .patch files are completely unreadable and useless without the exact target executable to patch.
Because raw .patch files are difficult to read or share with non-technical stakeholders, converting them is highly recommended. Convert .patch to TXT or MD (Markdown) to cleanly review code changes in any web browser. If you need a permanent, unalterable record for compliance or a formal code review, convert it to PDF.
Convert.Guru analyzes your PATCH file, detects the exact format, and lets you read the text inside.
Users also converted PATCH_0, ZIP, XDELTA, DIFF, GPU_RESOURCES, STREAM, TXT, IPS, PDF, PNG, EXE, WAV and JPG files.
If you want to convert PATCH file to MP3, XDELTA, IPS, JS, TS, PY, JAVA, CPP, C, CS, PHP or RB, you can use Git or similar software from the "Source Code Diff Update" 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 PATCH, try Git or another comparable tool in the "Source Code Diff Update" 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 PATCH converter.
