Extract text from Source code patches (DIFF)
To convert DIFF Patches to another format, you need GNU diffutils or other Developer software.
To convert other file formats to the "Source Code Patch File" file type, you need software like GNU diffutils or a similar tool.
A .diff file contains the exact line-by-line differences between two versions of a text file or source code project. Developers rely on this format to share updates, bug fixes, or code reviews without needing to transfer entire project directories. The file uses symbols like + for added lines and - for removed lines. You can generate and read these files using version control systems like Git or the GNU diff utility.
The main disadvantage of a .diff file is its poor readability for non-technical users. While it is technically just plain text, the strict formatting and metadata markers are highly confusing in a basic text viewer. Project managers, clients, or compliance auditors often struggle to review code changes in this raw state. Furthermore, to actually execute or "apply" the changes stored in a .diff file, you must possess the exact original source code files and know how to use command-line tools.
If you need to share code changes with a non-developer, you should convert the .diff file to a more accessible format. Converting to PDF locks the text layout, preventing accidental edits, and makes it easy to email to stakeholders. Converting to HTML allows you to preserve color-coded syntax highlighting for an easier review process in any web browser. Converting to standard TXT removes the default operating system association with complex developer tools, ensuring the file opens instantly on any device.
Because a .diff file is essentially a set of instructions for external source code, standard online converters often struggle to process or "render" them meaningfully. Our tools can inspect the raw text content of your .diff file, allowing you to view the code changes safely and convert the text into standard document formats.
Convert.Guru analyzes your DIFF file, detects the exact format, and lets you read the text inside.
Users also converted PATCH, JFIF, DFF, GITIGNORE, SAMPLE, HTML and PDF files.
If you want to convert DIFF file to PATCH, HTML, PDF, JS, TS, PY, JAVA, CPP, C, CS, PHP or RB, you can use GNU diffutils or similar software from the "Source Code Patching" 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 DIFF, try GNU diffutils or another comparable tool in the "Source Code Patching" 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 DIFF converter.
