About Diff Checking
A diff checker compares two texts and highlights the differences between them. Green highlights show additions, red highlights show deletions, and unchanged text remains normal. This is particularly useful for comparing code versions, text revisions, or any content that needs detailed comparison.

Frequently Asked Questions
How does the diff checker work?
The diff checker compares two texts line by line, identifying additions, deletions, and modifications. It uses advanced algorithms to highlight changes and provide detailed comparison results.
What file types are supported?
Our diff checker supports any text-based files including code files, configuration files, documentation, and plain text. Binary files are not supported.
Is there a size limit?
The tool can handle files up to several megabytes in size. For very large files, we recommend splitting them into smaller chunks for better performance.
