What is a Diff Checker?
A diff checker (or difference checker) is a tool that compares two versions of text and highlights the differences between them. It shows what has been added, removed, or changed, making it easy to track changes in documents, source code, configuration files, and more.
Our diff checker provides both unified and side-by-side views, supports line-by-line, word-by-word, and character-by-character comparison modes, and offers options to ignore whitespace and case differences for more flexible comparisons.
