Yes, you can paste file contents directly or drag and drop files into the input panels for comparison. The tool handles text files of any size and supports common programming languages with syntax-aware comparison. This makes it ideal for comparing configuration files, source code, database dumps, and documentation before and after changes.
Yes, in addition to line-level differences, the tool highlights changes at the word level within modified lines. This granular highlighting makes it easy to spot exactly which words or characters changed, which is especially useful when comparing similar versions of documentation, API specifications, or configuration files with subtle differences.
Yes, toggling the whitespace option ignores differences in spaces, tabs, and indentation. This is particularly useful when comparing code formatted with different IDE settings or when trailing whitespace differences are not meaningful. You can focus on actual content changes without being distracted by formatting variations.
