When a text comparison helps
A comparison is useful when two versions of a draft, contract clause, configuration file, or list have drifted apart and you need to see exactly what changed instead of reading both from top to bottom.
Choose the comparison level
Pixuna’s Compare Text tool offers three levels. Lines is best for code, lists, and configuration; a changed line shows as one removed line and one added line. Words suits prose, where a few words changed inside a long paragraph. Characters is the finest level and is helpful for spotting typos or a single changed digit, but it can look noisy on large edits.
Removed text is shown struck through with a red background and added text with a green background. Unchanged text is left plain.
Ignoring harmless differences
Turn on Ignore case when capitalization does not matter. In line mode, Ignore whitespace differences treats runs of spaces as equal, which helps when indentation was reformatted. If everything matches under your settings, the tool reports the texts as identical.
Limits to know about
The comparison runs entirely in your browser, so very large documents can be slow; the tool declines inputs beyond a size limit and asks you to compare smaller sections. It compares text only, not formatting, tracked changes, or images, so a Word document should be converted to text first. The DOCX to Text tool can do that.
