Frequently Asked Questions

Does the comparison work line by line or character by character?
The tool performs a line-by-line diff by default. You can also enable character-level diffing within changed lines to pinpoint exact word or character changes.
Can I compare code, not just prose text?
Yes. The text compare tool works equally well for source code, configuration files, JSON, CSS, and any plain text format.
Is there a size limit for the texts I can compare?
The comparison runs in your browser and can handle moderately large documents (several thousand lines). Very large files may benefit from a dedicated diff tool.

About Text Compare

The Text Compare tool on Utilko delivers a fast, visual diff of two text blocks directly in your browser. Color-coded highlighting makes it immediately obvious which lines were added, removed, or modified — no command line or developer tools required. Writers use it to review revisions, developers use it to spot configuration changes, and editors use it to compare drafts.

The underlying diff algorithm follows the standard Myers diff algorithm, the same approach used by version control systems like Git. This means the diff output is accurate, minimal, and clearly presents only the real differences rather than unnecessary surrounding context, making the review process as efficient as possible.
