All processing happens locallyWhat this tool does
Version Comparator is a version comparator following Semantic Versioning rules, implements the standard table both ways and locates invalid bytes instead of silently dropping them.
A common mistake is comparing versions as decimals: 1.10 and 1.9 look like 1.1 and 1.9, but segment-wise 10 > 9 so 1.10 is newer. A pre-release such as 1.0.0-beta.2 sorts below the matching release, as SemVer requires.
How to use it
- Paste or type your content into the input field at the top, or press the sample button to load demo data.
- Adjust the options below the input, such as output format, separators, letter case or precision.
- Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
- When the result looks right, use the copy button in the corner, or download it as a local file.
Tips and notes
Clean up stray spaces and line breaks before pasting for more accurate results.
FAQ
1.10. Versions compare segment by segment, and 10 > 9 — unlike decimals.
No. The tool strips a leading v or V, so v1.2.3 equals 1.2.3.
1.0.0. SemVer puts pre-releases below the matching release, so the final release is always the upgrade.
The bytes are invalid in the chosen encoding — usually the wrong codec.
Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.
No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.
Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.
Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
