When to use this HTML minifier
Use this HTML minifier when you need to compact a small markup example, embed a snippet, or prepare static HTML for sharing. It is designed for everyday web, data, and developer workflows where a quick browser-side result is more convenient than opening a heavy desktop application.
The best workflow is to paste a small representative sample first, confirm the output looks correct, and then process the full content if it is appropriate to handle in your browser.
