It handles typical page-sized and component-sized HTML very well. Extremely large files (tens of thousands of lines) may format more slowly since everything runs on your device's browser rather than a server, but small to medium snippets format instantly.
It's designed to cleanly re-indent well-formed HTML. If your markup has unclosed tags or other structural issues, the tool will still try its best, but for badly broken HTML you may want to fix unclosed tags first for the cleanest result.
