HTML Tidy is a computer program and a library whose purpose is to fix invalid HTML and to improve the layout and indent style of the resulting markup.

It was developed by Dave Raggett of World Wide Web Consortium (W3C), then transferred to a SourceForge project. Its source code is written in ANSI C for maximum portability and precompiled binaries are available for a variety of platforms. It is available under the W3C license (a permissive, BSD-style license).

Examples of bad HTML it is able to fix:

• Missing or mismatched end tags, mixed up tags
• Adding missing items (some tags, quotes, ...)
• Reporting proprietary HTML extensions
• Change layout of markup to predefined style
• Transform characters from some encodings into HTML entities
