HTML格式化与美化工具

为压缩或单行的HTML添加适当的缩进和换行进行格式化。

如何使用本工具

  1. 1

    Paste your minified or single-line HTML into the input box.

  2. 2

    Read the indented result that appears below as you type — there is no button to press.

  3. 3

    Select and copy the formatted output from the result panel.

  4. 4

    Spot-check anything with <pre>, <textarea>, comments, or inline scripts, since those are not handled perfectly.

什么是HTML格式化与美化工具?

压缩后的HTML是一长串字符:传输速度快,但无法阅读。本工具可还原压缩:每个元素单独占一行,子元素多缩进两个空格。空元素(img、br、input)保持在行内。输出仅为美观考虑,渲染效果完全一致。

常见使用场景

  • Expanding a minified production HTML page so you can read its structure during debugging.

  • Tidying a snippet copied from a browser's DevTools Elements panel before pasting it into documentation.

  • Re-indenting a fragment of email or marketing HTML that arrived as one long line.

  • Inspecting the nesting and tag hierarchy of unfamiliar markup at a glance.

  • Cleaning up generated or template-output HTML before committing it to a repository.

  • Teaching or reviewing HTML structure where consistent two-space indentation makes nesting obvious.

常见问题

它会保留<pre>内部的空白吗?
行内文本内容会被折叠。对于含有大量<pre>的标记,你可能需要手动恢复空白。
