HTML格式化與美化工具

為壓縮或單行的HTML加上適當的縮排和換行進行格式化。

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.

什麼是HTML格式化與美化工具?

壓縮後的HTML是一長串字元:傳輸速度快,但無法閱讀。本工具可還原壓縮:每個元素單獨占一行,子元素多縮排兩個空格。空元素(img、br、input)保持在行內。輸出僅為美觀考量,算繪效果完全一致。

常見使用場景

  • 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.

常見問題

它會保留<pre>內部的空白嗎?
行內文字內容會被摺疊。對於含有大量<pre>的標記,你可能需要手動恢復空白。
