Readable markup is easier to ship
This page focuses on a practical workflow: take messy HTML from real projects, make structure readable, verify output quickly, and hand off a clean file. It is designed for people who need reliable formatting without opening a full IDE or setting up a project.
Built for practical cleanup tasks
Use it when markup comes from CMS output, email templates, copied snippets, or generated sources. Once indentation is normalized, wrappers and nested blocks are easier to trace, and edits become less error-prone.
Preview sits next to formatted output so you can validate rendering before sharing, committing, or publishing. This reduces back-and-forth in reviews and helps teams discuss structure with the same readable baseline.

What this page helps you do
Each feature serves one goal: make HTML easier to review without changing intended output.
Normalize structure for review
Turn inconsistent indentation into a readable tree so nested containers are easier to audit. Example: before `<div><ul><li>Item</li></ul></div>` in one line, after a multi-line nested structure that reviewers can scan.
- Clean indentation makes HTML structure easier to scan.
- Preview formatted output for quick visual checks.
- Import/export support fits real file workflows.
- Runs in browser with no sign-up.
