Add clean, automatic numbering to all headings on any webpage.

Numbered Headings enhances readability by injecting hierarchical numbering (e.g., 1, 1.1, 1.1.1) into all <h1>–<h6> elements. Instantly understand the structure of long articles, documentation, tutorials, and technical content — without modifying the original page.

Features

Automatic hierarchical numbering for H1–H6. Works on all websites. Preserves original styling and layout. Helps with scanning long pages and tracking sections. Ideal for developers, students, researchers, and writers.

Why it’s useful

Clear numbering makes complex pages easier to navigate, improves readability, and helps with note-taking, documentation review, and outline verification.

Simple, lightweight, and privacy-friendly — no data collection, no configuration needed.
