Pretty-print vs minify
Pretty-printing adds consistent indentation and line breaks so nested HTML is readable — useful when debugging a page, reviewing a template, or cleaning up markup copied from a page builder that outputs everything on one line. Minifying does the opposite: stripping whitespace, comments, and line breaks to shrink file size for production, where readability doesn’t matter but every byte of page weight does.
Why embedded CSS and JS get formatted too
Real-world HTML files often carry inline <style> and <script> blocks. Formatting the surrounding HTML but leaving those blocks as a single unreadable line defeats the purpose — this tool runs dedicated CSS and JS formatters on those embedded blocks too, so the whole file ends up consistently readable.
Configurable indentation
Teams disagree on 2-space vs 4-space vs tab indentation — the formatter lets you set your preferred indent width so the output matches your project’s existing style guide instead of forcing one convention.
Why use UtilityApps for this
Formatting runs entirely in your browser with no signup — your markup is never uploaded to a server, which matters if the HTML contains unpublished or client-confidential content.
