HTML Formatter
Clean up unformatted, messy HTML markup into well-indented, readable code with customizable line wrapping. · Updated
HTML formatting turns scraped, emailed, or CMS-exported markup into reviewable structure without uploading customer pages. Indentation and wrap length make accessibility audits and class cleanup faster. Convert to Markdown when you need docs, or jump to CSS/JS beautifiers for embedded assets.
Common errors and fixes
Unclosed tag warning
Close void-safe tags properly. Prefer self-closing only where HTML allows (img, br, meta).
Attributes not wrapping
Lower Wrap line length so long class or data attributes break onto new lines.
Script/style content shifted
Embedded blocks indent with parent depth; preserve intentional template whitespace carefully.
Empty lines removed
Enable Preserve empty lines to keep section spacing between major layout blocks.
