FAQs
Can whitespace be meaningful in HTML content?
Whitespace can matter in inline text, preformatted content and embedded code. Review those areas and test the rendered page before using a minified result.
Which inputs do I need for HTML Minifier & Markup Cleaner?
Use Paste Raw HTML Markup. The built-in examples show how those fields fit together.
What should I check before using this result?
Avoid minifying `<pre>` or `<textarea>` blocks that rely on literal whitespace. Check the assumptions and output against your intended task before relying on the result.
