HTML Formatting FAQs

Will this break my scripts?

No. Our parser is designed to respect <script> and <style> blocks, maintaining their internal integrity while formatting the surrounding markup.

Is there a limit on file size?

We support large HTML files (up to several MB) with zero latency, as all processing is handled by your local CPU.
