HTML formatting FAQs
1. What does an HTML formatter do?
It adds proper indentation, line breaks, and consistent spacing to messy HTML code, making it human-readable (beautify). The minify version removes all unnecessary spaces and newlines to reduce file size.
2. Is my code safe?
Absolutely. All processing happens in your browser. We never transmit or store your HTML. You can even disconnect from the internet and it still works.
3. Can I upload an HTML file?
Yes! Use the "Choose File" button above to select an HTML file from your computer. The content will be loaded and you can format it immediately.
4. What encoding options are available?
We support all major encodings including UTF-8, ISO-8859 series, Windows code pages, and more. The encoding setting helps properly read uploaded files.
5. How do I change indentation?
Select your preferred indentation from the dropdown: 2, 3, 4 spaces, or tab delimited. The formatter will use your choice when beautifying code.
