Frequently Asked Questions
How does the formatting work?expand_more
The tool parses your HTML structure in real time as you type. It identifies tags, attributes, and text nodes, then re-assembles them with consistent indentation based on your preference (2 or 4 spaces).
Can it minify my code for production?expand_more
Yes! Toggling the "Minify" button removes unnecessary whitespace and line breaks. This is ideal for reducing file size before deploying to a production server to improve PageSpeed scores.
Is there a character limit?expand_more
There is no hard limit imposed by ToolXero. However, extremely large files (over 5MB) may cause your browser to slow down momentarily during the parsing process. We recommend breaking very large HTML documents into sections if performance becomes an issue.
