About This Tool

This tool converts plain text into HTML-ready content by applying safe formatting rules. It accepts raw text, escapes HTML when requested, and outputs well-formed HTML suitable for web publishing.
It preserves or normalizes whitespace according to configuration to maintain readability.
Conceptually, the process normalizes line endings, divides input into blocks by blank lines to create <p> blocks, and converts internal newlines to line breaks when requested. When linkify is enabled, URLs are converted to anchor tags while preserving surrounding text. The design emphasizes safety, predictability, and simple, auditable output.
Target users include developers integrating user-generated text, editors preparing content for CMS import, and teams automating content pipelines. The tool's safe defaults minimize HTML injection risks and produce consistent markup across pages.
Core differentiators include explicit input/output contracts, option-level controls, and a straightforward, auditable transformation logic that avoids guessing formatting.

Frequently Asked Questions

Find Quick Answers

How does escaping affect the output?

If escape_html is true, all HTML special characters are escaped, preventing interpretation of tags and preserving text as content. This reduces injection risk but may require post-processing for markup needs.

Can existing HTML be preserved?

Existing HTML is escaped by default to ensure safety. If you disable escaping, the tool will treat input as HTML, which may render or ignore tags depending on the configuration and whitelist rules.

What happens to line breaks?

Line breaks can be preserved as
tags or converted to paragraph blocks (

) depending on wrap_paragraphs and newline_to_br options, enabling either compact or semantically structured output.

Is this tool suitable for production content?

Yes, for simple plain-text to HTML transformations with deterministic behavior. It is not a full Markdown processor or rendering engine; validate output in your production templates and adjust options accordingly.
