Tool comparison
Markdown Preview vs HTML Entities vs Text Diff: which tool should you use?
Compare the purpose, output, and best use case for each utility before choosing the fastest workflow.
Markdown Previewer is the best starting point when your task is: Write Markdown and inspect a sanitized live HTML preview with common syntax, copyable HTML, and local processing. If your source or destination format differs, one of the alternatives below may save an extra conversion step.
| Tool | Category | Best for | Example workflow |
|---|---|---|---|
| Markdown Preview | Text | Write Markdown and inspect a sanitized live HTML preview with common syntax, copyable HTML, and local processing. | Preview headings, lists, links, and code blocks before committing documentation. |
| HTML Entities | Converters | Convert text to HTML entities and decode named or numeric entities back into readable characters. | Encode <div> as <div> before placing it in documentation. |
| Text Diff | Text | Compare original and revised text with line-by-line additions, removals, statistics, and copyable diff output. | Compare an original paragraph with a revised version before publishing. |
Decision guide
Choose Markdown Preview when the input and desired output already match its core job. Choose HTML Entities or Text Diff when you need a related conversion, inspection, or editorial workflow. All three are free, browser-based, and safe for private data because they do not upload tool input.
