Usage Guide
Convert HTML↔Markdown locally as a bridge — expect manual cleanup.
1. Convert
Paste, convert, inspect headings/lists/links.
2. Lossy round-trips
Tables/custom HTML/scripts will not survive perfectly.
3. Scenes
Clip articles to MD; render README HTML for limited CMS editors.
4. Safety
Conversion is not XSS sanitization.
5. Related
Entity decode and HTML format can help before converting.
6. Accept
Check images, code fences, and heading levels.
FAQ
No. Both directions run inside the current page — HTML to Markdown via Turndown, Markdown to HTML via local parsing and rendering — so nothing leaves your browser, and there is no usage cap.
Yes. HTML to Markdown pulls web content into notes (e.g. clipping an article minus its ad shell) and runs on Turndown; Markdown to HTML renders output, e.g. previewing a README to paste into a backend that doesn't accept Markdown. GFM extended syntax is supported.
Yes — round-trip loss is the norm: table alignment, nested lists, custom HTML, comments, and scripts never survive intact. Treat it as a bridge, not a lossless archival converter; keep the source of record for important documents, and after converting check heading levels, lists, and links first.
Clean before you convert: removing navigation, scripts, and ad shells cuts most of the noise. Split large pages into segments, then spot-check that image URLs still resolve and code blocks weren't broken apart. HTML entities can be decoded first, and huge HTML can be formatted before converting for easier eyeballing.
No. The converter swaps syntax; it doesn't audit for XSS. Assume HTML from external sources carries malicious attributes, and never render unsanitized output as trusted content in production.
