Frequently asked questions

Which Markdown flavor?
GitHub-flavored Markdown via marked, including headings, lists, code blocks, links, images, and tables.
How accurate is HTML to Markdown?
Common elements are converted reliably. Complex layouts may need manual cleanup.
Local conversion?
Yes. Both directions run entirely in your browser - your content never leaves your device.
Is HTML to Markdown lossless?
No. Comments and the head, style, and script blocks are dropped, and only a fixed set of elements is mapped. Tables, nested lists, and inline styles usually need a manual pass afterwards.
What happens to code blocks?
A pre block becomes a fenced code block with the inner tags stripped and entities decoded, and inline code becomes backticks. The language is not carried over, so add it to the fence yourself.
