Frequently asked questions
What formats can be converted to HTML?
Markdown (.md), plain text, and certain document formats can be converted to HTML. See the specific converter pages for each source format.
Is the output HTML5-compatible?
Yes. The converter produces standard HTML5 markup with semantic elements like headings, paragraphs, lists, and code blocks.
Will inline styling be added to the HTML?
The output is clean HTML without inline CSS styles unless the source format contains style information. You apply your own CSS separately.
Can I convert Markdown to HTML?
Yes. Markdown is the most common conversion to HTML. BoltConverter has a dedicated Markdown to HTML converter.
Is the HTML output safe to include in a web page?
The output reflects the input content. If the source contains scripts or unsafe HTML, those would appear in the output. Always review HTML before embedding it in a live page.
