Frequently asked questions
Is my input sent to a server?
No. Conversion happens inside your browser, and your input is not sent to any external server. HTML is also safely escaped.
Practical example and verification criteria
Markdown Preview: Distinguish counting, comparison, Markdown preview, and placeholder-text generation, then consider how character encoding, line endings, whitespace, case, Unicode combining characters, and language-specific word boundaries affect the result. Work on a copy of an important document and check autosave and export formats first.
Markdown Preview: For a quick check, start with # Title → <h1>Title</h1> as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.
Markdown Preview: Read the character, word, and line definitions or rendering rules, then use a short sentence, blank line, emoji, combining character, and code block to compare the count or display with expectations. A browser preview can differ from a publishing platform's Markdown extensions, fonts, and security policy, and placeholder text is not factual content, so recheck in the final environment.
Markdown Preview · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.
Markdown Preview · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.
Markdown Preview · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
