Markdown → HTML Converter

Paste Markdown and PocketSpry converts it to HTML source instantly in your browser. It supports common Markdown syntax — headings, emphasis, lists, links, images, blockquotes, inline and fenced code, tables, and more — and returns an HTML fragment (no page boilerplate) as text you can copy. Raw HTML in the source is escaped rather than passed through, and nothing is rendered or executed. Your Markdown is processed locally and not sent to PocketSpry’s AI service.

Convert Markdown to HTML instantly

Paste your Markdown and PocketSpry returns the corresponding HTML source, locally in your browser — no sign-up, no upload, and no waiting on a server.

Common Markdown syntax

It supports headings, emphasis and strong emphasis, ordered and unordered (and nested) lists, blockquotes, links and images, inline code and fenced code blocks, horizontal rules, tables, and strikethrough — standard CommonMark plus those common extensions.

HTML fragments, not full pages

The output is an HTML fragment — the elements your Markdown maps to — without <!doctype>, <html>, <head>, or <body> boilerplate, so you can drop it straight into an existing page or template.

Raw HTML is escaped

Any raw HTML in your Markdown source is intentionally escaped and shown as text, not passed through as live markup. This keeps conversion predictable and safe — a <script> tag in the source becomes escaped text, never an executable element.

Code stays code

HTML-looking content inside inline code or fenced code blocks is escaped and shown as code — it is never executed. Code is not syntax-highlighted (a fenced block may carry a plain language class).

Safe links

Normal links (such as https links) are converted to anchors, but unsafe executable link schemes like javascript: are not emitted as active links — the parser’s built-in link validation drops them.

Standard line breaks

A single soft newline inside a paragraph does not become a <br> (standard Markdown behavior); use Markdown’s hard line break (two trailing spaces) when you want an explicit <br>.

Private and browser-local

Your Markdown is converted locally in your browser. It is not sent to PocketSpry’s AI service, and neither your Markdown nor the generated HTML is sent to analytics.

Markdown → HTML vs HTML Formatter

This tool converts Markdown to HTML source. If you then want to pretty-print or minify that HTML, use the HTML Formatter & Minifier — this converter returns the parser’s HTML as-is rather than reformatting it.

No AI conversion

Conversion is done by a standards-based Markdown parser, not AI. The same Markdown always produces the same HTML.
