Free Online Text & Format Converter
🛠️ One box, every format: HTML, Markdown, Plain Text, Base64, URL encoding, Hex, Binary, JSON and case conversions. Everything runs in your browser — nothing is uploaded.
Why use this converter?
Everything in one box
No need for five different sites — HTML, Markdown, Base64, URL encoding, hex, binary, JSON and case conversions all live in a single tool.
Runs entirely in your browser
Nothing you paste is sent to a server. Conversion happens locally with JavaScript, so it's fast and private.
Free, no signup, no limits
Use it as many times as you like — it's a free alternative to paid text-conversion utilities.
Is my text uploaded anywhere?
No. All conversions run locally in your browser using JavaScript — nothing is sent to a server.
Does the HTML → Markdown conversion handle every tag?
It covers the common tags (headings, bold, italic, links, lists, code, blockquote). Very complex or malformed HTML may need manual cleanup afterward.
Can I convert Markdown back to HTML?
Yes — select "Markdown → HTML" from the dropdown. It supports the same common elements.
