If you have a web page (HTML code or an .html file) and want a link someone can click to see it, you need HTML hosting — an HTML to URL converter. If you have text with spaces or symbols that must go inside a URL (like ?q=fish & chips), you need URL encoding — the URL encoder. A third, rarer meaning is a data URL, which packs a file into the link itself.
Meaning 1 — Publish HTML at a URL
Input: <h1>Hello</h1>… or index.html. Output: https://hello.htmltourl.dev/. The HTML is stored on a server and the URL points to it. Anyone opening the URL sees the rendered page. This is what people mean in nine cases out of ten — sharing an AI-built page, a project, a prototype.

Meaning 2 — Encode text for use in a URL
Input: fish & chips. Output: fish%20%26%20chips. Nothing is hosted; the text is rewritten so it can safely sit in a query string or path. Developers search "html url encode" when building links in code or debugging a broken parameter.

Meaning 3 — Put the file inside the URL (data URL)
Input: an image or HTML. Output: data:text/html;base64,PGgxPkhlbGxvPC9oMT4=. The whole content travels in the link. Useful for embedding images in a single HTML file, but browsers block opening data:text/html links directly, so it is not a way to share pages any more.

Bonus meaning — HTML code for a link
Some people want the <a href="…"> tag that turns a URL into a clickable link on a page. That is the link code generator.
