About HTML Online

htmlonline.dev is a free, fast, private set of HTML tools built around one idea: everything you need to write, view, clean and convert HTML should be on one page, load instantly and never upload your code.

What makes it different

• Code and visual editing together. Write source code with line numbers and see a live preview, or switch to the visual (WYSIWYG) editor and type like a word processor — both stay in sync.
• All the tools on one domain. Viewer, formatter, minifier, cleaner, Word to HTML, HTML to text and Markdown, encoder, table generator, validator, HTML to PDF and a character code reference — no hopping between sites.
• Private. Every tool runs in your browser with JavaScript. We have no server that receives your HTML. Share links keep the code in the part of the URL after #, which browsers never send to a server.
• Free and no sign-up. No account, no paywall, no watermark.

Who it's for

Students learning HTML, bloggers and email marketers cleaning pasted content, support teams checking an .html attachment, and developers who need a quick formatter or minifier without opening an IDE.
