Quick answerBoth are free online HTML editors with a visual (WYSIWYG) mode and an HTML cleaner. HTML Online adds a real code editor with line numbers and a live preview, share links, open/save, format and minify, and a dozen HTML tools on the same site, and never uploads your code. html-online.com is a simpler, visual-first editor.

What's the same
Both let you edit HTML visually without writing tags, both have a cleaner for pasted content (inline styles, classes, empty tags, spans), and both are free with no registration. If all you do is paste and tidy a block of text, either works.
Where HTML Online is different
- Code-first. A proper code editor with a live preview that runs your CSS and JavaScript, so it doubles as an online HTML compiler.
- Visual and code in sync. Type in the Visual tab and the source updates; type in the source and the visual view follows.
- Undo for clean-ups. Format, minify and clean can be undone, so you can experiment safely.
- Share and save. Copy a share link with the code inside it, or save the file with Ctrl+S.
- One site, every tool. Viewer, formatter, Word to HTML, validator and more, each on its own page with the same privacy.
Switching over
There's nothing to migrate: copy your HTML from html-online.com's source box and paste it into the HTML Online editor. Your document is autosaved in your browser from then on. The cleaning options use similar names, and the full list is on the home page under HTML cleaning options.
When html-online.com might suit you better
If you only ever edit visually and prefer a single large word-processor style canvas, html-online.com's layout is simpler. HTML Online's Visual tab does the same job inside a split view.
