HTML Editor help
Frequently asked questions
A little help, so you can get back to creating. Find answers about editing, saving your work and keeping it private.
Select a question to read the answer.
Are my documents uploaded to a server?
No. Documents are stored in your browser and are not uploaded. See the Privacy Policy for details about how the website itself is delivered.
Do I need to create an account?
No. There are no accounts. Open the editor and start working.
What is the difference between Safe HTML document and Original source?
Safe HTML document exports a complete .html file with active content removed. Original source exports your HTML exactly as written, without changes.
Why are some images not showing?
External images are blocked by default to protect your privacy. Use the Load external images button in the Visual editor panel to show them.
Will Tidy HTML delete my content?
No. Tidy HTML only removes the kinds of code you select, and you review every change before applying it.
What happens if I clear my browser data?
Documents saved in your browser are removed with it. Export important documents regularly as a backup.
What if the same document is open in two browser tabs?
The editor warns you about the conflict and lets you choose Load latest or Keep mine.
How are my documents saved, and can I use them on another device?
Autosave stores documents in IndexedDB in the current browser profile. Ctrl+S (Cmd+S on macOS) saves immediately. Check the save indicator for errors or conflicts. There is no cloud backup or device sync; export a document and open the file on your other device.
Can I recover a document after closing its tab?
Yes. Closing a document tab does not delete its saved document. Use Reopen closed tab to restore it. Documents cannot be recovered here after you clear browser site data or use Storage management > Clear all documents, so export important work first.
Which files can I open, and why has visual editing paused?
Open HTML file accepts .html, .htm and .txt files up to 3 MB. Complete HTML imports extract body content for review before applying. Documents over 300,000 characters remain editable in the HTML source panel, but visual editing pauses to keep the editor responsive.
Can I run JavaScript or build a complete website here?
This is an HTML body-fragment editor, not a website runtime or hosting service. Visual editing and previews remove unsupported or active content and block scripts. Original source exports can still contain scripts you entered; do not open untrusted source exports as websites.
Do I have to accept optional cookies to use the editor?
No. Reject optional keeps editing and essential document storage available. Optional permissions control remembered editor preferences and Google Analytics, not access to editing. You can change them later using Cookie settings in the editor footer.
