Compatibility and privacy
Output passes through an HTML sanitizer. Remote images are blocked by default so preview does not leak an IP address, referrer, or tracking parameters to third parties.
✓ Documents stay in browser memory and are never uploaded.
Frequently asked questions
Is inline HTML supported?
Safe basic HTML may remain; scripts, iframes, forms, event attributes, and dangerous URLs are removed.
Why did a remote image not load?
For privacy, preview does not automatically connect to third-party image servers.
