What HTML Publishing actually does

Clean pasted HTML for publishing while preserving lists, links and table semantics; preview changes safely.

Common questions

What does HTML Publishing support?
Semantic HTML subset. Active content, remote media and formatting attributes are removed. Lists, links and table headers remain. Source is retained for comparison and undo; previews run in a script-free sandbox. HTML validation reports parser diagnostics, not full standard conformance.
Does HTML Publishing upload my content?
Your content stays in page memory. Processing runs locally; navigation or reload clears it.
What limits apply to HTML Publishing?
256 KiB combined input; 5,000 input rows; depth 40; 10,000 nodes; 2 MiB output. Processing stops after 3 seconds; worker startup allows 15 seconds.
