Convert Markdown to sanitized HTML source

Create copyable HTML source from one declared Markdown profile and raw-HTML policy.

Local processingNo sign-upNo content logging

Convert to HTML

Text stays in this tab. Markdown is capped at 500 KiB; pasted HTML uses a 256 KiB cap.

Sanitized HTML source

No result is placed in a URL, account, preset, API, or remote log.

What this tool does

Explicit-profile, bounded, local processing

This route produces an HTML artifact for review and copying. It is not a browser preview, template renderer, or claim that every platform will apply the same surrounding CSS.

HTML is an artifact, not an execution target

The result is presented as text. Active elements, event attributes, and network-loading media are not preserved.

Processing stays in this browser and is bounded by a 500 KiB Markdown limit, a 256 KiB HTML limit, a 1 MiB result limit, and explicit syntax-tree limits. The public tool never calls the developer API, fetches a URL, or stores a preset.

Raw HTML requires an explicit choice

Reject is the default. Strip removes raw nodes; sanitize parses the bounded fragment and keeps only the sanitizer's safe subset.
