Open Graph / Twitter Card Generator & Previewer
Preview safety, limits and privacy
Literal escaped meta tags only: website Open Graph type and Twitter summary or summary_large_image. Description may be empty; empty image URLs omit image tags. Title and page URL are required. HTTP(S) URLs only, no credentials, whitespace, backslashes, control characters or newlines. URL spelling is preserved, not fetched or canonicalized.
Both previews use local text and an image placeholder, never remote images, CSS, frames or executable markup. They are illustrative, not a live platform crawler or a guarantee of platform appearance, caching or image dimensions. Copy tags into your own page head after review.
Each input is limited to 512 UTF-16 characters. Native edits clip at 514 before ordinary Blazor transport; edits over 512 clear all inputs and stale tags/previews and block generation until valid re-entry or Clear. Clipped prefixes are never accepted. No external API or automatic payload storage is used. Interactive Auto server events traverse the Blazor connection; WebAssembly executes on device. Website active only; extension and Android are inactive metadata, not a hard deep-link access boundary.
