About Highlight PDF

Highlight PDF is built for people who need to mark key paragraphs for later reading sessions. Each request becomes a queued job with validated uploads, temporary object storage, and a time-limited download URL. When a conversion provider is not configured yet, the page still ships full SEO content and the API returns an honest NOT_ENABLED result instead of a fake file. Highlight overlays need an annotation engine before they are enabled.
