Telegram generates link previews by fetching Open Graph tags server-side through its `TelegramBot` crawler. It supports both standard OG tags and Twitter Card tags, with the `twitter:card` value controlling whether a preview shows a large image or a small thumbnail.

This guide covers how TelegramBot crawls your pages, which tags it reads, image sizing and format requirements, how to clear cached previews with @WebpageBot, and the most common issues that prevent previews from appearing.
