When someone shares a URL in a LINE chat, Linespider/1.1 fetches the page to generate a link preview. LINE is notably selective about Open Graph tags – it reads only og:title, og:description, and og:image, ignoring all other OG properties. Linespider does not execute JavaScript, respects robots.txt, and can download pages up to 20MB in size.
This guide covers how Linespider works, the three tags it supports, image handling, LINE’s official cache-clearing tool, and common issues with link previews in LINE chats.
