무료 링크 미리보기 도구

오픈 그래프 및 소셜 메타데이터(채팅 앱에서 링크를 공유할 때 표시되는 것과 동일한 종류의 제목, 설명, 이미지)를 가져오려면 공개 URL을 붙여넣으세요.

공유하기 전에 Facebook 게시물, 기사 또는 랜딩 페이지가 어떻게 보이는지 확인하는 데 유용합니다. 비공개 또는 로그인 전용 페이지는 메타데이터를 반환하지 않을 수 있습니다.

Frequently Asked Questions

What is a link preview?
A link preview shows the title, description, and thumbnail image associated with a URL - the same metadata that appears when you share a link on social media, Slack, or messaging apps.
Where does preview data come from?
Dokall fetches the URL and reads Open Graph tags (og:title, og:description, og:image), Twitter Card meta tags, and standard HTML title and description elements. Sites without these tags may show limited preview data.
Why might a preview be missing or wrong?
The site may block automated fetching, require JavaScript to render meta tags, have no Open Graph tags configured, or return different content to bots vs browsers. Some sites intentionally restrict preview crawlers.
Can I use this in my own app?
Yes. Install @dokall/link-preview from npm (https://www.npmjs.com/package/@dokall/link-preview). It is MIT-licensed, zero-dependency, and the same engine behind this tool.
Can I check if a link is safe before clicking?
Link preview helps you see where a URL leads before visiting. Dokall shows the final URL, title, and description. For QR codes and shortened links, combine with the QR Code Scanner which flags suspicious patterns.
Is the URL I check logged?
Dokall fetches the URL server-side to extract metadata. Avoid checking URLs containing private tokens, session IDs, or sensitive query parameters.
