OGP Preview

OGP (Open Graph Protocol) is a specification that controls how web page titles, descriptions, and images appear when shared on social media. Without proper OGP tags, shared links may display incorrectly or miss images entirely. This tool simulates how your OGP tags will render on four major platforms — Twitter (X), Facebook, LINE, and Slack — in real time as you type.

Twitter card supports both summary and summary_large_image types. You can specify language and region with og:locale, and og:type supports a wide range of content types including website, article, video, music, and book. Character counts with recommended limits are displayed for each field, and the preview accurately reproduces how titles and descriptions are truncated when they exceed platform limits. The built-in validation checks URL formats for og:image and og:url.

The completed OGP tags are automatically generated as HTML code that you can copy and paste directly into your page's head section. All processing runs entirely in the browser with no URL fetching or server requests. Ideal for web developers, bloggers, and marketers who want to optimize their social media presence and ensure consistent sharing across platforms.
