FAQ

OGImageSize is a toolkit for creating and validating Open Graph social previews. It provides free tools to check image sizes (1200x630), generate images, create meta tags, and preview how links will look on Facebook, Twitter, and other platforms.

Yes, the first version is completely free and does not require user login or registration to access all core tools.

The core tools are: OG Image Size guide, OG Image Generator, Open Graph Preview, OG Image Tester, and a Meta Tags Generator. There are also platform-specific preview tools and guides.

The recommended default size for most platforms is 1200 pixels wide by 630 pixels tall (a 1.91:1 aspect ratio).

Social platforms need the image URL, title, description, and explicit width/height tags provided in the HTML meta tags to reliably render a preview. An image file alone is insufficient.

Use the OG Image Tester to diagnose common issues like relative image URLs, missing HTTPS, incorrect image dimensions in the tags, or a platform cache that needs refreshing.

Yes, there are specific guides for implementing Open Graph metadata and generating OG images in Next.js applications, with ready-to-use code examples.

Yes, there is a dedicated Twitter Card Preview tool to check how your link will appear as a large summary card on X/Twitter.

The safe zone refers to the central area of a 1200x630 image that will likely be visible across all platforms, as some may crop the edges. Important text and logos should stay within this zone.

No, the current OG Image Generator uses fixed templates to create clean 1200x630 PNGs. It is not an AI-based image creation tool.
