Preview images deserve their own workflow

Open Graph and card images often look wrong when people simply reuse a random banner or screenshot. This page helps users create cleaner share-preview images with safer spacing and better proportions for links and articles.

Important limitation

This tool resizes and frames existing images, but it does not generate text overlays, compose titles, or create full social banners from scratch.

Common mistakes

  • Using an image with important elements too close to the edges
  • Reusing a portrait image for a wide preview without enough background space
  • Forgetting that different platforms may crop previews differently

Privacy notes

  • Resizing runs in your browser during normal use
  • Your source image stays on your device while preview assets are created

FAQ

What is an Open Graph image?

An Open Graph image is the preview image social platforms often show when someone shares a page link. It affects how the shared page looks on Facebook, LinkedIn, and other platforms.

Can I use this for Twitter cards too?

Yes. The tool includes a larger Twitter-style preview preset in addition to Open Graph sizing.

Why add padding around the image?

Padding reduces the risk of important parts sitting too close to the edges of a social preview, which can look cramped or get cropped awkwardly.
