About Open Graph Tag Generator

Build Open Graph meta tags for social media link previews. Open Graph Tag Generator runs entirely in your browser — no installation, no uploads, and no data ever leaves your device.

Common use cases: control how links preview when shared on social media; add og:image and og:description to blog posts; optimize link previews for marketing campaigns. Whether you are debugging, prototyping, or building production code, having a fast and private tool for this task saves time compared to writing one-off scripts or using an online tool that logs your data.

Like every tool in Catalyst, this one is free forever, requires no login, and is safe to use with confidential data. All processing happens client-side via native browser APIs.
