Open Graph Image

Slidev allows you to set the Open Graph image via the seoMeta.ogImage option in the headmatter:

---
seoMeta:
  ogImage: https://url.to.your.image.png
---

# Your slides here

Local Image

If you have ./og-image.png in your project root, Slidev will grab it as the Open Graph image automatically without any configuration.

Auto-generate

Since v52.1.0, Slidev supports auto-generating the Open Graph image from the first slide.

You can set seoMeta.ogImage to auto to enable this feature.

---
seoMeta:
  ogImage: auto
---

It will use playwright to capture the first slide and save it as ./og-image.png (same as slidev export). You may also commit the generated image to your repository to avoid the auto-generation. Or if you generate it on CI, you might also want to setup the playwright environment.
