Facebook and Instagram do not support using video files (MP4 or GIF) as Open Graph (OG) images. Open Graph tags require a static image in JPEG or PNG format for proper sharing previews.
1. Social Platforms Only Support Static OG Images
- Facebook and Instagram only use the
og:image tag to render a preview, and they require a static image (JPG, PNG, or WEBP). - Video files like MP4 or animated GIFs are ignored when assigned to
og:image. - Animated GIFs may appear static if used, but Facebook often converts or discards animations during scraping.
2. Webflow's Limitations with OG Media
- Webflow's Open Graph image URL field accepts only static image URLs.
- There is no built-in feature in Webflow to set a video as an OG preview.
- If you input a video or GIF URL in the OG field in Project Settings > SEO > Open Graph Image, Facebook will not render a preview correctly.
3. Workaround for Video Experience
- You can upload a cover image (thumbnail frame of the video) as the OG image, which links to a page containing the actual embedded video.
- This allows the social preview to still grab attention while conforming to platform limitations.
- Use Facebook’s Sharing Debugger to test how the OG image will render: https://developers.facebook.com/tools/debug/
4. Format and Size Recommendations
- Facebook recommends 1200 x 630 px JPG or PNG images.
- Keep the image under 5MB for best performance.
- Aspect ratio should be 1.91:1 for optimal rendering across devices.
Summary
No, you cannot use MP4 or GIF video files as Open Graph images for Facebook or Instagram through Webflow. Only static image formats (JPG, PNG) are supported. Instead, use a video thumbnail as the OG image and embed the actual video content on your page.
