A cover image (also called a thumbnail) is the image shown for a video before it's played. Instead of relying on a platform's auto-generated thumbnail, Postpone lets you choose exactly how your video should look before someone taps play.
Supported Platforms
Cover images are supported on:
- TikTok
On TikTok, you can only choose a frame from the video itself — TikTok doesn't support uploading a custom image as a cover.
Ways to Choose a Cover Image
- Pick a frame from the video — Drag the slider to scrub through the video and select the exact frame you want to use.
- Upload or select a custom image — Use an image from your device or your Content Library. This option isn't available for TikTok.
Adding a Cover Image While Scheduling a Post
- Navigate to Create a Post and upload or select a video.
- Hover over the video in the media gallery and click the cover image icon.
- Choose a cover using either method:
- Drag the slider below the video preview to pick a frame.
- Uload a custom image or select one from your Content Library.
- Click Save Cover Image.
Cover images can be set from within the post composer for Instagram, Facebook, TikTok, Pinterest, and LinkedIn.
On Instagram, the cover picker is only available for Reels and single-video feed posts (which publish as Reels). On Facebook, it's only available for Reels.
Adding a Cover Image From the Content Library
- Navigate to the Content Library.
- Find the video you want to update.
- Click the actions menu (⋮) on the video, then select Add cover image (or Change cover image if one is already set).
- Choose a cover using either method described above.
- Click Save Cover Image.
A cover image is saved on the video itself, so it applies everywhere that video is used — across posts, platforms, and future reuses of the same video from your Content Library.
