FIX: How to Change Highlights Cover on Instagram, Edit in PC, Black Cover Story 2026

Long-press the highlight bubble showing the black cover, or open the highlight and tap the three-dot menu while it's playing. A sheet slides up from the bottom listing Remove from Highlight, Edit Highlight, Send, Boost Story, Share to Facebook story, and Archive Highlight.

Tap Edit Highlight. Inside that screen, look for a separate Edit Cover button next to the filmstrip of stories already in the highlight.

It's a distinct step from picking which stories belong in the highlight, and it's the one that swaps the cover image without touching the stories themselves. Removing and rebuilding the whole highlight is not necessary just to fix a broken cover.

If the cover still renders black after re-selecting an image, the usual cause is a stale cache holding onto a corrupted thumbnail rather than the file itself. How you clear it depends on the platform, and the two are not the same task.

On Android, open the phone's own Settings, go to Apps, select Instagram, and tap Storage. You'll see separate Total, App, Data, and Cache figures, and a dedicated Clear cache button that only removes temporary files without touching your login or posts. iOS has no equivalent per-app cache control, and Instagram hasn't built one into its iPhone app either.

The nearest thing is offloading the app: Settings, General, iPhone Storage, Instagram, then Offload App. This clears the app's stored data while keeping your documents, and reopening (or reinstalling) Instagram rebuilds it fresh.

With the cache cleared, go back into Edit Cover and choose a new image. Instagram crops highlight covers into a circle, so use a square or near-square source and center whatever needs to stay visible.

A wide landscape photo gets cropped unpredictably, which is its own way of making a cover look broken even once the black-box glitch is gone. Save the change and back out to your profile.

Your highlights sit in a row just under your bio and stats, with a plus-sign circle for new ones followed by your existing covers in order. That row is the fastest place to confirm the fix actually took, since a leftover black cover will be obvious next to every other thumbnail displaying fine.

Occasionally the glitch is tied to one specific app build or session instead of the cache. If clearing cache and re-uploading hasn't fixed it, repeat the edit from a different device: a computer browser if you were on a phone, or a second phone if one's available. Once the cover displays correctly there, switch back to your primary device; it typically syncs and resolves on its own within a few minutes.
