Thumbnail research made easy

The cover frame is what makes someone stop scrolling. Saving the thumbnails of top-performing reels in your niche lets you spot patterns — framing, text placement, colour — and design better covers of your own. It's the same reverse-engineering that works for hashtags, applied to visuals.

Full quality, straight from the source

The image comes directly from Instagram's CDN, so it's exactly the resolution Instagram stores — no re-compression, nothing added.
