Facebook Cover Photo Crop Preview Tool

A quick utility that lets users see exactly how their cover photo will appear on mobile before uploading to Facebook. Solves the frustration of uploading a cover photo only to find it crops awkwardly on mobile.

Facebook's continued algorithmic push toward Reels and video has actually increased profile and Page optimization activity among small business owners and creators trying to maintain organic reach, keeping demand for basic profile-polish tools alive. No clear incumbent owns this specific niche, though Canva's Facebook cover photo templates with device previews come close enough to eat most of the casual user base. At $200–800/mo, the revenue ceiling reflects the reality that this is a one-and-done utility — users solve their problem in 60 seconds and have no reason to return or pay recurring fees, which makes that range optimistic unless there's an ad-supported or freemium upsell to broader social media sizing tools. The single most likely failure mode is that Canva and free browser extensions already solve this well enough that conversion from free to paid is essentially zero.
