Common social media image sizes
Every platform recommends different image sizes: an Instagram post is a 1080×1080 square and a story is a 1080×1920 portrait; a Facebook cover photo size is about 820×312 and a shared post image is 1200×630; a YouTube thumbnail size is 1280×720; a Twitter/X header is 1500×500; a LinkedIn cover is 1584×396; and a Pinterest Pin prefers a 1000×1500 portrait. This tool has all of these built in — pick a platform, drag the crop box and export an image that fits the spec.
100% local processing, private by design
Unlike many online croppers that upload your images to a server, this tool runs entirely in your browser using the Canvas API. Your images are never uploaded, stored or sent to any third party — ideal for photos with personal information or commercial assets.
