Free online Cover Sizes: Crop one image into all platform cover sizes. No software installation, works right in your browser, completely free.
Cover Sizes crops one image into every platform cover size at once — WeChat banners, Xiaohongshu covers, Bilibili and Douyin covers, YouTube thumbnails and more. Upload one photo and download a ready-to-post set, with a focal point control that keeps the important part visible in every crop.
Prepare one photo as covers for WeChat, Xiaohongshu, Bilibili and Douyin in a single pass.
Crop a striking 1280×720 thumbnail from a frame or portrait while keeping the subject centered.
Reuse one product photo across storefront banners and social covers without manual cropping.
One good product or portrait photo can feed every channel you publish to. Setting the focal point once prevents the classic problem of heads or logos being cut off in square and banner crops. Download all sizes as a ZIP to keep your publishing folder tidy.
