Optimal Image Size Guide by Platform

Each social media platform recommends different image ratios and resolutions. Uploading the wrong size can trigger automatic cropping that cuts off important subjects, or result in blurry images. This tool provides exact platform specs as one-click presets, so you can set the correct ratio instantly. Lock the aspect ratio, drag the crop box to frame your shot, then save as JPG, PNG, or WebP.
