About this tool
Why image size matters on social media
Each platform crops and compresses images differently. Upload the wrong shape and the platform will cut off heads, text or logos for you. Upload an image that is too small and it will look blurry on large screens.
Resizing to the recommended dimensions gives you control over what people see. The blurred-background option is especially handy for posting a landscape photo as a story, because the whole photo stays visible without plain bars above and below.
