Resize an Image for Instagram Without Cropping
Upload the image, choose the required Instagram preset and select Fit without cropping. RapidTools keeps the complete photo visible and adds padding around it when the source ratio differs. You can choose the padding colour before downloading.
Instagram DP and Profile Picture Size
Use the 320×320px Profile Picture preset for an Instagram DP. The uploaded file is square, but Instagram shows it inside a circular frame, so keep faces, logos and important text near the centre.
