Image File Size Checklist

Is it the right format? Photos should be JPEG or WebP. Is it the right width? Around 2048 pixels suits iPhone photos. Is it under the limit? Aim for 500 KB or whatever the destination specifies.

Is it oriented correctly, cropped cleanly and free of private metadata? Our compressor handles orientation and strips metadata automatically when it re-encodes the image.
