HEIC is a photo format common on iPhones. Windows browsers often cannot decode it, and this site will not add a decoder or upload the picture so a server can convert it. If the page says it cannot read the file, open the photo on the iPhone and export a JPEG, or use a codec you installed yourself on the PC. When a browser can decode HEIC, the JPEG is encoded locally. Expect the JPEG to be larger than the HEIC. That is normal. The small HEIC size was the point of the format.

HEIC photos on Windows is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.
