Apple's High Efficiency camera setting can save photos as HEIF/HEIC to reduce storage use while keeping visual quality, so older web forms may need a JPG copy.

Source-device FAQ
Should I use JPG or PNG for iPhone photos?
Use JPG for normal photos because it is widely accepted and smaller than PNG for camera images. Use PNG only when you need lossless output for graphics or screenshots.
Does this iPhone HEIC converter upload my photo?
No. The file is decoded and exported in your browser, so the selected iPhone photo does not need to leave your device.
