How to use it
- Pick a quality. Standard suits almost everything.
- Choose your HEIC photos, or drop them on the box. You can pick many at once.
- Download each JPG, or all of them as one ZIP.
Why iPhones use HEIC
HEIC often stores a photo in around half the space of a JPG at similar quality, so iPhones use it by default. Many websites, government portals and older programs still only accept JPG or PNG, which is why conversion is needed.
Opening HEIC files without converting
Macs and iPhones open HEIC files natively. On Windows, the Photos app can open them once the HEIF and HEVC extensions from the Microsoft Store are installed (the HEVC one may cost a small fee). Converting to JPG is simpler when you need to upload, email or print the photo, because almost every website and printer accepts JPG.
Limits
- Location and camera details are not kept in the JPG. That's usually what you want for uploads; keep the original if you need them.
- Live Photos and bursts convert to a single still image.
- Large batches on phones can run out of memory. Convert in smaller groups if the page slows down.
- The first conversion takes a few seconds longer while the decoder (about 1.5 MB) loads.
Questions
Can I stop my iPhone saving HEIC in the first place?
Yes. In Settings, open Camera, then Formats, and choose "Most Compatible". New photos are then saved as JPG. Photos you've already taken stay HEIC.
My iPhone uploads a JPG to some websites anyway. Why?
When you pick a photo in Safari, iOS often converts it to JPG automatically. Sharing files from the Files app, AirDrop or a computer usually keeps the HEIC original, which is when you need this tool.
Will the JPG look worse?
At Standard or High quality the difference is very hard to see. JPG files are bigger than HEIC for the same photo.
