Good to know

What is a HEIC file?

HEIC is the photo format iPhones and iPads have used since 2017. It keeps the same quality as a JPG in about half the space. The catch is that Windows, Android, older Macs and lots of websites can’t open it without help, which is where JPG comes in.

How do I stop my iPhone taking HEIC photos?

Open Settings > Camera > Formats and choose Most Compatible. New photos are then saved as JPGs, though they take up about twice the space.

To keep HEIC on your phone but get JPGs on a computer, open Settings > Photos and, under “Transfer to Mac or PC”, choose Automatic.

Will the photos lose quality?

At quality 90 you won’t see a difference. JPG files come out a bit bigger than the HEIC ones, since JPG is the older, less efficient format. PNG loses nothing at all, but each photo can be 10 MB or more.

What about Live Photos?

A Live Photo is a HEIC still plus a separate short video. You get the still photo as a JPG. The moving part isn’t in the HEIC file, so it’s left out.

Does it keep the date and location?

No. The JPGs leave out the date taken, camera details and GPS location. That’s handy for sharing, but if you’re archiving photos and want the dates, use the iPhone’s own “Automatic” transfer setting above, which keeps them.

Why does the first photo take a moment?

Most browsers can’t read HEIC themselves, so the first time, yours downloads a HEIC reader from this site (about 0.5 MB). After that it’s quick. Safari on a Mac, iPhone or iPad reads HEIC itself, so it skips the download.

Are my photos uploaded?

No. Your browser reads each photo and makes the JPG right there on your device. Nothing is sent to us or anyone else, and it’s all gone when you close the page.
