After updating your iPhone to iOS 11, you may have noticed that your photos are all .heic files instead of the ubiquitous .jpeg. If you’re rather go back to shooting JPEG for now until you feel more ready to make the switch, it’s actually extremely easy to do.
To switch back from .heic (pronounced “heek”), simply open up your iPhone’s Settings and hit Camera.
In the Camera settings, tap the Formats option.
On the Formats screen, select Most Compatible instead of High Efficiency.
High Efficiency makes your camera shoot HEIF and HEVC formats, which can cut your storage in half without sacrificing image quality. The problem is, JPEG is much more universally compatible with popular photo software.
“Hopefully, this is only something we will have to do in the short term,” Cheng writes. “An OS-level change this big should encourage major software and service providers to finally support new file types and codecs.”
Until things catch up with Apple’s switch, you can switch to Most Compatible to continue shooting in JPEG for photos and H.264 for video, allowing you to continue using your existing workflow.
Update: Apple has a JPEG converter built into iOS 11 photo transferring as well. If you go to Settings and then Photos, make sure the “Transfer to Mac or PC” option is set to Automatic. This should make your iPhone photos transfer to your computer in a compatible format (e.g. JPEG). We’ve reached out to Apple to see why this conversion doesn’t seem to be working properly with certain programs for certain people (e.g. Lightroom importing).
