HEIC to JPG
HEIC (High Efficiency Image Container) is the format iPhones save photos in by default since iOS 11. It stores roughly the same picture quality as JPG in about half the space — but many Windows apps, older editors and most web uploads still reject it.
Option 1 — stop creating HEIC in the first place
On iPhone: Settings → Camera → Formats → Most Compatible. New photos are captured as JPG. Also check Settings → Photos → Transfer to Mac or PC → Automatic, which converts HEIC to JPG when you copy photos off the phone.
Option 2 — convert files you already have
- macOS: open in Preview → File → Export → Format: JPEG. Batch-select many files first.
- iPhone/iPad: open the photo → share → Copy Photo, or use Shortcuts with the "Convert Image" action to batch-export JPG.
- Windows 10/11: install the HEIF Image Extensions from the Microsoft Store, then open the file in Photos and use Save as → JPG.
- In the browser (fastest, any device): our image converter opens HEIC directly in Chrome, Edge, Firefox and Safari — add one photo or a whole batch, choose JPG, PNG, WebP or AVIF, and download. Nothing is uploaded; everything happens on your own device.
Which quality should you pick?
JPG at quality 80–85 is visually indistinguishable from the HEIC original for photos and keeps files small. If the picture is going on a website, convert to WebP or AVIF instead — see WebP vs AVIF. After converting, you can compress the JPG or remove camera and location information before sharing.
Does converting lose quality?
Slightly — both formats reduce some image data to keep files small. The difference is normally not visible at sensible quality settings, but keep the HEIC originals if the photos matter. Expect JPG files to be roughly 1.5–2× larger than the HEIC source.
