About this tool
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It produces smaller files than JPEG, but Chrome, Firefox, Windows Photos (without an extension) and many upload forms cannot open it. This tool decodes HEIC in your browser using the open-source libheif library, then saves standard JPEG or PNG files.
To stop your iPhone creating HEIC files, go to Settings › Camera › Formats and choose Most Compatible. Photos you AirDrop or email are often converted automatically, but files copied by cable or cloud usually stay HEIC.
Good to know
- Up to 50 photos at a time, 40 MB each.
- Live Photo motion and depth data are not kept; you get the still image.
- Location and camera metadata are not copied to the converted file.
- The first conversion downloads a 3 MB decoder, so it takes a few extra seconds.
