What is a HEIC file?
HEIC is the default photo format on iPhones. It saves space, but many Windows PCs, websites and apps can't open it. Converting to JPG makes your photos work everywhere.
Frequently asked questions
Are my photos uploaded to a server?
No. Conversion runs in your browser, so personal photos never leave your device.
Will I lose quality?
At 90% quality the difference is invisible for practically all photos. Choose PNG for lossless output (larger files).
How do I stop my iPhone saving HEIC?
Go to Settings → Camera → Formats and choose Most Compatible.
