Apple introduced the HEIC (High Efficiency Image Container) format starting with iOS 11. It produces smaller files than JPG while maintaining the same image quality, which helps save storage space on your iPhone and iPad.
The problem? HEIC files aren’t universally supported. Many websites, email clients, and older applications still require JPG. If you’ve ever tried to upload an iPhone photo and hit a “format not supported” error, HEIC is likely the reason.
Photo Tamer sits in your Mac’s menu bar, always ready. Just drag your HEIC files onto the icon and get JPGs back instantly. There’s no app to open, no settings to configure, and no limit on how many files you can convert at once.
Unlike online converters, Photo Tamer processes everything locally on your Mac. Your photos never leave your computer — no uploading to servers, no privacy risks, no waiting for slow connections.
Coming back from a trip with hundreds of HEIC photos? Select them all, drag them onto Photo Tamer, and they’ll all be converted in seconds. Photo Tamer uses minimal CPU and memory, so your Mac stays responsive even during large batch conversions.
