Convert HEIC to JPG Without Uploading Files
QuickImageHub converts Apple's HEIC (High Efficiency Image Container) format to universal JPG entirely inside your web browser. Unlike iLoveIMG, Zamzar, or Convertio — which upload your photos to remote servers — our tool uses the heic2any WebAssembly library to process files locally. Your iPhone photos never leave your device.
Why Convert HEIC to JPG?
Since iOS 11, iPhones save photos in HEIC by default because it is roughly 50% smaller than JPG at the same quality. The problem: HEIC is not supported on Windows without extra codecs, most Android devices, older software, or many websites. Converting to JPG gives you a universally compatible file that works everywhere.
How to Convert HEIC to JPG — 3 Steps
- Select files: Click "Select Files" or drag HEIC images into the box above. Up to 50 files at once.
- Set quality (optional): Use the slider to set JPG quality between 60%–100%. Default 95% is ideal for most uses.
- Download: Save individual JPGs or all files as a ZIP archive.
