Convert HEIC to JPG Online
Convert iPhone HEIC photos to JPG format — free, private, and instant. No files are uploaded to any server.
What Is HEIC and Why Convert to JPG?
HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads since iOS 11. It uses the HEIF standard with HEVC compression, producing files roughly 50% smaller than equivalent JPG images while maintaining the same visual quality. However, HEIC is not universally supported — Windows apps, older Android devices, web platforms, and many email clients cannot open HEIC files.
Converting HEIC to JPG ensures maximum compatibility. JPG (JPEG) is the most widely supported image format across all devices, operating systems, browsers, and applications. TweakFiles converts HEIC to JPG entirely in your browser using libheif — your photos never leave your device.
Common Use Cases
- Share iPhone photos on Windows or older Android devices
- Upload photos to websites that don’t accept HEIC
- Attach photos to emails for recipients who can’t open HEIC
- Import iPhone photos into photo editors that lack HEIC support
- Batch convert vacation photos for printing services
How TweakFiles HEIC Conversion Works
TweakFiles uses the heic-to library (powered by libheif 1.21) to decode HEIC files directly in your browser. The decoded image data is then encoded as JPG at your chosen quality level using the Canvas API. This approach supports all HEIC variants including those from the latest iPhones (iOS 18+).
How to Convert HEIC to JPG in 3 Steps
Upload HEIC Files
Drag and drop your HEIC or HEIF files into the drop zone, or click to browse. You can upload multiple files for batch conversion. Your photos stay on your device.
Adjust Quality
Use the quality slider to control the JPG output quality. Higher values produce larger files with more detail; lower values produce smaller files. The default 92% is a good balance.
Download JPG Files
Click download on individual files or use "Download All" to save everything. Files are named automatically based on the original filename.
