How It Works
Our converter tool handles format conversion and compression entirely in your browser. Upload any supported image format, choose your output format and quality settings, and download the converted file—all without uploading anything to a server.
For HEIC files (common on iPhones), the tool uses multiple decoding methods to ensure maximum compatibility across different HEIC variants.
What is HEIC? HEIC (High Efficiency Image Container) is Apple's default photo format on iPhones since iOS 11. It offers better compression than JPEG while maintaining quality, but isn't universally supported. Converting to JPEG ensures compatibility everywhere.
Key Features
📱 HEIC to JPG
Convert iPhone photos to universally compatible JPEG format.
🔄 Format Conversion
Convert between JPEG, PNG, and WebP formats.
📉 Compression
Reduce file size with adjustable quality settings.
🔒 Private
All processing happens locally. Your images stay on your device.

HEIC Conversion
HEIC files use different codecs depending on how they were captured. Our converter tries multiple methods:
- Native browser decoding: Safari has built-in HEIC support
- libheif-js: WebAssembly-based decoder for cross-browser support
Note: Some HEIC files use codecs not available in browsers. If conversion fails, try Safari (which has native HEIC support) or use Apple's Preview/Photos app to convert first.
Compression Quality
When converting to JPEG or WebP, you can adjust the quality level:
| Quality |

Typical Reduction |
| 100% (Maximum) |
Archival, printing |
Minimal |
| 85-95% |
High quality sharing |
30-50% |
| 70-85% |
Web images, social media |
50-70% |

Common Use Cases
- iPhone to PC: Convert HEIC photos to JPEG for Windows compatibility
- Web optimization: Convert PNG to WebP for smaller file sizes
- Email attachments: Compress large photos to reduce file size
- Social media: Convert to JPEG for universal platform support
- Archiving: Convert to PNG for lossless storage
Tips for Best Results
- Use JPEG for photos without transparency—smallest file with good quality
- Use PNG for screenshots, graphics, or images needing transparency
- Use WebP when you know your audience has modern browsers
- Start with higher quality (85%+) and reduce only if file size is critical
- For HEIC files, Safari typically provides the best conversion results
