Converting HEIC Photos to Lossless PNG Format
High Efficiency Image Format (HEIC) is Apple's standard photo container for iPhone camera shots. When editing photos in web applications or uploading to non-Apple software, converting HEIC to PNG ensures maximum quality retention without lossy compression artifacts.
Browser-Based HEIC Decoding
FreeFileTool decodes HEIC image streams locally inside your browser session using WebGL/Canvas rendering. Your photos are never transferred across the network to external servers, protecting your personal media.
Limitations & Usage Guidance
- Batch Sizes: For high-resolution 48MP ProRAW iPhone photos, we recommend converting up to 15 images at a time to prevent browser memory exhaustion.
- Live Photos: The primary high-resolution static photo frame will be extracted and converted to PNG.

To ensure fast initial page load times, the HEIC decoder library is lazy-loaded into your browser memory only when you select a HEIC file for conversion.
