PNG to HEIC Converter
Understanding HEIC encoding and alternative solutions
About Browser-Based HEIC Encoding
HEIC (High Efficiency Image Container) is Apple's proprietary image format. While we can easily decode HEIC to other formats, encoding images to HEIC in a web browser presents significant technical challenges:
- Browsers don't natively support HEIC encoding
- Requires large WebAssembly libraries (~2-5MB)
- Complex low-level API integration needed
- Potential performance issues and slow conversion
To maintain a fast, lightweight experience, we've chosen not to implement browser-based HEIC encoding at this time.

❓Frequently Asked Questions
Why can't you convert PNG to HEIC in the browser?
HEIC encoding requires specialized libraries that would significantly increase our app size and slow down performance. The system tools mentioned above provide better, faster results.
Will you add this feature in the future?
We're monitoring technology developments. If efficient browser-based HEIC encoding becomes available, we'll consider adding it. For now, the alternatives above work excellently.
