Frequently Asked Questions

Why can't browsers create true HEIC files?

HEIC uses HEVC (H.265) codec which requires licensing. Web browsers don't have built-in HEIC encoders due to patent restrictions. Check browser compatibility for more details.

Will the output file work on my iPhone?

The file will open on iPhone since it's actually PNG data, but you won't get HEIC's compression benefits. For genuine HEIC, use native iOS or macOS tools.

Is this converter still useful?

This tool is useful for testing, file naming, and understanding format differences. For production HEIC conversion, we recommend platform-native tools or our HEIC to JPG converter which works perfectly.

What's the best way to convert JPG to HEIC?

The most reliable method is using an iPhone or Mac. On iPhone, photos stay in their original format. On Mac, open JPG in Preview, go to File → Export, and select HEIC. According to MDN, true HEIC encoding requires system codecs.

Is my data safe when using this converter?

Yes! All processing happens locally in your browser. Your images never leave your device, ensuring complete privacy and security.

Are there desktop alternatives?

Yes! macOS Preview, Windows HEIF extensions, and command-line tools like ImageMagick with libheif can create genuine HEIC files with system codec access. You might also want to check our JPG to PNG converter for other format needs.
