Browser-based
⚠️ Browser limitation: HEIC encoding is not supported natively in any browser — it requires proprietary Apple codecs unavailable on the web platform. This tool converts your JPG to WebP format instead, which offers comparable or better compression and is supported on all Apple devices running iOS 14+ and macOS Big Sur+. For true HEIC output, use Apple Photos, Shortcuts (iOS), or ImageMagick on the command line.
Why Can't Browsers Create HEIC?
HEIC uses the HEVC (H.265) video codec for compression, which is covered by patent licences held by MPEG LA. No browser vendor has licensed HEVC encoding for client-side web use, so HEIC output from a browser is technically impossible without a native binary component. This is not a limitation of this tool specifically — it applies to all web-based converters.
WebP as a HEIC Alternative
| Feature | HEIC | WebP |
|---|---|---|
| Compression vs JPEG | ~50% smaller | ~30–40% smaller |
| Transparency | Yes | Yes |
| iOS / macOS support | iOS 11+ / macOS High Sierra+ | iOS 14+ / macOS Big Sur+ |
| Browser encoding | Not possible | Fully supported |
For True HEIC Output
Use Apple Shortcuts on iPhone/iPad with the "Convert Image" action. On macOS, use the sips command: sips -s format heic input.jpg --out output.heic. On Linux/Windows, use ImageMagick with libheif installed.
