Convert PNG to HEIC without uploading your file

Convert a PNG image to HEIC locally in your browser. Transparency is preserved when the HEIC reader supports alpha.

HEIC can be much smaller than PNG for photographic or mixed-content images. Screenshots with flat colors may not shrink as dramatically, but the output can still be useful for Apple Photos and other HEIC-aware apps.

When to convert PNG to HEIC

Use PNG to HEIC when you need a high-efficiency image for Apple-centric workflows and want the conversion to stay private. If you need universal compatibility or exact lossless editing, keep the PNG original.

The encoder is loaded on demand from this site, runs as WebAssembly in your tab, and never sends the image bytes to a server.
