HEIC to PNG Converter

How it works

HEIC is decoded with libheif (compiled to WebAssembly), then re-encoded losslessly as PNG. PNG files will be significantly larger than the source HEIC because PNG is uncompressed, but quality is preserved exactly.

Frequently asked

When should I pick PNG over JPG for HEIC?

Choose PNG when you need lossless quality for print, editing, or graphics work. Choose JPG for casual sharing and the web — the file is 5–10× smaller.

Will the PNG be much bigger than the HEIC?

Yes, typically 5–10× larger. PNG is lossless and HEIC compresses heavily. If file size matters, convert to JPG instead.

Is anything uploaded?

No. The decoder runs in your browser as WebAssembly. Your photos never leave your device.
