About HEICtoPNG

HEICtoPNG is a free online tool that converts HEIC (High Efficiency Image Container) files to PNG, JPG, WebP, and BMP formats. Our mission is simple: make image conversion fast, free, and private.

Why We Built This

When Apple made HEIC the default photo format on iPhones, millions of people suddenly had photos they couldn't open on Windows, share on social media, or upload to websites. Existing conversion tools either required uploading photos to remote servers (a privacy concern), installing desktop software, or paying for a premium subscription.

We built HEICtoPNG to solve this with zero compromise: your files convert instantly in your browser using WebAssembly, with no server uploads, no signup, and no cost.

How It Works

Our converter uses libheif, the same open-source library used by professional tools like GIMP and ImageMagick, compiled to WebAssembly (WASM) for in-browser execution. When you drop a HEIC file into our converter:

1. The HEIC file is read into your browser's memory
2. libheif decodes the HEVC-compressed image data
3. The decoded pixels are drawn to an HTML Canvas
4. The Canvas exports to your chosen format (PNG, JPG, WebP, or BMP)
5. You download the converted file directly from your browser

At no point does your file leave your device. We don't have servers that handle uploads — the conversion is genuinely 100% client-side.

Our Tools

• HEIC to PNG — lossless conversion with transparency support
• HEIC to JPG — compressed output with adjustable quality
• HEIC to WebP — modern format with superior compression
• HEIC to BMP — uncompressed bitmap for legacy software
