How It Works

Conversion Mechanics

Converting HEIC to PNG makes sense when you want a lossless intermediate file for editing — PNG won't add any further compression artifacts on top of what the original HEIC photo already has, unlike converting straight to JPG. It's also the right target if the image needs a transparent background afterward, since PNG supports an alpha channel and HEIC/JPG don't.

Why It's Private

Runs Entirely In Your Browser: Files are decoded and re-encoded strictly in local memory.
No Network Requests: The converter makes no calls to any server — check your browser's DevTools Network tab to confirm.
Nothing to Sign Up For: No account, no upload, and no server-side storage of your files.
Runs On Your Hardware: Processing uses your own device's CPU via Web Workers, not a remote server.
