Your file is converted locally in your browser using a WebAssembly HEIC decoder. It is never uploaded anywhere — the first conversion on a page load may take a few seconds while that decoder loads.
Turn HEIC photos from an iPhone into lossless PNG files. Chrome, Firefox and Edge have no built-in way to read HEIC files — only Safari does — so this page loads a small HEIC decoder (libheif, compiled to WebAssembly) to do the decoding locally, entirely on your device.
Choose PNG when you need a lossless copy, or when the image will be edited further and you want to avoid compounding compression artifacts.
Chrome, Firefox and Edge have no built-in HEIC decoder, so this page loads a small WebAssembly decoder (libheif) the first time you use it. After that it's fast.
Usually yes — PNG is lossless and typically produces larger files than HEIC's efficient compression.
No, everything happens locally in your browser, including the HEIC decoding itself.
