What is a HEIC to PNG converter?

A HEIC to PNG converter takes Apple's HEIC/HEIF image format and converts it into the lossless PNG format. This tool decodes HEIC files entirely in your browser using WebAssembly, renders the image for preview, and exports it as a standard PNG with full quality preservation — all without uploading your photos to any server.
