Qr Code Decoder

QR codes are no longer just black-and-white squares on restaurant tables.

You took a photo on your iPhone, sent it to a friend on Windows, and they replied: "I can't open this." Welcome to the HEIC problem. Since iOS 11, Apple iPhones and iPads save photos as HEIC by default — a format that's smaller and higher quality than JPG, but that a huge amount of software still can't open. The fix is simple: convert HEIC to JPG, the format that works literally everywhere. This guide covers every method, on every device — Mac, Windows, iPhone, Android, Chromebook, and Google Drive — plus how to convert hundreds of files at once, and how to stop your iPhone making HEIC files in the first place. No paid software required. In a hurry? The fastest method that works on any device is a browser-based converter. Convert HEIC to JPG free here — no download, no signup, files auto-delete. The step-by-step OS methods are below if you'd rather use built-in tools.
