Why your iPhone saves photos as HEIC
Since iOS 11, iPhones save photos in HEIC (High Efficiency Image Container) format by default. HEIC keeps the same quality as JPG in roughly half the space, which is great on the phone — but the moment a photo leaves the Apple ecosystem, trouble starts: Windows PCs, Android phones, older photo editors, printers and most website upload forms can't open .heic files at all. Converting to JPG fixes that in one step, because JPG is the one photo format every device and app on earth understands. This converter does the decoding right in your browser with an open-source HEIC decoder — your photos are converted on your own device and never sent to a server, which matters when the photos are personal.
Questions
What is a HEIC file?
HEIC is the photo format Apple uses on iPhone and iPad (the file extension is .heic or .heif). It stores high-quality photos in about half the space of JPG, but support outside Apple devices is patchy — which is why a photo that looks fine on your phone may show up as an unopenable file on a PC.
Why won't my iPhone photos open on my Windows PC or Android phone?
Windows and Android don't include a HEIC decoder by default, and many apps and websites simply don't support the format. The photo itself is not damaged — the device just can't read it. Converting it to JPG (or PNG) with this tool gives you a copy that opens everywhere, while your original HEIC file stays untouched.
Does converting HEIC to JPG lose quality?
JPG is a lossy format, so a small amount of data is discarded — but at the default quality of 92 the result is visually indistinguishable from the original for viewing, sharing and printing at normal sizes. If you need a mathematically lossless copy instead, choose PNG above; just expect files two to five times larger than the JPG.
