Since iOS 11, iPhones save photos as HEIC (High Efficiency Image Container) to fit more pictures in less space. It is a genuinely excellent format — but Windows, many websites, older Android phones, and plenty of apps still cannot open it. That is the moment you need this converter. It turns your HEIC photos into JPG, the most universally compatible image format on Earth, while keeping the picture looking exactly the way it did on your phone.
Conversion is free, runs online with no app to install, and never adds a watermark. EXIF metadata such as orientation is respected, so portraits stay upright. Drop in one photo or your whole camera roll — batches come back as a single ZIP.
Why won't my iPhone HEIC photos open on Windows or the web?
HEIC is built on the HEVC (H.265) codec, which is patent-encumbered and was slow to gain support outside Apple's ecosystem. Windows needs a paid codec pack, many web upload forms reject the extension outright, and older devices simply do not recognise it. JPG has none of those problems: it has been the lingua franca of digital images for thirty years and opens on literally everything. Converting is the simplest way to make an iPhone photo behave everywhere.
Does converting HEIC to JPG lose quality?
HEIC stores images more efficiently than JPG, so the file gets a little larger when you convert, but at our quality setting of 92 the visible difference is essentially zero. You are trading a small amount of disk space for the ability to actually use the photo. For the everyday job of emailing a picture, printing it, or uploading it to a site, the result is indistinguishable from the original.
How to stop your iPhone making HEIC in the first place
If you would rather not convert every time, you can tell your iPhone to shoot JPG directly: open Settings → Camera → Formats and choose Most Compatible. New photos will be saved as JPG. Existing HEIC photos still need converting, which is where this tool comes in — and many people keep shooting HEIC to save space and just convert the few photos they need to share.
Keep going: PNG, PDF and WebP
JPG is the right answer most of the time, but not always. For a photo you intend to edit or place on a coloured background, HEIC to PNG gives you a lossless file. To turn a batch of photos into a single shareable document, HEIC to PDF binds them into one PDF. And for the web, HEIC to WebP produces the smallest files of all.
