If you moved iPhone photos to a Windows PC and they will not open, or a website rejected your .heic upload, the fix is to convert them to JPG or PNG. You can do it in your browser in a few seconds, for a single photo or a whole camera roll, without installing anything or uploading your pictures.
The quick answer
Open the HEIC to JPG converter, drop your .heic files in, choose JPG or PNG, and download. Everything happens on your device, so your photos never leave your computer.
Why iPhone photos are HEIC in the first place
HEIC is Apple’s version of the HEIF format. iPhones have saved photos this way by default since iOS 11 because it packs the same quality into about half the storage of a JPG. That is great on your phone and awkward everywhere else: Windows, older apps, and many upload forms still expect JPG or PNG, so a .heic file shows up as a blank icon or gets rejected.
Converting to JPG solves it because JPG opens on every device, in every browser, and in every photo app.
Convert HEIC to JPG or PNG
- Open the converter.
- Drop in your
.heicor.heiffiles. You can add a whole batch at once. - Choose JPG for small, shareable files, or PNG if you want lossless quality and transparency.
- For JPG, set the quality. Around 85 keeps photos looking identical to the original at a much smaller size.
- Download a single image, or grab the whole batch as a zip.
The conversion runs in your browser tab, so there is no upload wait, no account, and no copy of your photos kept anywhere.
JPG or PNG: which should you pick?
Choose JPG for normal photos you want to share, email, or upload. The files are small and the quality is excellent.
Choose PNG when you need lossless quality or transparency, for example a screenshot or a graphic you plan to edit. PNG files are larger, so they are not the best choice for a full camera roll.
Opening HEIC on Windows without converting
If you would rather view HEIC files in the Windows Photos app, install Microsoft’s free HEIF Image Extensions from the Microsoft Store. That lets you see them, but it does not change the format, so any site that rejects .heic will still reject them. To actually use the photos elsewhere, converting to JPG is the reliable option.
Convert a whole camera roll at once
Transferring a batch of photos from an iPhone usually leaves you with dozens of .heic files. Drop them all into the converter together, pick your format once, and download the lot as a zip. There is no per-file limit and nothing is uploaded, so even a large transfer stays private and quick.
Once your images are JPG, you can compress them to shrink the files further, or convert to WebP or AVIF for the smallest possible size on the web.
