What Is a HEIC File (and How Do You Open One)?

If you’ve ever moved photos off an iPhone and found files ending in .heic that won’t open, you’re not alone. Here’s what HEIC is and how to deal with it.

What HEIC actually is

HEIC (High Efficiency Image Container) is the format modern iPhones and iPads use to store photos. It’s based on the HEIF standard and saves images at roughly half the size of a JPG at similar quality, which is why Apple switched to it to save space.

Why it causes trouble

The catch is compatibility. Apple devices handle HEIC natively, but plenty of other places still don’t:

• Older Windows PCs (without an add-on)
• Lots of websites and upload forms
• Some photo editors and older Android phones

So a photo that looks fine on your iPhone can simply refuse to open somewhere else.

The fix: convert to JPG or PNG

The simplest answer is to convert HEIC to a format everything understands:

• HEIC to JPG is best for photos you want to share or upload. Small files, opens everywhere.
• HEIC to PNG is the one to pick if you need a lossless copy or transparency.

Both run entirely in your browser, so your photos are never uploaded. You can convert several at once and download them together.

Tip: stop HEIC at the source

If you’d rather your iPhone just save JPGs, go to Settings, then Camera, then Formats and choose Most Compatible. New photos will be JPG, though you’ll still need to convert the HEIC ones you already have.
