How to Convert HEIC Files to JPG

Why iPhone's default format won't open in most places, and the practical fix.

Summary

iPhones save photos in HEIC format by default. It takes up less space, but it may not open cleanly on Windows, on some websites, or on older devices. The fix is to convert the file to the widely supported JPG format before sharing it.

Step by step

First transfer the photo from your iPhone's Files app or gallery to your computer.
Upload the file to a browser-based HEIC-to-JPG tool; it's fast and safe since the file never leaves your device.
Check the quality after conversion, and avoid changing the resolution unless you need to.
Share the resulting JPG anywhere — email, a website, or social media — without compatibility issues.

Why it matters

The HEIC problem tends to appear at the worst moment. An application form rejects your photo as an unsupported file type, or the person you sent it to can't open it on their PC. Converting to JPG before sharing avoids the back-and-forth and spares the other person from installing anything.

Fixing it at the source

If you often share photos with non-Apple devices, two iPhone settings can save you effort:

Settings > Camera > Formats > "Most Compatible" makes new photos save as JPG. The trade-off is that they take more space on your phone.
Settings > Photos > "Transfer to Mac or PC" set to "Automatic" converts photos to a compatible format when you copy them to a computer over a cable.
Neither setting touches HEIC photos you've already taken. Those still need converting.

Common mistakes

Renaming the file from .heic to .jpg. That changes the name, not the contents, and most programs still won't open it.
Taking a screenshot of the photo to dodge the format issue. You lose resolution and may capture bits of the screen around it.
Sharing without thinking about location data. Whether a converted file keeps the original metadata depends on the tool, so check if location matters to you.
Forgetting that a Live Photo becomes a single still frame after conversion.

A worked scenario

A student applying for a scholarship needs to upload an ID photo and a picture of her transcript. The application site accepts only JPG and PDF, and her iPhone photos are HEIC. She copies both to her laptop and converts them with a browser-based tool, leaving the resolution alone so the small print on the transcript stays readable. Before uploading, she opens the JPGs to make sure the text is sharp, and the application goes through without trouble.

When to leave HEIC as it is

If the photos will only live on your Apple devices and in iCloud, there's no reason to convert. HEIC keeps the same quality in less space. Converting at the moment you share keeps your library smaller.
