How to Convert HEIC to JPG (iPhone Photos Explained)

You just took a photo on your iPhone, tried to upload it somewhere, and got an error. The culprit is almost always HEIC — Apple's default photo format since iOS 11. It's efficient and high quality, but the rest of the world hasn't caught up. Most websites, Windows PCs, and Android devices still expect JPG.

What is HEIC?

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard. It stores photos at roughly half the file size of an equivalent JPG, with no visible quality loss. That's why Apple switched to it — your iPhone's storage goes further without sacrificing image quality.

The problem is compatibility. While macOS and iOS open HEIC natively, Windows needs a paid codec, most Android devices can't read it, and the majority of photo-editing and upload tools only accept JPG or PNG.

When you need to convert

• Uploading a photo to a website or form that rejects HEIC.
• Sending a photo to someone on Windows or Android.
• Using an older photo editor that doesn't recognise the format.
• Posting to a platform that strips HEIC files silently.

What happens during conversion

Converting HEIC to JPG re-encodes the image using JPG's compression. At 85–90% quality the result looks identical to the original. The file will typically be slightly larger than the HEIC version — that's normal, not a sign something went wrong.

One thing to be aware of: JPG doesn't support transparency. If your HEIC image has a transparent background (rare for camera photos, more common for edited images), that transparency will become white in the JPG output.

Tips for the best result

• Convert at 90% quality to keep the image sharp for printing or editing.
• Use 80% for web uploads — still looks great and loads faster.
• If you're converting a batch of photos, check a few after to make sure the quality looks right.
• Keep your original HEIC files if storage allows — they're smaller and better quality as an archive.

A browser-based converter handles the whole process on your device — your photos never get uploaded to a server, which matters when they're personal. The conversion takes a couple of seconds per photo and produces a JPG that works everywhere.
