HEIC to JPG Converter

Why your iPhone photos will not open

Since iOS 11, Apple devices have saved photos as HEIC by default rather than JPG. HEIC is a container built on the HEIF standard, and it stores an image compressed with HEVC, the same technology behind modern video. The benefit is real: a HEIC photo is typically around half the size of an equivalent JPG at similar visual quality, which matters a great deal when a phone holds thousands of pictures.

The drawback appears the moment a photo leaves the Apple ecosystem. Windows needs an extension from the Microsoft Store to preview HEIC. Many websites reject the format at upload. Older editors, print services, government portals, and plenty of Android apps simply do not recognise it. You end up with a photo that looks fine on your phone and is useless everywhere else.

What this converter does

Browsers do not ship with a HEIC decoder, which is why dragging one into a normal image tool usually fails. This page loads a decoder on demand the first time you convert, then decodes the photo and re-encodes it as JPG, PNG, or WebP using your device's own processing power.

Because the decoding happens locally, the photo is never sent to a server. That is worth more than convenience here: HEIC files come straight from a phone camera and typically carry GPS coordinates and timestamps, so uploading one to an unknown converter hands over rather more than the picture.

Which output format to choose

JPG is the right answer for almost everyone. It is accepted universally, keeps file sizes reasonable, and is what any form or printer expects. Choose it unless you have a specific reason not to.

PNG is worth choosing when you intend to edit the photo afterwards and want no additional lossy compression, though the file will be substantially larger than the HEIC you started with. WebP is a good choice when the destination is a modern website, since it will usually produce the smallest file of the three while keeping quality high.

Quality and file size

HEIC is already a lossy format, so converting to JPG or WebP applies a second round of lossy compression. This sounds worse than it is: at 85% quality the difference is not visible under normal viewing, and that is why it is the default here. Drop to 70% if you need a noticeably smaller file and can accept some softening in fine texture.

Expect the JPG to be larger than the HEIC, often by fifty percent or more, because JPG is a less efficient format. That is the price of compatibility. If the resulting file is too large for an upload limit, run it through the Image Compressor or one of the fixed-size tools afterwards rather than pushing quality very low here.

Stopping your phone from creating HEIC

If you convert HEIC files regularly, it is easier to change the setting than to keep converting. On an iPhone or iPad, open Settings, tap Camera, tap Formats, and select Most Compatible. From that point new photos are captured as JPG.

Two caveats. Photos already in your library stay HEIC, so you will still need to convert older pictures. And you give up the storage saving, which is meaningful if your device is nearly full. A reasonable compromise is to leave the phone on High Efficiency and convert only the photos you are about to share.

1. Open Settings on your iPhone or iPad.
2. Tap Camera, then tap Formats.
3. Select Most Compatible to capture JPG instead of HEIC.
4. To keep HEIC but share JPG, leave High Efficiency selected and convert individual photos here.

If a photo will not convert

Occasionally a file fails. The most common causes are a Live Photo or burst where the container holds multiple images, a depth or portrait capture with unusual auxiliary layers, or a file that was partially copied and is truncated. A photo transferred over a messaging app may also have been altered in transit.

The most reliable workaround is to open the photo on the Apple device, export or share it as a copy, and convert that copy. Copying files directly from an iPhone over USB sometimes produces partial transfers, so sharing through AirDrop or a cloud folder often yields a cleaner file.
