How to Convert HEIC to JPG (iPhone Photos)

What is HEIC?

HEIC (High Efficiency Image Container) is the file format the iPhone and iPad have used by default since iOS 11 in 2017. It stores photos using the HEIF standard with HEVC compression, which fits the same visual quality into roughly half the file size of a JPG. That is great for your phone's storage, but only if the software you send the photo to knows how to read it.

The catch is compatibility. HEIC is an Apple-led format, and support elsewhere has been slow. That is why a photo that looks fine on your iPhone can arrive as an unopenable file on a friend's Windows laptop or refuse to upload to an older website.

Why HEIC files will not open

The problem is almost never a broken file. It is that the app or site you are using does not support the format. Common places HEIC fails: Windows before version 10 (and even then it needs an extension), older versions of Photoshop, many web upload forms, some email clients, and a lot of Android apps. JPG, by contrast, opens everywhere and has for decades.

• You email a photo and the recipient sees a file they cannot preview.
• A job application or government form rejects the upload because it only accepts JPG or PNG.
• A print service or marketplace listing will not accept HEIC.
• You move photos to a Windows PC and Photos shows an error.

How to convert HEIC to JPG

The fastest fix is to convert the file to JPG, which is the universal photo format. You do not need to install anything or send your photos anywhere:

1. Open the HEIC to JPG converter and select one or more HEIC files from your phone or computer.
2. The conversion runs in your browser on your own device, so the photos are never uploaded.
3. Download the JPG version of each file.
4. Use the JPG anywhere: email, upload forms, Windows, print services, or older apps.

Stop your iPhone saving HEIC in the first place

If you would rather avoid converting every time, you can tell your iPhone to capture in the more compatible format. Go to Settings, then Camera, then Formats, and choose Most Compatible instead of High Efficiency. New photos will be saved as JPG. Existing HEIC photos still need converting, and you lose the storage savings, so many people leave the setting on High Efficiency and just convert the few photos they need to share.

Does converting HEIC to JPG lose quality?

Converting from HEIC to JPG is a re-encode, so there is a small, usually invisible quality change, and the JPG file will be larger because JPG is less efficient than HEIC. For sharing, printing, and uploading, the difference is not noticeable. If you plan to edit heavily afterwards, convert to PNG, which is lossless, to avoid stacking compression.

Frequently asked questions

What does HEIC stand for?

HEIC stands for High Efficiency Image Container. It is Apple's implementation of the HEIF image standard, using HEVC (H.265) compression to store photos at about half the size of an equivalent JPG while keeping similar visual quality.

Is HEIC better than JPG?

For storage, yes: HEIC produces smaller files at the same quality and supports extras like depth data and wider color. For compatibility, no: JPG opens on virtually every device, app, and website, while HEIC still fails in many places. Keep HEIC for storage on your phone and convert to JPG when you need to share.

Are my photos uploaded when I convert?

With an in-browser converter, no. The conversion happens on your own device using your browser, so the image data never leaves your computer or phone. You can confirm this by turning off your internet connection after the page loads and converting anyway. Server-based converters do upload your photos, so prefer a local tool for private images.

Can I convert many HEIC files at once?

Yes. Select multiple HEIC files and convert them in one batch, then download the JPGs. This is the quickest way to prepare a full set of iPhone photos for a Windows PC, a print order, or an upload form that only accepts JPG.

Why is my converted JPG bigger than the HEIC?

Because JPG is an older, less efficient format. HEIC packs the same detail into a smaller file, so converting to JPG typically doubles the size. If file size matters, run the JPG through an image compressor afterwards to bring it back down.
