The Complete Guide to Converting HEIC Photos to JPEG
You took what looked like a perfect photo on your iPhone. You transferred it to your Windows computer to edit or share it. And then your computer just stared back at you with a blank icon and a message saying it did not know what to do with this file.
Or maybe you sent it to a friend on Android, and they messaged back saying the photo would not open.
You are not doing anything wrong. The file is not corrupted. The problem is a format called HEIC — Apple's default photo format — and the fact that it is not supported by most non-Apple devices and platforms. This guide will explain exactly what HEIC is, why Apple uses it, and most importantly, how to convert your photos to JPEG so they work everywhere.
What Is HEIC and Why Does Apple Use It?
HEIC stands for High Efficiency Image Container. Apple introduced it as the default photo format for iPhone with iOS 11 in 2017. The motivation was storage efficiency: HEIC files are roughly half the size of equivalent JPEG files while maintaining the same or better visual quality.
For iPhone users with limited storage, this is genuinely valuable. Instead of a photo taking 4MB in JPEG format, the same photo might be 2MB in HEIC format, with no visible quality difference. Over thousands of photos, this saves meaningful amounts of storage space.
The technology behind HEIC is genuinely impressive. It uses HEVC (High Efficiency Video Coding) compression, which is far more sophisticated than the decades-old compression technology used by JPEG. Apple was not wrong to adopt it. The problem is that the rest of the world has been slow to follow.
Why HEIC Does Not Work on Most Devices
HEIC is relatively new and uses technology that requires licensing to implement. Microsoft added native HEIC support to Windows 10 and 11, but it requires a free codec download from the Microsoft Store — something most users do not know about and have not done. Most Windows photo viewers and editors do not support HEIC without this codec.
Android phones do not support HEIC natively. Most websites do not accept HEIC uploads. Most photo editing software, including older versions of Photoshop, does not support it. Social media platforms convert HEIC files automatically, but the results are not always optimal.
In practice, HEIC photos live happily on Apple devices but create friction almost everywhere else.
Your Three Options for Dealing with HEIC Photos
Option 1: Convert HEIC to JPEG Using an Online Converter (Easiest)
The simplest approach for converting one or several HEIC photos is an online image converter. The process is:
1. Go to an online image converter website
2. Upload your HEIC file or files
3. Select JPEG (or JPG) as the output format
4. Click convert
5. Download your JPEG files
This takes about thirty seconds per image and works on any device — Windows, Mac, Android, or even another iPhone. No software installation required, no technical knowledge needed.
Option 2: Change iPhone Settings to Shoot in JPEG Directly
If you regularly run into HEIC compatibility issues, the most permanent solution is to configure your iPhone to take photos in JPEG format from the start. This uses slightly more storage, but eliminates the need to convert photos after the fact.
6. Open the Settings app on your iPhone
7. Tap 'Camera.'
8. Tap 'Format.s.'
9. Select 'Most Compatible' instead of 'High Efficiency.cy.'
From this point forward, your iPhone will save photos in JPEG format. Photos you have already taken in HEIC will remain in that format — this setting only affects new photos.
Option 3: Enable HEIC Support on Windows
If you frequently work with HEIC files on a Windows computer and want to view and edit them directly without converting:
10. Open the Microsoft Store on your Windows computer
11. Search for 'HEIF Image Extensions.ons.'
12. Install the free extension
After installation, Windows will be able to open and view HEIC files natively. However, many third-party applications will still not support the format, so conversion is still often necessary for sharing or uploading.
What About Image Quality During Conversion?
This is a common concern, and it is worth addressing directly. When you convert a HEIC photo to JPEG using a quality online converter, the visual quality loss is negligible to the human eye under normal viewing conditions. Both formats are designed to produce visually excellent results, and a HEIC-to-JPEG conversion at a reasonable quality setting (80% or above) will produce a file that looks identical to the original HEIC on screen.
The file size will increase slightly after conversion — JPEG does not achieve quite the same compression efficiency as HEIC. But the visual quality will be excellent.
Frequently Asked Questions
Can I convert multiple HEIC files at once? Yes — many online converters support batch conversion, allowing you to upload multiple HEIC files and download them all as JPEGs at once.
Will my converted JPEG look exactly like the original? For practical purposes, yes. The quality difference is imperceptible under normal viewing conditions.
Should I delete the original HEIC files after converting? Keep the originals until you have confirmed that the conversions look correct and you have backed them up. HEIC has marginally better quality, so the originals are technically superior.
Can I convert HEIC to WEBP instead of JPEG? Yes — WEBP is an excellent choice for photos that will be used on websites, as it provides very similar quality to HEIC at a compatible file format.
