You take a photo on your iPhone, transfer it to a Windows PC, and the file has a .heic extension that Windows cannot open. Or you try to upload it to a website and get an error saying the format is not supported. It is one of those small compatibility frustrations that trips up a surprising number of people — because iPhones switched to HEIC as their default photo format several years ago and not everything has caught up.
The fix is straightforward. Here is how to convert HEIC files to JPG on any device, and how to stop your iPhone from saving in HEIC in the first place if you would rather avoid the problem altogether.
What is HEIC and why does iPhone use it?
HEIC stands for High Efficiency Image Container. It is a format developed by Apple (based on the HEIF standard) that stores photos at roughly half the file size of an equivalent JPEG, without any visible drop in quality. A typical iPhone photo in HEIC is around 2 to 3 MB; the same image in JPEG is 4 to 6 MB. For a phone that takes thousands of photos, the storage saving adds up significantly.
The downside is compatibility. HEIC is natively supported on iPhones, iPads, Macs, and recent versions of Android — but not on older Windows versions, most web upload forms, and many third-party apps. JPG, on the other hand, is supported by everything. Converting HEIC to JPG is just bridging that compatibility gap.
How to convert HEIC to JPG online (any device)
The fastest method on any device is to use Filero's free HEIC to JPG converter. It works in any browser — Chrome, Safari, Edge, Firefox — on Windows, Mac, iPhone, or Android. No app to install, no account required.
- Open the HEIC to JPG tool.
- Click Upload HEIC or drag your .heic file onto the page.
- Wait a moment for the conversion to run.
- Click Download JPG.
The output is a standard JPG file that opens in Windows Photos, Preview on Mac, any image editor, and every website that accepts photo uploads. Quality is preserved through the conversion.
How to convert HEIC to JPG on Windows
Windows 10 and 11 can open HEIC files if you install the free HEIF Image Extensions codec from the Microsoft Store. However, this only lets you view HEIC files — it does not give you an easy way to convert them to JPG in bulk or through a simple right-click.
For converting files, the browser-based method above is the quickest. If you need to convert many files at once and want a desktop solution, IrfanView(free) can batch-convert HEIC to JPG: File → Batch Conversion/Rename → select HEIC files → choose JPG as output format.
How to convert HEIC to JPG on Mac
Mac natively supports HEIC, so you may not notice a problem unless you are sharing files with Windows users. To convert to JPG:
- Open the HEIC file in Preview.
- Go to File → Export.
- Change the Format dropdown to JPEG.
- Adjust quality if needed and click Save.
For bulk conversion on Mac, select all the HEIC files in Finder, right-click, and choose Quick Actions → Convert Image. Set the format to JPEG and click Convert to JPEG. This converts all selected files without opening Preview individually.
How to stop iPhone saving photos as HEIC
If you regularly share photos with Windows users or upload to websites, you can switch your iPhone to save photos in JPEG by default. This means slightly larger photo files but zero compatibility issues.
- Open Settings on your iPhone.
- Scroll down and tap Camera.
- Tap Formats.
- Select Most Compatible instead of High Efficiency.
From this point on, the Camera app will save photos as JPEG. Previously taken photos already stored as HEIC are not affected — they will need to be converted individually if needed.
HEIC vs JPG — which is better?
For pure image quality and storage efficiency, HEIC is the better format. It achieves roughly the same visual quality as JPG at half the file size, and it supports a wider colour range. For compatibility and universal sharing, JPG wins — it works everywhere. If you mainly share photos with other iPhone and Mac users, HEIC is fine to keep. If you regularly share with Windows users, upload to websites, or send photos to clients, converting to JPG or switching your camera to Most Compatible mode will save you the hassle.
Frequently asked questions
Does converting HEIC to JPG reduce image quality?
There is a very small quality reduction because JPEG uses lossy compression. In practice, for photo sharing and everyday use, the difference is not visible to the naked eye at normal viewing sizes. If you are printing large-format photos professionally, HEIC (or converting to TIFF/PNG instead of JPG) preserves more data. For everything else, the JPG output from a HEIC conversion looks excellent.
Why does my HEIC file appear as .jpg when I AirDrop it?
Apple automatically converts HEIC photos to JPEG when you share them via AirDrop to a non-Apple device, or when you email them from the Photos app. The conversion happens silently in the background. Where you run into issues is when you transfer files manually — via USB, via cloud storage, or by copying to an SD card — because in those cases the original HEIC file is copied without conversion.
Can I convert multiple HEIC files at once?
On Mac, yes — select multiple files in Finder and use Quick Actions → Convert Image. On iPhone, Filero's tool currently processes one file at a time. On Windows, IrfanView supports batch conversion. If you regularly need to convert large numbers of HEIC files, switching your iPhone to Most Compatible mode (as described above) is the most efficient long-term fix.
Will HEIC files from my iPhone open on Android?
Modern Android devices (Android 9 and later) can typically open HEIC files natively. Older Android phones may not. If you are sharing photos with someone on an older Android device, converting to JPG first is the safest approach to ensure compatibility.
Does the HEIC file include location data? Will JPG keep it?
HEIC files can contain GPS metadata (the location where the photo was taken). When converting to JPG, this metadata is typically preserved in the EXIF data of the output file. If you need to remove location data before sharing a photo — for privacy reasons — use a tool that strips EXIF data, or check the "remove location data" option if available in your conversion tool.
Is HEIC the same as HEIF?
Almost. HEIF (High Efficiency Image File Format) is the standard; HEIC (High Efficiency Image Container) is Apple's specific implementation of that standard. In everyday usage the terms are used interchangeably, and files may have either a .heic or .heif extension. Filero's converter handles both.
