HEIC is a common photo format associated with modern iPhones. It can save space while retaining high image quality, but some Windows applications or websites may expect JPG files.
You can convert a copy of the photo rather than replacing the original.
First check whether Windows already supports HEIC
Try opening the HEIC file in the Windows Photos app.
Depending on your Windows installation and available components, the file may open normally or Windows may indicate that additional support is required.
Use a trusted conversion method
If you need JPG files for a website, older application, or device, use a reputable image converter or a trusted desktop application.
For private photos, an offline tool is preferable to uploading personal images to an unknown website.
Convert copies, not originals
Keep the original HEIC files.
Create JPG versions for compatibility. This preserves the original file if you later need the full-quality source or metadata.
Convert multiple photos in batches
If you have a large photo collection, use software that supports batch conversion.
Before converting hundreds of images, test a small group and compare quality, file size, orientation, and metadata.
Choose sensible JPG quality
Very aggressive JPG compression can create visible artifacts.
For normal sharing, a moderate-to-high quality setting is often a better balance between file size and appearance.
Remember that JPG may be larger
HEIC can be more space-efficient than JPG. Converting a whole library may therefore increase storage usage.
Only convert the photos that actually need JPG compatibility.
Once your photos are in a universal format, it’s a good time to check for duplicates using our guide on finding duplicate photos on your computer. If you haven’t transferred them from your iPhone yet, see how to transfer photos from iPhone to a Windows PC.
Frequently asked questions
Why are iPhone photos HEIC?
