HEIC has been around for several years and is widely used on Apple devices.
Despite that, many websites and web applications still don’t accept HEIC uploads — which often surprises users.
From a web development perspective, this isn’t just inertia. There are practical reasons behind it.
HEIC Support Isn’t as Universal as It Seems
While HEIC works well on iOS and macOS, support drops off quickly outside that ecosystem.
Common limitations include:
- Browsers that can’t decode HEIC natively
- Backend image pipelines built around JPG and PNG
- Third-party libraries lacking stable HEIC support
For many web platforms, supporting HEIC adds complexity without clear benefits.
Server-Side Image Processing Constraints
Most upload systems rely on established image processing tools.
Many of these tools were designed long before HEIC became popular.
Typical issues include:
- Missing or unstable HEIC decoders
- Increased processing cost
- Additional security considerations
As a result, many platforms simply restrict uploads to more predictable formats.
User Experience Trade-Offs
From a UX perspective, rejecting HEIC uploads isn’t ideal — but neither is inconsistent rendering.
Websites need to ensure that:
- Uploaded images display correctly for all users
- Thumbnails and previews are reliable
- Images can be resized and optimized consistently
Until HEIC support becomes more uniform, JPG and PNG remain safer choices.
How People Usually Work Around This
In practice, users often deal with HEIC limitations by:
- Changing camera settings to shoot JPG
- Letting cloud services auto-convert files
- Manually converting HEIC images before uploading
The last option tends to be the most flexible, especially when dealing with multiple platforms.
A Lightweight Conversion Option
After running into upload issues repeatedly, I ended up using a small HEIC to PNG converter for quick compatibility fixes.
If you need to upload HEIC photos to websites that don’t support them, converting them to PNG first usually avoids most problems:

It’s a simple, browser-based solution meant for quick conversions rather than complex workflows.
Final Thoughts
HEIC is technically efficient, but web compatibility still hasn’t caught up.
Until broader support becomes standard, converting HEIC files remains a practical necessity for many users and developers.
Understanding these limitations helps explain why HEIC uploads are still restricted across much of the web.
