Why Won't My iPhone Photos Open? How to Convert HEIC to JPG Instantly

Introduction

You take a photo on your iPhone. It looks great. You try to upload it to a website, or email it to a Windows computer, and you get an error: “File format not supported.”

Why? Because Apple saves photos as .HEIC (High Efficiency Image Container) by default. While this format saves space on your phone, it is notoriously incompatible with the rest of the web.

You don’t need to change your phone settings. You just need to convert the file.

PicDitt Converter lets you turn HEIC photos into standard JPGs in seconds—right in your browser.

The Problem: The Incompatible File

HEIC is technically superior to JPG—it keeps higher quality at half the file size. That’s why Apple uses it.
But the rest of the world hasn't caught up.

• Windows: Older versions can’t open HEIC natively.
• Websites: Most upload forms (job portals, government sites, forums) reject HEIC.
• Editing Software: Many basic editors only accept JPG or PNG.

If you are seeing a "black screen" or an error message, it’s not your file that’s broken. It’s the format.

Quick Guide: JPG vs PNG vs WebP

Which format should you choose?

• JPG: Best for photos, social media, and printing. (Choose this 90% of the time).
• PNG: Best for screenshots containing text. It keeps lines sharp.
• WebP: Best for website owners who need fast loading speeds.

Privacy: Safe for Family Photos

HEIC files are usually personal photos (family, vacations).
PicDitt converts files in the browser. Your photos are processed locally on your device using WebAssembly technology. They are never uploaded to a cloud server storage.

Conclusion

HEIC is great for storage, but terrible for sharing. The fastest way to fix "File Not Supported" errors is to convert your iPhone photos to JPG.
