What is HEIC and How to Convert iPhone Photos to JPG?

If you are an iPhone user and have ever transferred your fantastic photos to a Windows computer or tried to upload them to an official website only to receive an "Invalid Format" error, the culprit is the HEIC format. So why does Apple use this format, and how can we easily solve this problem?

What is HEIC? Why Won't it Open?

HEIC (High-Efficiency Image Container) is a highly efficient image format developed by Apple to save storage space. It offers much higher visual quality than the traditional JPG format while taking up half the space.

Although it is a brilliant technology, its biggest flaw is compatibility. Many older Windows PCs, Android devices, or official government and visa application websites do not recognize or open the HEIC format.

Step-by-Step Conversion:

2. Local Decoding: Your browser will instantly begin the "Decoding" process without ever sending the photo to the internet.
3. Select Format: Once decoded, select the universally compatible "JPG / JPEG" format from the dropdown menu.
4. Download: Click the "Convert and Download" button to safely save your photo so it can be opened on any Windows device.

Important Tips

• Do Not Choose PNG: Converting real-life photographs taken with a camera to PNG will result in massively inflated file sizes. Always prefer JPG for photographs.
• Batch Processing Limits: Because the process utilizes your computer's RAM, trying to convert 100 HEIC photos simultaneously may freeze your browser. It is always faster and safer to process them in batches of 5 to 10.
