When it comes to digital photos, HEIC and JPG are two of the most important formats you’ll encounter. If you use an iPhone or modern Apple device, your images are likely saved as HEIC. If you share, edit, or upload photos online, you’re probably working with JPG. But what’s the real difference between these formats, and which one should you use?
As the developer of FastConverter.app, I’ve helped thousands of users navigate the world of image formats. This guide breaks down HEIC and JPG, explains their strengths and weaknesses, and helps you choose the right format for your needs.
HEIC (High Efficiency Image Container) is Apple’s default photo format since iOS 11. It uses advanced compression to store high-quality images in smaller files. HEIC supports features like transparency, 16-bit color, and can hold multiple images (such as Live Photos) in a single file. The main advantage: you get great quality and save storage space.
JPG (or JPEG) is the world’s most widely supported image format. It’s been the standard for decades, and nearly every device, app, and website can open JPG files. JPG uses lossy compression, which means some image data is discarded to reduce file size. It’s perfect for sharing, uploading, and editing photos anywhere.
| Feature | HEIC | JPG |
|---|---|---|
| File Size | Smaller files for the same quality | Larger files, but universally supported |
| Image Quality | Supports 16-bit color, transparency, multiple images | 8-bit color, no transparency, single image per file |
| Compatibility | Apple devices, some newer Windows/Android versions | All devices, apps, and websites |
| Features | Live Photos, animations, advanced metadata | Simple, reliable, easy to use |
HEIC is ideal for saving space on your iPhone or iPad, storing high-quality images, and using advanced features like Live Photos. If you’re staying within the Apple ecosystem, HEIC is a smart choice.
JPG is best for sharing, uploading, and editing photos on any device or platform. If you need maximum compatibility, JPG is the way to go. Many websites, apps, and services only accept JPG files.
If you need to convert HEIC to JPG, use the HEIC to JPG Converter on FastConverter.app. This free online tool lets you instantly convert HEIC images from your iPhone, iPad, or computer to the universally compatible JPG format. All processing happens securely in your browser—your files are never uploaded, and you can batch convert up to 8 images at a time.

HEIC offers better compression and quality, but JPG wins for universal compatibility. For Apple users, HEIC is great for personal storage. For sharing, editing, and publishing, JPG remains the gold standard. Use FastConverter.app to switch formats whenever you need.
