What is HEIC?

HEIC (High-Efficiency Image Container) is the file format Apple uses to store images on its newer iPhones and Macs. It's based on the HEVC (High-Efficiency Video Coding) video format. The main advantage is its superior compression, allowing you to store high-quality photos in roughly half the space of a JPG.

Apple introduced HEIC with iOS 11 in 2017 as the default photo format for iPhones. It uses advanced compression algorithms that are significantly more efficient than JPEG while maintaining similar or better visual quality. HEIC supports multiple images in a single file (like Live Photos), transparency (alpha channel), and can store depth maps and other metadata that traditional formats cannot.

What is JPG?

JPG (or JPEG) has been the standard for digital photos since the 90s. Its "lossy" compression algorithm smartly discards some image data to reduce file size, which is why it became so popular for web pages and digital cameras. It is, without a doubt, the most universally recognized and supported image format in the world.

JPEG (Joint Photographic Experts Group) was standardized in 1992 and quickly became the dominant format for digital photography. Its success is due to its excellent balance between file size and quality, making it ideal for storage and transmission. Almost every device, application, and website in the world can open and display JPEG files without any special software or codecs.

Technical Deep Dive

Compression Algorithms

HEIC

HEIC uses HEVC (H.265) compression, a modern codec that's significantly more efficient than older standards. It can achieve similar quality at roughly half the file size of JPEG by using advanced prediction algorithms and better color space handling.

JPG

JPEG uses the older DCT (Discrete Cosine Transform) compression from the 1990s. While effective, it's less efficient than modern codecs. Each time you save a JPEG, it re-compresses, which can lead to quality degradation over multiple saves.

Color Space Support

HEIC

HEIC supports wider color gamuts including Display P3 and can store images in 10-bit or 16-bit color depth, providing smoother gradients and more accurate color representation, especially for HDR photos.

JPG

JPEG is typically limited to 8-bit color depth with sRGB color space, which is sufficient for most uses but lacks the color fidelity of modern formats for professional photography or HDR content.

Metadata and Extensions

HEIC

HEIC can store extensive metadata including depth maps, alpha channels, multiple images, and even video sequences (Live Photos). This makes it more versatile for advanced photography features.

JPG

JPEG supports EXIF metadata (camera settings, GPS, etc.) but is limited to a single image per file and doesn't support transparency or depth information.

When to Use Each Format

Best Use Cases for HEIC

• Storing photos on iPhone or iPad to save storage space
• Professional photography workflow on Apple devices
• When you need transparency support in a single file format
• HDR photos that benefit from wider color gamuts
• Archiving photos where file size matters more than compatibility

Best Use Cases for JPG

• Sharing photos via email or messaging apps
• Uploading to websites, social media, or cloud storage
• When compatibility with older devices or software is required
• Professional printing services that require JPEG
• Web content where file size and universal support are critical

Conversion Recommendations

If you're working primarily within the Apple ecosystem (iPhone, Mac, iPad), keeping photos in HEIC format maximizes storage efficiency. Apple devices handle HEIC natively, so you benefit from smaller file sizes without any drawbacks.

However, if you frequently share photos with Windows users, upload to websites, or use non-Apple devices, converting to JPG is recommended. Modern conversion tools can convert HEIC to JPG with minimal quality loss, preserving most of the visual fidelity while ensuring universal compatibility.

For professional photographers, consider keeping originals in HEIC (or RAW) format for editing and archival purposes, then exporting to JPG for sharing and distribution. This workflow gives you the best of both worlds: storage efficiency and broad compatibility.

The Verdict: Which is Better?

There's no single "best" format—it depends on your needs.

For storing photos on your iPhone: HEIC is superior. You get the same or better quality for half the storage space. Your iPhone handles HEIC natively, so you'll never notice a difference in quality or functionality.

For sharing photos with others or posting online: JPG is the safer bet. You never have to worry if the recipient can open the file. Virtually every device, application, and website supports JPG, making it the universal standard for photo sharing.

For a hybrid approach: Use HEIC for storage on your Apple devices, and convert to JPG when sharing. This gives you storage benefits at home and compatibility benefits when sharing. Online converters make this conversion quick and easy.

That's why tools like ours are so useful. You can enjoy the storage benefits of HEIC on your device, and when you need to share, you can quickly convert your HEIC files to JPG for universal compatibility.

Frequently Asked Questions

Does converting HEIC to JPG reduce quality?

Yes, slightly. JPG uses lossy compression, so some quality is lost during conversion. However, when using high-quality conversion settings (90%+), the difference is virtually imperceptible to the human eye. The quality loss is minimal compared to the compatibility benefits you gain.

Can I convert JPG back to HEIC?

Technically yes, but it's not recommended. Converting JPG to HEIC won't recover the original quality that was lost during JPG compression. The file size reduction will be minimal since JPG is already compressed. You're essentially re-compressing an already compressed image, which further degrades quality.

Which format uses less storage space?

HEIC uses significantly less storage space - typically about 50% smaller than JPG at similar quality levels. This is why Apple made it the default format on iPhones, allowing users to store more photos on their devices.

Will HEIC become more widely supported in the future?

Support is gradually increasing. Windows 10/11 can view HEIC files with HEIF Image Extensions, and many modern applications support it. However, JPG will likely remain the universal standard for sharing due to its decades-long dominance and near-universal compatibility.

Should I convert all my HEIC photos to JPG?

Not necessarily. If you primarily use Apple devices and don't frequently share photos, keeping them in HEIC saves storage space. Convert to JPG when you need to share with Windows users, upload to websites, or use non-Apple devices. Many users keep originals in HEIC and convert only when needed.

Can HEIC files contain multiple images like GIFs?

Yes! HEIC can store multiple images in a single file. This is how Apple's Live Photos work - they store both a still image and a short video sequence in one HEIC file. JPEG cannot do this - each image must be a separate file.

Which format is better for printing photos?

Both work well for printing, but JPG is more widely accepted by printing services. Most professional photo printing services prefer JPEG format. If you have HEIC files, converting them to high-quality JPG (95%+) will work perfectly for printing purposes.
