HEIC vs JPEG: Which Format Is Better?

You took a photo on your iPhone, tried to email it, and the recipient said they couldn't open it. Or you downloaded vacation photos to your Windows PC and got hit with "File format not supported." Welcome to the HEIC vs JPEG debate.

HEIC is Apple's default photo format since iOS 11. JPEG has been the universal image standard since 1992. Both store photographs, but they make very different tradeoffs between file size, quality, and compatibility. Here's exactly how they compare and when to use each one.

Quick Comparison Table

What Is HEIC?

HEIC (High Efficiency Image Container) is a file format based on the HEIF standard, using HEVC (H.265) compression to store images. Apple made it the default iPhone camera format in 2017 with iOS 11 because it produces significantly smaller files without visible quality loss.

The format does more than just compress well. A single HEIC file can store image sequences (that's how Live Photos work), depth maps, alpha channels, and non-destructive edits. It's a genuinely modern format that makes JPEG look its age.

What Is JPEG?

JPEG (Joint Photographic Experts Group) has been the default photograph format since before most of the internet existed. Created in 1992, it uses DCT-based lossy compression to shrink photo file sizes to a fraction of the original.

JPEG's superpower isn't technical -- it's ubiquity. Every camera, every phone, every browser, every image editor, every operating system, every social media platform, and every email client supports JPEG. You will never encounter a device that can't open a .jpg or .jpeg file. That 34-year track record of universal compatibility is something no newer format has matched.

File Size and Quality

This is where HEIC pulls ahead decisively. At the same perceived visual quality, HEIC files are roughly 40-50% smaller than their JPEG equivalents. An iPhone photo that would be 4 MB as a JPEG comes out around 2-2.5 MB as HEIC.

The quality advantage goes deeper than just compression efficiency:

• 10-bit color depth. HEIC captures over 1 billion colors compared to JPEG's 16.7 million. You'll notice the difference in smooth gradients -- sunsets, skin tones, and blue skies show visible banding in 8-bit JPEG that looks smooth in 10-bit HEIC.
• Lossless option. HEIC supports lossless compression. JPEG is lossy-only -- every save degrades quality slightly.
• Non-destructive edits. HEIC stores editing instructions separately from the original pixel data. Crop a HEIC photo, and the original is preserved inside the file. JPEG bakes every edit permanently into the pixels.

For pure image quality per byte, HEIC wins. This is why Apple chose it -- iPhones with 128 GB of storage can hold roughly twice as many photos in HEIC as they could in JPEG.

Compatibility and Support

This is where JPEG wins just as decisively. JPEG compatibility is essentially "everything, everywhere":

• Browsers: Chrome, Firefox, Edge, Safari, Opera, and every mobile browser display JPEG natively. HEIC? Only Safari on macOS and iOS. Chrome and Firefox do not support HEIC at all.
• Operating systems: Windows 10/11 can display HEIC after installing a codec extension (free from the Microsoft Store, but not pre-installed). Linux requires libheif. macOS and iOS handle HEIC natively.
• Social media: Instagram, Facebook, Twitter/X, and LinkedIn all accept JPEG uploads directly. Most platforms silently convert HEIC uploads behind the scenes, but some older tools choke on them.
• Email: Send someone a HEIC file and there's a real chance they can't open it. Send JPEG and it works every time.
• Professional tools: Photoshop (v22.0+) and Lightroom support HEIC. Some older or specialized tools do not.

Apple knows this limitation. That's why iPhones automatically convert HEIC to JPEG when you share photos via AirDrop to a non-Apple device, email, or Messages to a non-iMessage contact. But this automatic conversion doesn't always kick in -- which is how you end up with confused recipients staring at .heic files they can't open.

When to Use HEIC

Keep your photos in HEIC when:

• You're staying in the Apple ecosystem. Mac, iPhone, iPad -- HEIC works seamlessly across all of them.
• Storage space matters. Shooting in HEIC roughly doubles your iPhone's effective photo capacity.
• You want maximum quality. The 10-bit color depth and superior compression preserve more detail, especially in photos with gradients and subtle color transitions.
• You're keeping originals. HEIC's non-destructive editing and lossless compression make it a better archival format than JPEG.
• You shoot Live Photos. HEIC is the only format that bundles the image sequence and audio into a single file.

When to Use JPEG

Convert to JPEG (or shoot in JPEG) when:

• You're sharing with non-Apple users. JPEG is the universal language of images. No one has ever said "I can't open this JPEG."
• You're publishing to the web. Browsers don't support HEIC natively (except Safari), so web images need to be JPEG, PNG, or WebP.
• You're uploading to platforms with strict format requirements. Job applications, government forms, e-commerce listings -- many systems only accept JPEG and PNG.
• You're emailing photos. JPEG attachments open inline in every email client.
• You need maximum tool compatibility. Every image editor, from professional suites to free online tools, handles JPEG.

How to Convert Between HEIC and JPEG

When you need to go from HEIC to JPEG (or the reverse), Pixotter's convert tool handles it directly in your browser. No uploading to a server, no installing software -- your images stay on your device.

Here's how:

1. Open Pixotter's HEIC to JPG converter.
2. Drop your HEIC files onto the page (batch conversion works too).
3. Choose your quality setting -- 85% is a good balance of size and quality for sharing, 95% if you want near-lossless output.
4. Download your converted JPEG files.

The conversion runs entirely client-side using WebAssembly, so your photos never leave your browser. This matters if you're converting personal photos and don't want them sitting on someone else's server.

Need a different output format? Pixotter also converts HEIC to PNG for when you need transparency support, or HEIC to WebP for web-optimized output.

FAQ

Is HEIC better quality than JPEG?

Yes, at the same file size. HEIC uses more efficient compression (HEVC) and supports 10-bit color depth compared to JPEG's 8-bit. A 2 MB HEIC file typically looks as good as or better than a 4 MB JPEG. The visual difference is most noticeable in gradients and smooth color transitions.

Why does my iPhone save photos as HEIC instead of JPEG?

Apple made HEIC the default format in iOS 11 (2017) because it produces files roughly half the size of JPEG at the same quality. This effectively doubles your photo storage capacity. You can switch to JPEG in Settings > Camera > Formats > Most Compatible, but you'll use more storage.

Can Windows open HEIC files?

Windows 10 and 11 can open HEIC files after installing the "HEIF Image Extensions" and "HEVC Video Extensions" from the Microsoft Store. The HEIF extension is free; the HEVC extension costs $0.99. Without these, Windows will show HEIC files as unrecognized. Alternatively, convert your HEIC files to JPG for hassle-free viewing on any device.

Should I convert all my HEIC photos to JPEG?

No. Keep your originals in HEIC -- you get better quality in smaller files, and conversion always loses some data. Only convert to JPEG when you need to share with someone or something that doesn't support HEIC. Think of HEIC as your master copy and JPEG as your sharing format.

Is HEIC the same as HEIF?

Not exactly. HEIF (High Efficiency Image Format) is the container standard. HEIC is a specific type of HEIF file that uses HEVC compression. It's like the difference between "video file" and "MP4" -- HEIF is the container, HEIC is the most common implementation. Our HEIC explainer covers this distinction in detail.
