HEIC vs JPG: What is the Difference?

What Is HEIC?

HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It uses modern HEIF compression technology, and it became the standard because it does one thing very well: it stores high-quality images in a much smaller file size than JPG.

What Is JPG?

JPG (or JPEG) has been the universal standard for digital photos since the 1990s. It's supported by virtually every device, browser, website, and piece of software ever made. That universal support is JPG's biggest strength - and the main reason it's still the default expectation almost everywhere outside Apple's own ecosystem.

Visual comparison

The photo at the top of this page is a real shot from Scotland, saved as both HEIC and JPG. At normal viewing size the difference is hard to spot - but the file sizes tell a different story.

The HEIC original is roughly half the size of the JPG export at similar visible quality. Differences are most noticeable when zooming in or printing large.

HEIC vs JPG: Quality

At the same file size, HEIC images generally retain noticeably more detail and fewer compression artifacts than JPG. Apple's compression algorithm is simply newer and more efficient. If you're comparing two photos of identical quality rather than identical file size, HEIC will almost always take up less storage space to achieve the same result.

In practice, most people can't tell the difference at normal viewing sizes - the gap shows up mainly in large prints, heavy zooming, or professional editing work.

HEIC vs JPG: File Size

This is where HEIC clearly wins. HEIC files are typically 40-50% smaller than an equivalent-quality JPG. That's a meaningful difference if you're low on phone storage or backing up thousands of photos - which is exactly why Apple made it the default in the first place.

HEIC vs JPG: Compatibility

This is where JPG wins decisively:

• Windows: Native HEIC support is limited or absent depending on your Windows version, often requiring an extra codec install
• Websites and web forms:Most upload fields, e-commerce platforms, and content management systems don't accept HEIC at all
• Older software: Photo editors, printing software, and design tools frequently only recognize JPG
• Cross-platform sharing: Android devices, many cloud services, and non-Apple apps can struggle to open HEIC properly

JPG, by contrast, works everywhere, on everything, with zero setup.

So Which Should You Use?

The practical rule most people land on: let your iPhone keep shooting in HEIC to save storage, and convert to JPG only when you need to share, upload, or use the photo somewhere that doesn't fully support HEIC.

How to Convert HEIC to JPG

If you've got HEIC photos that need to become JPGs, you have a few options:

• On iPhone:Go to Settings → Camera → Formats → select "Most Compatible" - this only affects photos taken going forward, not your existing library
• On Mac: Open the photo in Preview, then File → Export, and choose JPEG
• On Windows or without installing anything: Use a free browser-based converter like Crest Convert's HEIC to JPG tool - just drag and drop your files, and it converts them directly in your browser without uploading anything to a server

Prefer a lossless copy or need transparency? You can also convert HEIC to PNG instead - same drag-and-drop process, entirely in your browser.

Bottom Line

HEIC isn't a mistake or a bug - it's a genuinely better format for storage efficiency, which is why Apple defaults to it. The friction only comes from the rest of the world not fully catching up yet. Until it does, keeping a fast, free HEIC-to-JPG converter on hand is the simplest way to get the best of both: Apple's storage savings, and everyone else's compatibility.
