HEIC vs JPEG: What's the Difference?
HEIC and JPEG are both photo formats, but they're built on fundamentally different compression technologies. HEIC (Apple's default since 2017) uses video-era compression to produce smaller files at higher quality. JPEG uses a 1992 compression standard that every device on earth understands. Which one is better depends entirely on what you're doing with the photo.
File Size: The Clearest Difference
The most measurable difference between HEIC and JPEG is file size. HEIC consistently produces files that are 40–50% smaller than JPEG at equivalent visual quality.
Here's what typical iPhone 15 Pro photos look like when saved in each format at similar quality:
| Photo Type |
HEIC Size |
JPEG (High Quality) |
Difference |
| Outdoor daylight photo (12MP) |
3.1 MB |
5.8 MB |
HEIC 47% smaller |
| Indoor portrait (low light) |
2.4 MB |
4.2 MB |
HEIC 43% smaller |
| Landscape with fine detail |
4.1 MB |
7.6 MB |
HEIC 46% smaller |
| Screenshot (text and UI) |
0.8 MB |
0.9 MB |
Similar |
For someone with 5,000 photos on their iPhone, this difference adds up to roughly 15–20 GB of storage saved by using HEIC instead of JPEG. That's why Apple made the switch.
Image Quality: Visible Differences
At normal viewing sizes — phone screens, laptop displays, social media — HEIC and JPEG look identical to most people. The differences emerge in specific situations:
Gradient and Sky Photos
HEIC supports 10-bit color (over 1 billion colors). JPEG maxes out at 8-bit (16.7 million colors). The practical effect: JPEG can show visible banding in smooth gradients — blue skies, sunset color transitions, and shadow areas. HEIC renders these more smoothly. If you've ever noticed a stepped look in a blue sky photo, that's JPEG's 8-bit ceiling.
Compression Artifacts
JPEG compression produces characteristic blocky artifacts at high compression ratios, most visible in areas of flat color and sharp edges (like text on a photo). HEIC uses a more sophisticated algorithm that handles these areas better. At equivalent file sizes, HEIC photos generally look cleaner.
Zoomed-In Detail
At 100% zoom on a high-resolution monitor, HEIC tends to preserve fine detail — hair, fabric texture, foliage — more accurately than JPEG at the same file size. For casual viewing and sharing, this doesn't matter. For printing large format or professional editing, it can.
Where the Difference Disappears
For social media uploads, thumbnails, and anything displayed at less than full resolution, HEIC and JPEG are practically identical. Instagram, Facebook, and most platforms re-compress photos on upload anyway, eliminating any format advantage.
Compatibility: Where JPEG Wins Decisively
JPEG was standardized in 1992 and is supported by essentially every digital device, software application, and online service ever made. HEIC was introduced in 2017 and is still catching up.

Which Format Should You Use?
The practical answer is: keep shooting HEIC on your iPhone, convert to JPEG when you need to share or use photos outside the Apple ecosystem.
HEIC gives you better quality in half the space. Over time, the storage savings are meaningful, and the quality advantages matter for photos you care about.
The compatibility problem is real but solvable. For any specific file that needs to work on a PC, upload to a website, or go into a document, converting to JPEG takes about 10 seconds.
Switching your iPhone to JPEG permanently doubles your photo storage consumption. Unless you're constantly transferring photos to Windows and find conversion annoying, the math doesn't favor JPEG.
Special Cases Where JPEG Makes More Sense
- You use Windows primarily and transfer photos daily: Install the free HEIF Image Extensions codec from the Microsoft Store and stay on HEIC, or switch your iPhone to JPEG. Both work; the codec install is faster and preserves storage efficiency.
- You're a photographer sharing with clients on diverse systems: Deliver in JPEG. Your clients will be on Windows, Android, and various software versions. JPEG is the universal delivery format even if you shoot in a higher-quality format internally.
- You submit a lot of forms online: Many web services still reject HEIC. Convert individual photos to JPEG as needed using HEICtoJPG.com.
- You print photos professionally: Ask your print lab. Most modern labs accept HEIC, but some older workflows require JPEG or TIFF. Confirm before submitting a large order.
Is HEIC the Future?
HEIC is gaining ground but hasn't achieved JPEG's universal support. There's also a newer format — AVIF — that improves on HEIC the same way HEIC improved on JPEG, and it has the advantage of being royalty-free (HEVC, which powers HEIC, carries licensing fees that slowed adoption).
For most iPhone users in 2025, the practical picture is: HEIC on device, JPEG for sharing. The gap in compatibility has narrowed significantly over the past few years and will continue to narrow. JPEG isn't going away — it's simply too entrenched — but HEIC has secured its place as the preferred format within the Apple ecosystem.
