HEIC vs JPG: What’s the Difference and Which Should You Use?
If your iPhone photos save as .heic and you are not sure whether that is a good thing, you are in the right place. I have spent a lot of time converting, opening, and comparing these two formats across phones, Windows PCs, and editing apps, and the short version is this: HEIC is the technically superior format, but JPG is the one that works everywhere. Which one you should actually use depends entirely on what you plan to do with the photo. Below I break down the real differences, with the trade-offs that matter in daily life rather than spec-sheet trivia.
The quick answer
HEIC (High Efficiency Image Container) is Apple’s implementation of the HEIF standard, built on the HEVC/H.265 codec. JPG (also written JPEG) is a 1992-era format that virtually every device, browser, printer, and app on earth understands.
- Keep HEIC when you are staying inside the Apple ecosystem and want the best quality at the smallest size.
- Convert to JPG when you need to share, upload, print, or edit somewhere that does not speak HEIC, which is still most of the world in 2026.
If you just need files that open anywhere, the fastest route is to convert HEIC to JPG right in your browser. Now let’s look at why.
File size: HEIC wins, often by half
This is HEIC’s headline advantage. Because it uses modern HEVC compression, a HEIC file is typically 40-50% smaller than the equivalent JPG at the same visual quality. In my own tests with iPhone shots, a photo that lands around 3.5 MB as a JPG is often 1.7-2 MB as HEIC with no visible loss.
That difference adds up fast. On a phone with thousands of photos, choosing HEIC can save you several gigabytes of storage and make iCloud backups and AirDrop transfers noticeably quicker. If storage is your main concern, HEIC is the clear winner.
Quality and color depth: HEIC supports 10-bit and HDR
Here is where the gap is biggest, and it is the part most comparisons gloss over.
- JPG is limited to 8-bit color (256 levels per channel, roughly 16.7 million colors). It has served us well for 30 years, but in smooth gradients like a sunset sky you can sometimes see faint “banding.”
- HEIC supports 10-bit color (1,024 levels per channel, over a billion colors) and carries HDR information. This is what lets HDR photos from a modern iPhone look vivid and bright on a compatible display.
So at the same file size, HEIC generally preserves more detail and smoother tones. The catch: that extra color depth only shows on hardware and software that can read it. Send a 10-bit HDR HEIC to an 8-bit context and the benefit collapses, sometimes with washed-out or oddly bright results after conversion if the tone mapping is handled poorly.
HEIC also does things JPG simply cannot: store multiple images in one file (useful for Live Photos, bursts, and depth/portrait data) and use transparency. For a deeper look at what’s inside the container, see my breakdown of what a HEIC file actually is.
Compatibility: JPG wins, and it is not close
This is the reason JPG refuses to die. JPG opens on every operating system, every browser, every email client, every photo kiosk, and every cheap printer made in the last two decades. You never think about whether a JPG will open, because it always does.
HEIC is far more restricted:
- Apple devices (iPhone, iPad, modern Mac): native support.
- Windows 11: support exists but often requires the HEVC codec, and even then some apps refuse it. I wrote a full walkthrough on opening HEIC on Windows 11 because it trips up so many people.
- Older Windows, many Android phones, web uploads, older software: frequently no support at all.
If you have ever emailed a photo to a relative on a PC and they replied “it won’t open,” HEIC was almost certainly the culprit. That single friction point is why I convert before sharing externally.
Editing and uploading
For editing, JPG is the universal currency. Photoshop, GIMP, Lightroom, Canva, and basically every web-based editor accept it without complaint. Many tools now read HEIC too, but plenty still do not, and some that “open” it quietly flatten the 10-bit data.
For web work, JPG is essentially mandatory. Most content platforms, web forms, and older CMS uploaders reject .heic outright. (If your goal is a smaller modern web image rather than maximum compatibility, WebP is worth a look as a middle ground.)

When to keep HEIC vs convert to JPG
After all the testing, my rule of thumb is simple. Match the format to the destination.
Keep HEIC when:
- You are storing photos and want to save space.
- You stay within Apple devices (iPhone to Mac to iPad).
- You are shooting HDR and viewing on a compatible Apple display.
- You want to preserve Live Photos, depth, or portrait data.
Convert to JPG when:
- You are sharing with non-Apple users or unsure what device they have.
- You are uploading to a website, form, marketplace, or older app.
- You are printing at a lab or kiosk.
- You are editing in software that does not fully support HEIC.
- You are archiving photos you want to guarantee will open in 20 years.
A common question I get is whether you should just stop your iPhone from making HEIC in the first place. You can, and I cover the exact setting in my guide on stopping your iPhone from saving HEIC (and why your photos are HEIC by default is explained here). My honest take: leave the camera on HEIC to save storage and quality, then convert copies to JPG only when a specific situation demands it. That gives you the best of both formats.
When you do need JPGs, you do not have to upload your photos to a random server to get them. SnapHEIC converts everything locally in your browser so nothing leaves your device, and it strips EXIF/GPS data on conversion for privacy. If you are curious how that works without uploads, the how it works page lays out the technical details.
Bottom line
HEIC is the better format on paper, smaller files, richer color, HDR, and clever extras. JPG is the better format in practice for anything that leaves the Apple world, because it opens absolutely everywhere. Use HEIC to capture and store, and convert to JPG whenever compatibility matters. With a free browser-based converter, switching takes seconds and you keep both your quality and your privacy.
