HEIC vs JPG: Which Should You Use in 2026? (And How to Convert)
HEIC vs JPG explained: the real differences in size, quality and compatibility, which to use when, and exactly how to convert HEIC to JPG.
HEIC is Apple's default photo format since 2017: about half the file size of JPG at similar quality, with 10-bit colour and extras like Live Photos and depth. The catch is compatibility, only Safari and Apple devices open it cleanly, so it breaks on most websites and non-Apple software. JPG is older and larger but works everywhere. Keep HEIC on your iPhone to save space, and convert to JPG the moment a photo leaves the Apple world.

Your iPhone is quietly saving photos in a format half your friends cannot open.
That format is HEIC, Apple's default since 2017. On paper it beats JPG easily: smaller files, richer colour, more data packed into every shot.
And it breaks the moment it leaves the Apple world...
So which should you actually use? The short version: keep HEIC on your iPhone, convert to JPG the second a photo needs to go anywhere else. Here is the full picture, and exactly how to convert.
What is a HEIC file?
HEIC is how modern iPhones save photos. It is a HEIF image compressed with HEVC (the H.265 video codec), carrying the .heic extension.
Skip the acronym debates (even "the C" is disputed). What matters is what it does: it squeezes a photo into far less space than JPG while holding more information.
A single HEIC file can carry things a JPG simply cannot:
- Live Photos and short image sequences.
- Depth maps for portrait-mode blur.
- 10-bit colour (about a billion shades).
- Transparency and multiple images in one file.
Apple made it the default capture format in iOS 11 (September 2017), and it has been the standard on iPhones ever since.
What is a JPG (JPEG) file?
JPG is the format the whole internet already agrees on. Standardised back in 1992, it runs on every device, browser, app and printer you will ever touch.
The trade-off is that it is old and simple:
- 8-bit colour (about 16.7 million shades).
- One image per file, no depth, no transparency.
- Larger files than HEIC at the same quality.
It is not exciting. It just works, everywhere, and that is exactly why it refuses to die.
HEIC vs JPG: the key differences
| HEIC | JPG | |
|---|---|---|
| File size | ~Half of JPG (Apple's design goal) | Larger |
| Colour depth | 10-bit (~1 billion) | 8-bit (~16.7 million) |
| Transparency | Yes | No |
| Live Photos / depth | Yes | No |
| Compression | HEVC (H.265) | JPEG |
| Works in all browsers | No (Safari only) | Yes |
| Windows / Android | Needs extensions | Native |
| Best for | Storage on Apple devices | Sharing, web, anything |
The pattern is clear: HEIC wins on the technology, JPG wins on getting along with everyone else.
Is HEIC better than JPG?
Technically? Yes, and it is not close. Smaller files, deeper colour, more data.
Practically? It depends entirely on where the photo is going.
The one-line answer
Choose by destination, not specs. Staying on your iPhone or Mac → HEIC, and enjoy the space savings. Going to Windows, Android, a website, a printer, or a client → JPG, every time.
HEIC vs HEIF: what is the difference?
People use these interchangeably. They are not the same.
- HEIF is the container, an open MPEG/ISO standard for storing images and their metadata.
- HEIC is HEIF with the picture compressed using HEVC. It is the specific flavour Apple ships, with the
.heicextension.
So all HEIC is HEIF. But not all HEIF is HEIC (the container can hold other codecs, like AV1). It is not proprietary Apple tech either, Apple adopted an open standard.
Why does my iPhone save photos as HEIC?
One reason: space.
HEIC stores your photos in roughly half the room JPG needs. Across thousands of photos, that means a phone that fills up slower and iCloud backups that stay smaller. For Apple, on Apple devices, it is the obvious default.
The friction only shows up when those photos leave.
When should you convert HEIC to JPG?
Convert whenever the photo is heading out of the Apple ecosystem:
- Sharing with Windows or Android users.
- Uploading to a website or a form that rejects HEIC.
- Editing in software that cannot read it.
- Sending to a printer or a print service.
- Publishing images on the web.
Inside Apple's walls, leave it as HEIC. Everywhere else, convert.
How to convert HEIC to JPG
You have a few easy options, no Photoshop required.
Use a browser converter (fastest)
A client-side tool like convertheictojpg.net or TheImageCDN's converter converts right in your browser, nothing is uploaded to a server. Drop the files, grab the JPGs. Best for a quick batch.
On a Mac: Preview
Open the HEIC in Preview, then File > Export and choose JPEG. Set the quality slider high. Done, no extra software.
On an iPhone: share as JPG
Copying photos out through the Files app, or setting Settings > Camera > Formats to "Most Compatible", makes the iPhone hand over JPGs instead of HEIC.
On Windows: Paint
With the HEIF extensions installed (below), open the .heic in Paint and Save As JPEG.
What you lose in the convert
Converting to JPG is one-way. Beyond a little generational loss (JPG is lossy), you drop the HEIC-only data: 10-bit colour crushes to 8-bit, and depth, transparency and Live Photo motion are stripped out. Keep the HEIC original if you might re-edit later.
Opening HEIC on Windows
Windows does not read HEIC out of the box. Two Microsoft Store pieces fix it:
- HEIF Image Extensions — free, handles the container.
- HEVC Video Extensions — about $0.99, and it is the part that actually decodes the compressed image data.
Install both and Windows Photos and Paint open .heic files like anything else.
HEIC and websites: do not upload it directly
This is where HEIC bites people hardest, so it gets its own warning.
Never upload raw HEIC to a website
Chrome, Firefox and Edge do not render .heic images, mostly because of HEVC patent licensing, not a technical gap. Upload a HEIC straight to your site and most visitors see a broken image. And that is unlikely to change soon, the industry is moving to AVIF instead.
For the web, convert to a web-native format:
- JPG — safe, universal, fine for most photos.
- WebP — smaller than JPG, supported everywhere modern.
- AVIF — the best compression (it is AV1, HEIC's web-safe cousin), now broadly supported.
Better still, let an image CDN handle format conversion and delivery automatically, so every visitor gets the best format their browser supports without you juggling files. That is the same image-delivery discipline that keeps a site fast and its Core Web Vitals clean.
And if your site runs on WordPress, the whole convert-compress-serve routine can be automated with a plugin. I have laid out the exact image optimization workflow I run on every site.
Final take
HEIC vs JPG is not really a fight. It is a division of labour.
HEIC is the better storage format: smaller, richer, built for the Apple devices most photos are taken on. JPG is the better sharing format: older, larger, and understood by literally everything.
So stop choosing one. Shoot and store in HEIC. Convert to JPG (or WebP/AVIF for the web) the moment a photo needs to travel. That is the whole answer, and it costs you nothing but a converter bookmark.
Common questions
Is HEIC better than JPG?
On paper, yes, HEIC gives smaller files, 10-bit colour and extra data like depth and Live Photos. In practice it depends on where the photo is going. For anything leaving the Apple ecosystem, JPG's universal compatibility usually wins. Best of both: store HEIC, share JPG.
Can I open a HEIC file on Windows?
Yes, with a small setup. Install Apple's free HEIF Image Extensions from the Microsoft Store, plus the HEVC Video Extensions (about $0.99) that actually decode the image data. After that, Windows Photos and Paint open .heic files normally.
Does converting HEIC to JPG lose quality?
A little. JPG is lossy, so a conversion adds minor generational loss, though a single high-quality export usually looks identical. You also lose HEIC-only data: 10-bit colour drops to 8-bit, and depth, transparency and Live Photo motion are stripped. Keep the HEIC original if you may re-edit.
Is HEIC the same as HEIF?
No. HEIF is the container format (an open MPEG/ISO standard); HEIC is HEIF with the image compressed using HEVC (H.265), which is what Apple ships with the .heic extension. All HEIC is HEIF, but not all HEIF is HEIC.
Should I turn off HEIC on my iPhone?
Only if you constantly share to non-Apple devices and the conversion step annoys you. In Settings > Camera > Formats, choose "Most Compatible" to shoot JPG instead. Otherwise keep "High Efficiency", you save roughly half the storage and can convert individual photos when needed.
Why is my HEIC file not opening?
The app or system you are using cannot decode HEVC. On Windows, install the HEIF and HEVC extensions; on older software, or non-Apple browsers, convert the file to JPG first. A broken image on a website almost always means a HEIC was uploaded without converting.
