HEIC vs JPG: Which Photo Format Should You Keep?
Compare HEIC and JPG for iPhone storage, editing, sharing, metadata, compatibility, and long-term photo management.

HEIC is normally the better file for your iPhone to keep. JPG is normally the easier file to send somewhere else. That is the useful difference.
You do not have to choose one forever. Keep the HEIC original and make a JPG copy when a website, Windows app, printer or family member cannot open it.
The quick answer
HEIC usually keeps similar photo quality in a smaller file and can store extra Apple photo features. JPG works almost everywhere, which makes it the safest sharing format.
For a normal camera photo, do not convert HEIC to PNG just because PNG sounds high quality. It will often be much larger and still cannot turn the image back into something better than the original.
How to make a JPG copy
Keep the HEIC file
Treat it as the original. Put converted files in another folder.
Drag the photo into How to Convert
You can add one file or a whole group of iPhone photos.
Choose JPG and click Convert
Use the normal quality setting first. There is no benefit in repeatedly converting the result.
Open the JPG where you need it
Check that it opens, looks the right way up and has the quality you expect. Then send or upload that copy.
Common problems
The HEIC will not open
The app or device does not include HEIC support.
Make a JPG copy on a device that can read the original.
The JPG is larger than expected
The quality is very high or the photo contains a lot of fine detail.
Lower the quality slightly and compare it at normal viewing size.
The Live Photo stopped moving
Only the still image was converted.
Keep the original Live Photo files for motion playback.
Frequently asked questions
Is HEIC better quality than JPG?
It can keep similar visible quality in less space. The exact result depends on how each file was made.
Which one should I upload to a website?
Use JPG when you want the least chance of a compatibility problem, unless the site says it accepts HEIC.
Can Windows open HEIC?
Newer Windows setups can with the required image extensions, but JPG remains more universally supported.
Should I change my iPhone camera to JPG?
Only if compatibility is more important to you than storage efficiency. Converting copies later lets you keep both benefits.
Extra: Why HEIC support can still be awkward
HEIC is a container built around newer image compression. The reason it sometimes fails is not that the photo is broken; the receiving device may simply lack the software needed to decode it.
If you edit photos, keep the original because it gives you the best starting point for later exports. Make fresh JPG copies from that original rather than from an older JPG copy.
