Short answer: HEIC is the iPhone photo format — it keeps similar quality to JPG at roughly half the file size, but many Windows PCs, Android apps, websites and online forms cannot open it. JPG works everywhere. To convert, use a free HEIC to JPG converter, or set your iPhone to Most Compatible so it saves JPG from now on.
What is HEIC?
HEIC stands for High Efficiency Image Container. It is Apple’s version of the HEIF standard and has been the default camera format on iPhone and iPad since iOS 11. It uses modern compression so photos take up less space on your phone and in iCloud.
HEIC vs JPG at a glance
| HEIC | JPG | |
|---|---|---|
| File size | About 40–50% smaller | Larger |
| Quality at same size | Better | Good |
| Opens on Windows / Android | Often needs extra software | Yes |
| Accepted by websites and forms | Often rejected | Almost always |

When HEIC causes problems
- Sending photos to Windows or Android users who cannot preview them.
- Uploading to job, exam or visa portals that only accept JPG.
- Inserting photos into Word, PowerPoint or older editing software.
- Printing at shops whose machines do not read HEIC.
How to convert HEIC to JPG (any device)
- Open the PixelTight HEIC to JPG converter.
- Drop in your .heic photos (up to 20 at once).
- Click Convert to JPG and download the files or a ZIP.
The conversion runs in your browser, so private photos are not uploaded anywhere.
How to make your iPhone save JPG instead
- Open Settings.
- Tap Camera → Formats.
- Choose Most Compatible.
New photos will be JPG. Your existing HEIC photos stay as they are, so convert those with the tool above. Keep in mind JPG photos take more storage space.
Other tips
- iPhone photos often include your GPS location. Remove it with the metadata remover before sharing publicly.
- Need a smaller file after converting? Use compress to 200 KB.
- Turning photographed documents into one file? Use JPG to PDF.
Frequently asked questions
Is HEIC better quality than JPG?
At the same file size HEIC looks better. At their usual settings both look very similar, but HEIC files are about half the size.
Does converting HEIC to JPG lose quality?
A small amount, because JPG is also compressed, but at high quality settings the difference is not visible in normal use.
Can Windows open HEIC files?
Windows 10 and 11 need an extra extension to open HEIC. Converting to JPG avoids the problem.
How do I stop my iPhone from taking HEIC photos?
Go to Settings, Camera, Formats and choose Most Compatible.
