Since iOS 11, iPhones save pictures in HEIC (also called HEIF) by default. The format is genuinely good: it stores the same visual quality as JPG in roughly half the space. The trouble is compatibility. Many job portals, email clients, older Windows versions, printing kiosks and CMS uploaders still expect JPG or PNG, so a HEIC upload either fails or shows a blank thumbnail.

Option 1: change the camera setting

On the iPhone open Settings, Camera, Formats and choose "Most Compatible". New photos will then be saved as JPG. This does not fix the pictures you have already taken, which is why a converter is still useful.

Option 2: convert existing photos

Open the Image Converter, drop one or many HEIC files onto the upload area, choose JPG (or PNG if you need transparency preserved) and press Convert. Each file is processed separately, so one unreadable picture never blocks the others. Download them one by one or as a single ZIP.

JPG or PNG?

  • JPG is the right choice for ordinary photos: small files that every site accepts.
  • PNG is lossless and larger. Use it for screenshots, logos or images with sharp text.
  • WebP is smaller than JPG and fine for your own website, but some older software still cannot open it.

Will I lose quality?

Any conversion from HEIC to JPG involves a second lossy compression step, so choose the highest quality setting if the picture matters. For everyday uploads and sharing the difference is invisible. If you want zero loss, convert to PNG; the file will simply be bigger.

What about the date and location?

Camera metadata such as the time a photo was taken is usually kept, which helps your gallery sort pictures correctly. If you are worried about privacy, remember that location data can be inside the file; strip it with your phone's share options before posting publicly.

Troubleshooting

If a file is rejected, check that it really is a photo taken on the phone and not a renamed download. Live Photos contain a short video as well; only the still image is converted. Very large batches are best split into groups of fifty so the browser stays responsive.

Questions people ask

Will converting delete my HEIC originals? No. Conversion produces new files. Keep the originals if you want the smaller size.

Is the converted JPG larger? Usually yes, by roughly 30 to 100 percent, because JPG is a less efficient format than HEIC.

Do I lose the live part of a Live Photo? Yes; only the still image is saved as a JPG.

Can I convert many photos at once? Yes. Add them together and download the results as one ZIP.

Making your iPhone save JPG in future

If you often share photos with Windows users, switch the camera format to "Most Compatible" in Settings, Camera, Formats. The trade-off is larger files and less editing headroom for features that rely on HEIC.

Sharing from iPhone without converting

Many iPhone sharing paths convert automatically when you send by email or choose "Most Compatible" in the share sheet's options. When that does not happen, or when you upload to a website through a browser, a converter bridges the gap in seconds with the HEIC to JPG converter.
