Convert HEIC to JPG without uploading your photos
A photo can open normally on an Apple device and still be rejected by an upload form that accepts only JPEG. HEIC and JPG are different encodings: changing the filename extension does not convert the picture. Make a separate JPEG copy with a local export tool, then check the copy against the destination's requirements.
Refentra currently accepts JPEG, PNG and static WebP images. It does not decode HEIC. The options below use Apple's built-in tools for the conversion; you can use Refentra for further preparation after exporting a supported file.
On a Mac: export a JPEG with Preview
- Open the HEIC photo in Preview.
- Choose File, then Export, and select JPEG in the format menu.
- Choose a quality setting that keeps the detail you need.
- Save the converted copy under a new name or in a separate folder.
If the required format is hidden, Apple documents holding Option while opening the format menu. Preview also supports exporting several selected images from one window. See Apple's Preview conversion instructions.
On a Mac: use Finder for a quick conversion
Select the image in Finder, open its context menu, and choose Quick Actions followed by Convert Image. Select JPEG and the size you need. Apple explicitly lists HEIC-to-JPEG conversion as a supported use of this action. Available actions depend on the file and enabled extensions; Preview is an alternative when the command is absent. See Finder Quick Actions.
On an iPhone with the Preview app
Open the image in Preview. Use the actions menu beside its filename, choose Export, and select JPEG. If a size slider is available, choose a setting appropriate for your use. These steps apply to the Preview app documented in Apple's iOS 26 guide; devices with older software can have different options. See exporting images in Preview on iPhone.
A camera setting changes future photos
On supported iPhones and iPads, the camera format setting named Most Compatible makes subsequent photos use JPEG. This is useful when your regular destination requires JPEG, but it does not convert the HEIC photos already in your library. Apple also notes that some sharing or USB-import methods may automatically convert media; inspect the received file instead of assuming conversion occurred. See Apple's HEIF and HEVC guidance.
Check the exported copy before sending it
- Open it and check orientation, colors, fine text and important details.
- Check the actual file format, pixel dimensions and byte count.
- Keep the original if you may need to export again at a different quality.
- Check metadata separately when location or camera details should remain private.
JPEG is a lossy format, so a new export is not a promise of identical pixels. A different encoding also does not guarantee a smaller file. A locally performed conversion avoids sending the photo to a conversion website; your existing cloud-photo or folder-sync settings are a separate matter.
If the resulting JPEG exceeds an upload limit, use the target-size compressor. For hidden location data, use the JPEG metadata remover. Our upload troubleshooting guide explains when dimensions or accepted formats are the real cause of a rejection.
