Check first: your iPhone may already send a JPG
Depending on your device, browser, and settings, choosing a picture from the photo library inside a web page may hand over a compatible copy automatically. Try choosing the photo on our page first. If it is accepted, there is nothing to convert.
If the page says the file is HEIC or HEIF, use one of the methods below.
On a Mac
Apple describes two built-in ways to save a JPEG copy of a HEIF photo on a Mac.
- In Photos: select the picture, choose File > Export, and pick JPEG as the format. Photos saves a new file and leaves the library version unchanged.
- In Preview: open the HEIC file, choose File > Export, select JPEG in the Format menu, and save. Give the copy a clear name so you can tell the two apart.
- Open the new JPG and check it at full size before uploading.
On an iPhone, iPad, or Windows PC
If the photo will not upload from your iPhone, the simplest dependable route is often to send it to a computer and export a JPEG copy there. On Windows, opening HEIC files can require an extra codec. If your photo app can open the image, use its Save as or Export option to save a JPG copy.
Changing the format for future photos
On an iPhone, Settings > Camera > Formats > Most Compatible makes the camera save new photos as JPEG. Apple notes that this applies only to photos you take afterwards. Pictures already in your library stay in HEIF and still need a copy.
Why renaming the file does not work
Changing “photo.heic” to “photo.jpg” changes only the name. The data inside is still HEIF: a file’s format is set by how it was saved, not by its extension. Some browsers may still open a renamed file and others will refuse it as unreadable, so the outcome is unpredictable. Export a real copy instead.

| A HEIC photo and a Mac | Export a JPEG copy from Photos or Preview |
| A HEIC photo and only an iPhone | Try choosing it on our page; if refused, send it to a computer and export a copy |
