How to Convert HEIC to JPG on iPhone

1. Open ConvertHEIC.org in Safari or Chrome on your iPhone
2. Tap the upload area and select your HEIC photos from your photo library
3. Adjust the quality slider if needed (92% is recommended)
4. Tap "Convert" and wait a few seconds
5. Download your JPG files — it's that simple!

✅ Works entirely in your browser — no app to install, no files uploaded to any server

If you want future photos to be saved as JPG instead of HEIC:

1. Open Settings on your iPhone
2. Scroll down and tap Camera
3. Tap Formats
4. Select Most Compatible

⚠️ This only affects new photos. Existing HEIC photos won't be converted.

1. Open the Photos app and select the HEIC photos
2. Tap the Share button
3. Tap Save to Files
4. Open the Files app and locate the saved photos
5. Long-press a photo, then tap Convert (if available on your iOS version)

Note: This method is not available on all iOS versions and only works for individual files.

When you share photos via Mail or Messages, iOS can automatically convert HEIC to JPG:

1. Open Photos and select your HEIC images
2. Tap the Share button
3. Choose Mail or Messages
4. Select "Actual Size" to keep full resolution
5. The photos will be sent as JPG attachments

⚠️ This is slow for batch conversion and requires sending the photos somewhere.
