How to Convert HEIC to PNG on iPhone (3 Methods)

Need to convert iPhone photos from HEIC to PNG? Whether you're trying to upload to a site that doesn't accept HEIC or need a universally compatible format, here are three methods that work right on your iPhone.

Method 1: Use HEICtoPNG in Safari (Recommended)

1. Open HEICtoPNG.com in Safari on your iPhone
2. Tap the upload area and select Photo Library
3. Choose one or more HEIC photos from your camera roll
4. The converter processes them instantly in your browser
5. Tap Download to save the PNG to your Files app

Why this works best: No app to install, completely private (files stay on your device), and you get actual PNG output — not JPEG like most auto-conversion methods.

Method 2: Change Camera Settings to Avoid HEIC

Prevent HEIC files from being created in the first place:

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

Note: This changes your camera to save as JPEG, not PNG. For PNG specifically, you still need to convert. Also, HEIC files are about 50% smaller, so switching to "Most Compatible" will use more storage.

Method 3: Use the Shortcuts App

1. Open the Shortcuts app on your iPhone
2. Tap + to create a new shortcut
3. Add these actions: Get Images from Input → Convert Image (to PNG) → Save to Photo Album
4. Name it "Convert to PNG" and add it to your Share Sheet
5. Now you can select any photo, tap Share → Convert to PNG

Best for: Frequent conversions without opening a browser. Takes a few minutes to set up but saves time long-term.
