Mac and iPhone share Apple's ecosystem, so macOS can open HEIC files without any extra software. But that doesn't mean PNG is useless on Mac. PNG is the right choice when you need to share photos with Windows users, upload to platforms that don't support HEIC, edit images without generation loss, or preserve transparency data.
The fastest way to convert HEIC to PNG on a Mac is through the browser — no Automator scripts, no terminal commands, no subscription tools required. WildandFree's HEIC to PNG converter works in Safari, Chrome, and Firefox and processes files locally on your Mac.
Method 1: Convert HEIC to PNG Using Your Mac's Browser (Recommended)
Open Safari (or Chrome/Firefox) and go to wildandfreetools.com/converter-tools/heic-to-png/. Drag your HEIC files into the drop zone, click "Convert to PNG," and download the results. No account, no signup, no iCloud access required.
This method works on every Mac from MacBook Air to Mac Pro, running macOS Mojave (10.14) or later. It's completely free with no file limits, and your photos never leave your Mac — the conversion runs inside the browser using your Mac's own processor.
Safari note: Safari on Mac fully supports the conversion engine. If you get an error, try Chrome as a fallback — though in most cases Safari works fine on modern Macs.
Method 2: Use Preview to Export HEIC as PNG (No Extra Tools)
macOS's Preview app can open HEIC files and export them as PNG. Here's how:
- Double-click the .heic file — it opens in Preview automatically.
- Go to File → Export.
- In the Format dropdown, select PNG.
- Click Save.
Preview's export is lossless — the PNG quality matches the browser converter. The limitation is that Preview handles files one at a time. For batch conversion, you need either the browser tool (drag multiple files at once) or an Automator workflow.
Batch with Automator: Open Automator → New → Quick Action → set workflow receives "image files." Add "Change Type of Images" action, set output to PNG. Save, and right-click any HEIC file in Finder to run it. This works but requires initial setup.

The browser converter is the easiest batch method. Select multiple HEIC files in Finder (Command+A for all, or Command+click to select specific files), then drag the entire selection into the browser drop zone. All files convert in one session.
For large batches from an iPhone photo library transferred to your Mac:
- Connect your iPhone via USB or use AirDrop to transfer files to your Downloads folder
- Open the folder in Finder, select all HEIC files (Command+A)
- Drag to the browser converter tab
- Download each PNG as it finishes
If you transferred photos from iCloud Downloads, they may still be in .heic format even on Mac — this approach works the same way.

Converting HEIC to PNG vs JPG on Mac — Which Is Better?
On Mac, both formats open natively in Preview, Safari, and Photos. The choice comes down to your use case:
| Use case | Better format |
|---|---|
| Sharing with Windows users | Either (JPG is smaller) |
| Uploading to a website | JPG (smaller) or WebP (even smaller) |
| Editing in Photoshop / Pixelmator | PNG (lossless, no re-save degradation) |
| Preserving screenshots or graphics | PNG (supports transparency) |
| Email attachment | JPG (smaller file size) |
| Archiving master copies | PNG (lossless, future-proof) |
If you need JPG specifically, the HEIC to JPG on Mac guide walks through the same process for that format.
Do Your Photos Stay on Your Mac?
Both methods keep your photos entirely on your Mac. Preview is a local app — it never connects to the internet during export. The browser converter processes files inside Safari using your Mac's processor — files are never uploaded to any server.
This is especially important for personal photos or photos containing sensitive information. Unlike some web-based services that upload your files to a cloud backend, both of these approaches are entirely local.
For more privacy-sensitive conversions, the browser converter is actually more transparent about this — you can verify in Safari's network panel that no file uploads are occurring during the conversion process.

Open Free HEIC to PNG ConverterFrequently Asked Questions
Can Mac open HEIC files without converting?
Yes — macOS Mojave and later support HEIC natively. Preview, Photos, and Safari all open .heic files. You only need to convert if you're sharing with Windows users, uploading to a platform that doesn't support HEIC, or editing in software that requires PNG or JPG.
Does Preview convert HEIC to PNG losslessly?
Yes. When you export as PNG in Preview, the output is lossless — every pixel is preserved from the original HEIC file. PNG's lossless compression means no quality is sacrificed regardless of which tool you use.
How do I batch convert HEIC to PNG on Mac without Automator?
Drag multiple HEIC files from Finder into the WildandFree HEIC to PNG converter at wildandfreetools.com/converter-tools/heic-to-png/. Select all files in Finder with Command+A, then drag them all to the browser drop zone. All files convert in one session.
