Convert HEIC to PNG on iPhone (Free, No Upload)

Your iPhone saves photos as HEIC, but plenty of editors, design tools, and collaborators expect a lossless PNG instead — and iOS gives you no built-in way to convert one. Grabio is a free iOS Shortcut that turns any HEIC into a PNG right on your iPhone, on-device, with no app to install and nothing ever uploaded.

Why iPhone HEIC photos are a problem for PNG work

HEIC keeps file sizes small, but it is the wrong format the moment you move into a real editing workflow. Many layered editors, transparency-based design tools, and older programs reject HEIC outright or silently flatten it into a lossy JPG — baking in compression artifacts every time you re-save. Graphic work, logos, print files, and anything you will edit more than once all call for PNG so the pixels stay exact. When a tool or a teammate asks for a PNG, you need a true lossless copy, not another squeezed export.

How to convert HEIC to PNG on iPhone with Grabio

Add Grabio to your iPhone once — it is a free Shortcut with no app, account, or login. Add Grabio to your iPhone.
Open the HEIC photo in the Photos app, or wherever the image is saved.
Tap the Share button.
Scroll down the share sheet and tap Grabio.
Choose “Photo → PNG” from the Grabio menu.
Your iPhone converts it on-device in a second, shows a “Saved ✓” notification, and drops the PNG into your Photos app.

PNG is lossless, which is exactly why it is larger than HEIC or JPG. If you only need broad compatibility and not editable, lossless quality, converting HEIC to JPG on iPhone makes a much lighter file.

Is Grabio free and private on iPhone?

Every conversion runs on your iPhone using Apple’s own image tools, so the HEIC never leaves the device — nothing is uploaded to a server, and no account or email is required. Grabio is 100% free with no limits, and because it works entirely on-device, it keeps converting even in airplane mode.

iPhone HEIC to PNG FAQ

Does this work on iPhone without Wi-Fi?

Yes. The conversion happens entirely on your iPhone, so no Wi-Fi, cellular data, or internet connection is needed — nothing is sent anywhere. It works the same on a plane, in a tunnel, or with signal switched off.

Where does the PNG save on my iPhone?

The finished PNG saves straight to your Photos app, and you will see a “Saved ✓” notification when it is done. From there you can drop it into any editor or share it wherever the lossless file is needed.

Will the converted PNG have a transparent background?

No — a camera photo is fully opaque, so the PNG looks pixel-for-pixel identical to the original, just in a lossless, widely supported format. PNG can hold transparency, but converting an existing photo does not remove its background; you get the same image with no quality loss.
