Convert HEIC to JPG for Windows on iPhone (Free)

You emailed a set of iPhone photos to a Windows PC and they won’t open — because your iPhone saved them as HEIC, a format Windows frequently can’t read without an extra extension. Grabio is a free iOS Shortcut that converts any HEIC photo to a universal JPG right on your iPhone, with no app to install and nothing ever leaving your device.

Why your iPhone’s HEIC photos won’t open on Windows

To save storage, your iPhone shoots in HEIC (High Efficiency Image Format) by default instead of JPG. It looks fine on your iPhone, but Windows 10 and 11 often can’t open HEIC unless someone installs Apple’s HEIF image extension from the Microsoft Store — something locked-down work PCs usually block. On the PC you get a blank thumbnail or a “can’t open this file” error, even though the photo is perfectly good. Converting to JPG on your iPhone first sidesteps the whole thing, because JPG opens on every Windows PC with no add-ons.

How to convert HEIC to JPG for Windows on iPhone with Grabio

Add Grabio to your iPhone once — it’s a free Shortcut, no app and no account. Get the free Shortcut here, then tap Add Shortcut.
Open the Photos app and select the HEIC photo you want to send to your PC.
Tap the Share button (the square with the up arrow).
Scroll down the share sheet and tap Grabio.
Choose Photo → JPG from the Grabio menu.
Wait for the Saved ✓ notification — the new JPG lands in your Photos app right next to the HEIC original.
Now email the JPG, save it to OneDrive or Google Drive, or move it over a USB cable — it will open on any Windows PC. If the photos are heavy for email, you can reduce the photo file size on your iPhone first.

Is Grabio private and free on iPhone?

Yes on both. The conversion runs entirely on your iPhone using Apple’s own image tools — the photo is never sent to a server, and Grabio never sees your files. It’s 100% free with no login, no account, and no subscription; the only thing that ever leaves your iPhone is the JPG you choose to send to your PC.

FAQ: converting HEIC to JPG on iPhone

Does this work without wifi on my iPhone?

Yes. Because the conversion happens on your iPhone with built-in tools, you don’t need wifi or any signal — turn on Airplane Mode and it still works.

Where does the JPG save on my iPhone?

It saves to your Photos app, in the same place as the original HEIC, so both versions sit side by side. From there you can email or transfer just the JPG to your Windows PC.

Will my Windows PC open the JPG from my iPhone?

Yes. JPG is the most widely supported image format there is — it opens in Windows Photos, File Explorer previews, browsers, and Office with no extra extension needed. That’s the whole point of converting before you send.
