Convert HEIC to JPG on iPhone (Free, No App)

Your iPhone saves photos as HEIC to keep file sizes small, but the moment you email one, add it to a web form, or move it to a Windows PC, it often gets rejected or simply won’t open. Grabio is a free iOS Shortcut that converts any HEIC photo to a standard JPG right on your iPhone — no app to install, no account, and nothing ever leaves your device.

Why your iPhone’s HEIC photos get rejected

Since iOS 11, iPhones shoot in HEIC (High Efficiency Image Container) by default because it stores the same photo at roughly half the size of a JPG. The trade-off shows up the moment a picture has to leave your phone: attach a HEIC to a job-application form, an online store’s photo field, or an email to a Windows user, and you’ll often hit an “unsupported file type” error or a thumbnail that won’t open. JPG opens on virtually anything, which is exactly what you need when a photo has to travel off your iPhone.

How to convert HEIC to JPG on iPhone with Grabio

Add Grabio to your iPhone once — it’s a free Apple Shortcut with no App Store download and no sign-up. Add Grabio to your iPhone.
Open the Photos app (or any app showing the HEIC photo) and pick the picture you want to convert.
Tap the Share button — the square with an upward arrow.
Scroll down the share sheet and tap Grabio.
Choose Photo → JPG from the Grabio menu.
Your JPG saves straight to the Photos app and you’ll see a “Saved ✓” notification.

Is it private and free on iPhone?

Both. The conversion runs entirely on your iPhone using Apple’s own image tools, so your HEIC photo never leaves your device and never touches a server. Grabio is 100% free with no account and no login — it’s a single Apple Shortcut you add once and keep, with nothing to buy later.

HEIC to JPG on iPhone: FAQ

Does this work on iPhone without wifi?

Yes. Because the conversion happens on your iPhone and nothing leaves the device, Grabio works fully offline — on a plane, on the subway, or with no signal at all. You only need a connection the first time you add the Shortcut.

Where does the JPG save on my iPhone?

The new JPG lands in your Photos app, in the same Recents album as the rest of your pictures. Your original HEIC stays untouched, so you keep both versions until you decide to delete one. If you can’t spot it right away, it’ll be the newest item at the bottom of Recents.

Does converting to JPG lower quality on iPhone?

The JPG keeps your photo’s full resolution, so it looks the same on screen. JPG is a less space-efficient format than HEIC, so the converted file is usually a little larger — that’s the trade-off for a photo that opens everywhere.
