Send a photo from your iPhone over WhatsApp and your friend on Android or an older phone sometimes sees a blank square, a “can’t open this file” error, or a thumbnail that never loads — that is HEIC, the format your iPhone saves photos in. This guide shows you how to convert any iPhone photo to a universal JPG that opens everywhere, using a free Shortcut called Grabio that runs fully on your iPhone with no app to install.

Why your iPhone’s HEIC photos break on WhatsApp

Since iOS 11, your iPhone saves photos as HEIC because it packs high quality into a smaller file. The catch is that HEIC is not universal: many Android phones, Windows PCs, and some WhatsApp builds cannot preview or open it, so your photo lands as a broken image or a file the other person cannot download. You will see this most in group chats, where one person on an iPhone posts a photo and half the group cannot view it. Converting to JPG first avoids the whole mess, because JPG opens on practically every device and app.

How to convert HEIC to JPG for WhatsApp on iPhone

Once Grabio is installed, the whole thing is three taps and a few seconds on your iPhone. Here is the exact flow:

  1. Add Grabio to your iPhone once — it is a free Shortcut. Add Grabio to your iPhone.
  2. Open the Photos app on your iPhone and pick the HEIC photo you want to send.
  3. Tap the Share button — the square with the arrow pointing up.
  4. Scroll down the share sheet and tap Grabio.
  5. Choose Photo → JPG from the Grabio menu.
  6. Wait for the “Saved ✓” notification. Your new JPG is now in the Photos app.
  7. Open WhatsApp, attach the fresh JPG, and send it — it will open cleanly for your recipient.

Is it private and free on iPhone?

Both. Grabio converts your photo on-device using your iPhone’s own image tools, so the file never leaves your phone and there is no server involved at all. It is completely free with no account, no login, and no separate app cluttering your Home Screen.

FAQ: HEIC to JPG on iPhone

Does this work on my iPhone without wifi?

Yes. The conversion happens entirely on your iPhone, so you do not need wifi or mobile data to create the JPG. You only need a connection when you actually send the photo in WhatsApp.

Where does the converted JPG save on my iPhone?

The new JPG saves straight to your Photos app, next to your other pictures. When you open WhatsApp and tap to attach a photo, you will find it there ready to send.

Does converting on my iPhone lower the photo quality?

JPG compresses differently than HEIC, so there can be a slight change, but for a photo headed to WhatsApp — which re-compresses images anyway — it is not a difference you will notice on screen.
