iOS 26 hides a clever toggle in Messages that speeds up photo sharing by sending a quick preview first. Here’s how it works and why you’ll want it on.
Sharing photos with friends and family on iMessage can sometimes feel slow, especially if you’re stuck on weak Wi-Fi or limited cellular data. With iOS 26, Apple has quietly added a hidden setting called “Send Low-Quality Photo Previews” that makes sending images much faster by sending a lightweight preview first.
If you’ve ever been frustrated waiting for a photo to send, this new toggle could be the fix you didn’t know you needed. Here’s how it works and how you can enable it.
Normally, iMessage sends the full-resolution photo, which guarantees the recipient gets the highest quality version. The downside? Large file sizes slow down transfers on weaker connections.
The new “Send Low-Quality Photo Previews” feature solves this by sending a compressed preview instantly, so your recipient can see the photo right away. The full-quality version downloads later in the background once your network improves.
It’s a smart compromise between speed and quality, making iMessage far more reliable when your internet connection isn’t.
Turning on this feature only takes a few seconds:
From now on, any photo you send through iMessage will first be delivered in compressed form, followed by the full-resolution image once it’s ready.

After you enable this feature, the iMessage recipient will initially see a pixelated or low-quality version of the photo you send, which will be automatically replaced by the full-resolution image once it is fully transferred.
However, if you have the low data mode enabled, don’t be surprised if only a low-quality version is sent. While this is done to help you save mobile data, it may affect image clarity in conversations.
This feature is ideal for:
The Send Low-Quality Photo Previews option in iOS 26 is one of the most practical updates for iMessage. It makes photo sharing almost instant, even when your connection isn’t.
If you often share photos on the go, this setting is worth turning on. The next time you see a pixelated photo in iMessage, don’t panic; the full-quality version is already on the way.
