Apple loves sneaking in the odd unannounced feature, and with iOS 26's big September release, it seems there's plenty that we missed.

Every iPhone update comes packed with a slew of new features, but while it seems that the next one is out before we even get used to this one, you can't complain that Apple doesn't keep us fed well.

There was plenty to discuss when it came to iOS 26, but despite grumbles of Liquid Glass being an aesthetic overhaul and the typical complaints about battery drain as some clamored to revert back to iOS 18, others have been perfectly happy with what's on offer.

It seems some of you were busy slamming spatial effects and call screening to notice there's a brand-new app hiding in plain sight. You might've spotted a new icon for the mysterious Preview app.

Mac users will likely know what Preview is all about, but for those who don't, it's not a sneak peek at future iPhones or a tease of iOS 27. Instead, Preview is all about editing and works in a similar way to its macOS counterpart. You can edit and annotate images and PDFs, as well as scan physical documents, fill out forms using Autofill, and export files in a number of formats.

Preview automatically installs when you update to iOS 26, and even though we're sure some of you will moan about it taking up space, it's a handy app to have around.

When you open Preview, you'll be given basic options like New Document, Scan Document, and a mini version of your phone's Files app.

Preview is similar to your traditional imaging editing from past versions of iOS, meaning you can write or draw on a photo. There's even an option to remove a background, which makes Preview invaluable without having to resort to third-party apps like Photoshop.

Perhaps the best feature is that iPhone users can open a PDF, and Preview will automatically detect boxes that need to be filled in. You can also add signature and text boxes without needing Adobe Acrobat, although we'll admit that Preview is a little more limited.

As noted by Tom's Guide, scanning documents is a breeze, which is helpful if you need to send over the likes of your passport or other forms of ID. Simply pointing your camera at a page will see it scanned into your iPhone and conveniently converted into a document.

The site reminds us that while these image editing options have been available for a while on iPhone, having them conveniently bundled in one place alongside a scanning option streamlines the whole process. According to Tom's Guide, Preview could become the go-to editing app for iPhone fans.
