How to Make Custom Emojis on iOS 18

Apple announced custom AI-generated emojis in iOS 18 and a lot of people got excited. Then they tried to use it and discovered the reality: it's called Genmoji, it requires Apple Intelligence, and Apple Intelligence has requirements that will immediately disqualify a significant chunk of iPhone users.

Here's the unfiltered breakdown — and the alternative that works on any device, right now.

What Apple Actually Shipped

Genmoji is real. You describe an emoji in text, and Apple's on-device AI generates it. You can type "disappointed cat with a birthday hat" and get a custom emoji. That part is genuinely cool.

But here's what the announcement didn't lead with:

Device requirements: Genmoji requires Apple Intelligence. Apple Intelligence requires an iPhone 15 Pro, iPhone 15 Pro Max, any iPhone 16 model, or an iPad / Mac with an A17 Pro or M-series chip.

If you have an iPhone 14, iPhone 15 (non-Pro), or anything older? No Genmoji. Doesn't matter that you updated to iOS 18.

Software requirements: You need iOS 18.2 or later (Genmoji wasn't in the initial iOS 18 release — it arrived in 18.2). And you need to have Apple Intelligence enabled in Settings, which required opting into a waitlist initially.

Where it works: Genmoji are available in Messages, and increasingly in other apps — but they're not standard emoji files. They're Apple's proprietary format. You can't export them as a PNG and use them on Discord, Slack, or anywhere outside Apple's ecosystem.

That last point is the one that frustrates people the most. You make something in Messages, and you can't take it anywhere else.

Who This Actually Affects

The population of people Genmoji doesn't serve is large:

• Anyone on an iPhone 15 or older (non-Pro)
• Anyone on Android (obviously)
• Anyone who wants to use custom emojis on Discord, Slack, Telegram, or any non-Apple platform
• Anyone who wants to share a custom emoji as a file — for stickers, reactions, profile pictures, downloads
• Anyone outside the US where Apple Intelligence features were initially restricted

This is the classic Apple move: ship a headline feature, quietly surround it with asterisks. The headline is "iOS 18 custom emojis." The asterisks are what we just covered.

The Alternative That Works Right Now

EmojiCreator.ai is a web app. It runs in any browser — on your iPhone, your Android phone, your old MacBook, your Windows laptop, whatever. No special chip required. No Apple Intelligence. No software version requirements.

You upload an image. The AI transforms it into custom emojis you can use anywhere. Download them as PNG files with transparent backgrounds, already sized for wherever you need them.

The output is an actual file you can use anywhere:

• Upload it to Discord as a custom server emoji
• Add it to a Slack workspace
• Use it as a Telegram sticker
• Set it as a profile picture
• Share it anywhere files can be shared

No ecosystem lock-in. No device requirements. No waiting for a feature to roll out to your region.

How to Make a Custom Emoji on Any iPhone

Here's the process with EmojiCreator, which takes about a minute:

1. Open Safari (or any browser) on your iPhone
2. Go to emojicreator.ai
3. Upload an image you want to turn into emojis
4. The AI generates multiple emoji variations from your image
5. Pick the ones you like
6. Download — already sized and transparent

That's it. Works on iPhone 11. Works on iPhone 16 Pro Max. Works on your kid's old iPad. Works on Android. The device doesn't matter.

When Genmoji Is Actually Fine

To be fair: if you have a compatible device, Genmoji is convenient for quick reactions inside iMessage. You don't have to leave the app. You don't need to download anything. For one-off moments in Apple's ecosystem, it's a decent experience.

But it's narrow. It's a feature for one specific communication context on a subset of Apple devices.

If you want custom emojis that work everywhere, that you can actually use as files, that aren't limited to whatever Genmoji's style produces — you need something else.

The Honest Take

Apple built Genmoji as a demo for Apple Intelligence, not as a comprehensive custom emoji solution. It's impressive technology. It's a limited product.

The frustration people feel when they update to iOS 18 expecting custom emojis and hit the Apple Intelligence paywall is legitimate. You were told you'd get something. The fine print changed the deal.

The good news: the feature you actually wanted — generate a custom emoji, download it, use it wherever — has existed independently of Apple's ecosystem for a while. It runs in your browser. It works today. And it produces files you actually own and can use anywhere.
