Emoji vs Sticker: What Is the Difference, and Which One Do You Actually Want?

By Pixmoji · Published September 12, 2026

People say "I made a custom emoji" and mean a sticker. They say "send me that sticker" and mean a Genmoji. The words blur, and the blur matters, because emoji and stickers are different things that live in different places, travel differently between phones, and are made with different tools. This guide sorts them out in plain terms: what an emoji actually is, what a sticker actually is, where Memoji and Genmoji fit, and which one you want for the thing you are trying to do.

The short version

• An emoji is a character. It lives in the Unicode standard like a letter, every phone has the same set, and nobody can add one to the keyboard.
• A sticker is a small transparent image. Anyone can make one, it can look like anything, and it is sent as a picture that chat apps display inline.
• Every "custom emoji" you have ever seen is a sticker, including Memoji stickers, Genmoji, and anything made in an emoji maker app like Pixmoji.

What an emoji is

Emoji are part of Unicode, the same standard that defines letters and punctuation. Each emoji has a code, the Unicode Consortium approves new ones roughly once a year, and every platform draws its own version of the same code: the red heart looks slightly different on an iPhone, an Android phone, and a Windows laptop, but it is the same character. That is why an emoji copies and pastes like text, scales with the font, appears in usernames and search boxes, and weighs nothing. It is also why you cannot make your own: there is no way to add a character to a standard that every phone on earth has to agree on.

What a sticker is

A sticker is an image file, usually a PNG or WebP with a transparent background, roughly 512 pixels square. Messaging apps display stickers inline at a large emoji-like size, let you collect them in packs, and often let you peel them onto messages or use them as reactions. Because a sticker is a picture rather than a character, it can look like anything: your face, your dog, a drawn character, a photo cutout. That freedom is the whole point, and it is also why stickers behave differently from emoji: they cannot go inside a line of text, they are sent as separate items, and a phone that does not support the sticker format shows them as ordinary images.

So what are Memoji, Genmoji, and "custom emoji"?

• Memoji are avatars you assemble from menus in iMessage. The Memoji "emoji" you send are stickers generated from the avatar, in Apple's cartoon style.
• Genmoji are generated by Apple Intelligence from a text description on iPhone 15 Pro and newer. They are drawn in Apple's emoji style and inserted from the emoji keyboard, so they feel like emoji, but technically they are stickers: on a non-Apple phone they arrive as images. See Genmoji vs custom emoji apps.
• Custom emoji from any emoji maker, Pixmoji included, are stickers too: illustrated, transparent, saved into packs. Pixmoji calls them emoji because that is what people search for and how they use them, but the thing in your WhatsApp sticker tab is a sticker.

None of this makes stickers second-class. It explains why they can be personal and emoji cannot, and why they need a place to live, which is the next section.

Where each one works

Which one you actually want

• A quick reaction inside a sentence: emoji. "See you at 8 🎉" is a job for a character.
• A reaction that is recognizably you, your dog, or your group's inside joke: sticker. Nothing else can be personal.
• A matching set of eight reactions in one style: sticker pack. Emoji come in one style, Apple's; stickers come in whatever you make.
• Something that works in a username, a subject line, or a spreadsheet: emoji. Stickers cannot go there.
• Something for WhatsApp that Android friends can also add: a sticker pack, installed. WhatsApp packs are cross-platform.

Making a sticker that feels like an emoji

The custom emoji people want is a sticker that reads as emoji: small, clear, expressive, transparent, one subject. Pixmoji is built for exactly that. Text to Emoji draws one from a few words, with the look in the words themselves, "sleepy cat, cute chibi"; Image to Emoji redraws a photo or a selfie as an illustrated sticker with the background removed. Stickers save into packs that install into WhatsApp with Install Pack and appear in the iMessage sticker drawer. Start with how to make your own emoji on iPhone, then making WhatsApp stickers for the pack side.

Common mix-ups

• "Why is my emoji a picture on my friend's phone?" It was a sticker or a Genmoji. On a phone that does not have the sticker integration, stickers arrive as images. WhatsApp packs are the exception: they work on both platforms.
• "Can I add my sticker to the emoji keyboard?" Not as a character. On iPhone, stickers live in the sticker drawer next to the keyboard, which is close enough for most people.
• "Why do emoji look different on Android?" Same character, different drawing. Stickers do not have this problem because they are a single image.
• "Is a GIF a sticker?" Cousins. GIFs are animated images sent the same way, usually without transparency and much larger. Sticker packs are lighter and built for reactions.

Quick answers

What is the difference between an emoji and a sticker?

An emoji is a Unicode character, the same on every phone and impossible to add to. A sticker is a small transparent image anyone can make, sent as its own item and collected in packs. Every custom emoji, including Memoji stickers and Genmoji, is technically a sticker.

Can I create my own emoji for the keyboard?

Not as a keyboard character. You can make custom stickers that behave like emoji in chats: Pixmoji generates them from text or a photo, and they live in the iMessage sticker drawer and WhatsApp sticker tab.

Is Genmoji an emoji or a sticker?

Technically a sticker drawn in Apple's emoji style. It inserts from the emoji keyboard on supported iPhones, and on other phones it arrives as an image.

Do stickers work on Android?

In WhatsApp, yes, as stickers and packs. In other apps they arrive as images, which still shows the picture.

Which is better for a group chat?

Emoji for quick inline reactions, a sticker pack for reactions that are personal to the group. Most active group chats end up using both.
