You're scrolling through your emoji keyboard, looking for something that isn't quite as heavy as the solid black heart, and there it is. The black heart outline emoji. It looks like a simple wireframe. Minimalist. Sharp. But if you’ve ever wondered why it exists alongside the solid version—or why it looks different on a Mac than it does on an Android—you’re not alone. Honestly, it’s one of those digital artifacts that people use constantly without realizing it has a totally different technical history than the "emo" black heart we all know.
Digital communication is messy. We think we're sending a specific vibe, but the person on the other end might see something completely different based on their operating system. This specific outline icon, often formally called the "Heavy Heart Exclamation Mark Ornament" or simply "White Heart Suit" in older Unicode documentation, has transitioned from a boring typographic symbol to a staple of the "clean girl" aesthetic and minimalist social media branding.
The Technical Weirdness of the Black Heart Outline Emoji
Unicode is the global standard that makes sure a "A" on my screen is an "A" on yours. But the black heart outline emoji (U+2661) is a bit of an oddball. Most people don't realize that the emoji we call the "black heart" (the solid one) was added to the official emoji set much later than the outlines. The outlines were originally part of a set of symbols for literal card games and typesetting.
Wait, why does that matter?
Because of this history, the way the black heart outline emoji renders is wildly inconsistent. On Apple devices, it’s a crisp, thin black line. On some older Android builds, it might not even show up as a colored emoji, appearing instead as a "glyph," which is just a black-and-white character. It’s basically the ghost of the emoji world.
If you’re using a Windows machine, you’ll notice the outline looks thicker, almost chunky. This lack of uniformity is exactly why it’s become a favorite for people who want to look "different" or "aesthetic" without trying too hard. It’s the "indie" version of the heart emoji.
Aesthetic Overload: How TikTok Reclaimed the Outline
Go to any Pinterest board about "clean desk setups" or "minimalist fashion," and you'll see it. The solid black heart is often associated with sadness, "dark academia," or being "edgy." It’s heavy. It takes up a lot of visual "weight" in a caption.

The black heart outline emoji is the opposite. It’s airy.
It’s used by creators who want to show appreciation without the intensity of a colored heart. If someone comments a solid red heart on your photo, it feels like a big gesture. If they use the black heart outline emoji, it’s more of a "cool, I like this" vibe. It’s subtle. You’ve probably seen it in Instagram bios where people list their city or their job title. It acts more like a bullet point than an emotion.
Modern Contexts for the Outline
- Minimalist Branding: Small businesses often use it in their "About Us" sections because it doesn't clash with their color palette.
- Professional Boundaries: It’s a "safe" heart. It’s less romantic than red, less "best friend" than yellow, and less "emo" than the solid black. It says, "I'm being friendly, but we aren't soulmates."
- Photo Captions: Specifically for black-and-white photography where a colored emoji would ruin the look.
It Isn't Actually One Thing
Here’s the kicker: there isn't just one black heart outline emoji. There are actually a few different characters that people mistake for it.
First, there’s the standard "White Heart Suit" (♡). Then, there’s the "Heart Decoration" (💟) which sometimes looks like an outline inside a purple box. Then you have the "Heavy Heart Exclamation" (❣) which sometimes glitches out in certain fonts to look like a heart outline with a dot.
According to Emojipedia, the site run by Jeremy Burge (who basically knows more about emojis than anyone on Earth), the way these symbols are categorized is constantly shifting. The black heart outline emoji actually sits in the "Dingbats" block of Unicode. That sounds like a 90s insult, but it’s actually a technical term for printer ornaments. This explains why it feels more like a piece of punctuation than a cartoon.
The Psychology of Empty Space
Why do we like the outline more than the solid version sometimes? Psychologically, an outline represents a "placeholder" or something "unfilled."

When you use the black heart outline emoji, you're leaving room for interpretation. It’s less "loud." If you send a "Thinking of you ♡" text, it feels lighter than a "Thinking of you ❤️" text. The latter feels like a demand for attention; the former feels like a gentle breeze.
I spoke with a social media manager for a major fashion brand last year who told me they strictly use the outline heart for their newsletters. The reason? "It doesn't distract from the product photography. It’s there, it’s a heart, but your eyes don't get stuck on it."
That’s the power of the outline. It’s invisible-adjacent.
Common Mistakes and Display Issues
You have to be careful. Because the black heart outline emoji is technically a "Legacy" symbol in some systems, it doesn't always play nice with every app.
Have you ever seen a weird box with an "X" in it? Or a question mark in a square? That’s called "tofu." No, not the food. It’s what happens when a computer doesn't have the font support for a specific character. Because the black heart outline emoji (U+2661) is an older Unicode character, some very old browsers or super-niche Android skins might not render it as a pretty emoji. They might just show a blank space.
If you’re using it for something super important—like your brand’s main logo or a crucial call-to-action—test it on both an iPhone and a Samsung first. You’d be surprised how often the "clean" look turns into a "broken" look.

How to Get It (Since It's Not on Every Keyboard)
Funny enough, despite being popular, the black heart outline emoji isn't always on the primary emoji picker. On iOS, if you go to the emoji keyboard, you’ll find the solid black heart easily. But the outline? You might have to use a workaround.
- Copy and Paste: Most people just search "heart outline" on Google and copy it from a site like Symbol.cc.
- Text Replacement: This is the pro move. Go to your phone settings (General > Keyboard > Text Replacement). Set it up so that when you type "hheart," it automatically replaces it with ♡.
- Character Maps: On a Mac, you can hit Command + Control + Space and search "Suit" to find the card game icons.
It’s a bit of a "if you know, you know" situation. Using the outline shows you’ve put in slightly more effort than just tapping the first red heart you saw.
The Evolution of Heart Meanings
We’ve come a long way since the red heart was the only option. Now we have a heart for every mood. The black heart outline emoji has found its niche in the "sophisticated yet detached" category. It’s the emoji equivalent of a minimalist apartment with one single Monstera plant and a beige couch.
It’s also surprisingly popular in the "alt" or "e-girl/e-boy" scenes on TikTok, though they tend to mix it with the solid black heart to create a layered look. Combining them—one solid, one outline—creates a sense of depth that a single emoji just can't match.
Where the Outline Heart Goes From Here
As we move into 2026, the trend toward "de-cluttering" our digital lives is only growing. The black heart outline emoji fits perfectly into this. We are seeing a move away from the hyper-saturated, bright yellow emojis of the 2010s toward more "glyph-like" symbols.
Will it ever be as popular as the red heart? Probably not. The red heart is the king of the keyboard. It’s the universal sign of love. But the outline isn't trying to be the king. It’s happy being the cool, quiet character in the corner of the room that everyone wants to talk to.
Your Next Steps for Emoji Mastery
- Audit your bio: Look at your social media profiles. If you’re using the solid black heart and it feels too heavy or "loud," try swapping it for the black heart outline emoji. It instantly makes the layout feel more professional and spacious.
- Check for "Tofu": If you’re a developer or designer, always ensure you have a fallback font like Arial Unicode MS or Sans-serif to ensure the outline renders correctly for users on older machines.
- Use it for "Soft" Approval: Next time you’re texting a colleague or a casual acquaintance, use the outline. It’s the perfect way to acknowledge a message without the "weight" of a colored heart. It signals "seen and appreciated" without any underlying romantic or intense emotional tones.
The beauty of the black heart outline emoji lies in its emptiness. It’s a literal vessel for whatever meaning you want to pour into it, without the baggage of traditional emoji colors. Give it a try in your next caption and see how it changes the vibe.
