What is Image to Emoji Mosaic?

Image to Emoji Mosaic converts photographs into artwork made entirely of emoji characters. Each pixel region is matched to the closest emoji by color, creating a fun mosaic effect. Adjust tile size, emoji set, and style, or pick a one-click preset, to get different looks. Your images never leave your device.

Each tile is averaged for colour and matched against an emoji palette filtered by category: faces, nature, food, animals, hearts, geometric shapes, or skin tones. Smaller tiles give finer detail at the cost of a wider mosaic; the output renders as monospace text for chat apps, a downloadable PNG, or a plain .txt file.

How to use

1. Step 1 — Upload an image (PNG, JPEG, or WebP). The tool divides it into a grid of small regions.
2. Step 2 — Adjust the tile size (smaller tiles = more detail, larger = faster). Tap one or more emoji sets to blend their palettes, add a Sepia, Invert, or Contrast effect, or turn on the underlay to show your photo behind the grid. You can also pick a one-click preset, switch the style to squares or hearts, and type an exact column count.
3. Step 3 — Copy the mosaic as text, save it as a .txt file for sharing, or download a rendered PNG for posts and avatars.

When to use

• Replying to a friend's photo on Discord or Slack with the photo redrawn in emoji.
• Making a profile banner that reads as art on phones where custom images break.
• Building a low-bandwidth visual for forum signatures or text-only environments.

Result

A social media manager uploads a sunset photo, sets the tile size to 12px for good detail, and copies the emoji mosaic into a Slack message — the sunset appears as rows of orange, yellow, blue, and purple emoji squares.

FAQ

Why does the mosaic look noisy with small tile sizes?

Small tiles mean more emojis per row, and emojis only come in a fixed set of base colours. The closer two adjacent tiles' source colours are, the more random the picked emojis look. Try a 16-24px tile for cleaner output.

Can I post the emoji output on Twitter or Instagram?

Twitter accepts the text version but breaks lines at around 280 characters. For Instagram captions, either use the PNG export or shorten the mosaic to about 12 columns wide so it stays on one line per row.

Why are some emojis missing from my mosaic?

A category filter restricts the palette to one set of tones, so the mosaic uses only those. Tap several sets to blend their palettes, or use All Emojis for the widest range and the closest colour match.

Do emojis render the same on every device?

No. Apple, Google, Samsung, and Microsoft each ship their own emoji set, so the mosaic looks slightly different on iOS versus Android. The PNG export preserves the look from your own device.

What's the best image to start with?

High contrast photos with clear large shapes — sunsets, portraits, logos, flags — translate well. Detailed scenes with fine line work get muddled because each emoji is essentially a single coloured pixel.
