Image to emoji mosaic guide
What is Emoji Mosaic?
A mosaic turns an image into a grid of colored emoji cells. This is the reverse of emoji-to-ASCII examples, which turn one emoji into text.
Ready to Create Emoji Art?
Start with the horse sample, then choose Emoji Mosaic in Options.
For an image made of emoji, open the image editor, load an image, then choose Options > Generation Mode > Emoji Mosaic and select Generate ASCII Art. To turn one emoji shape into character art, open an emoji gallery detail and choose Open recipe in editor on its Standard ASCII result. That link keeps the gallery's pinned Twemoji source. Direct emoji query links still render your device glyph, which can differ.
For the detailed horse below, use Sampling Width 60, Emoji Size 4, Emoji Set Squares, Transparent Pixel Emoji White Square and contrast 150%. Leave other adjustments neutral. This produces 15 symbol columns. Choose Coarse mosaic in the editor for five columns at size 12 and neutral contrast. Open recipe in editor keeps the image and these starting settings.
There is no arbitrary emoji picker in Upload. For an emoji outside the gallery, you can upload an image of a glyph you have permission to use. Newer Unicode emoji may be missing from a device's fonts.
Example Emoji Mosaic
Emoji Mosaic Result
Emoji Mosaic: sampling width 60, Emoji Size 4, squares set, transparent-cell symbol "⬜". Final columns = ceil(width / Emoji Size); rows depend on source aspect ratio.
Brightness 100%, contrast 150%, saturation 100%, hue 0, sepia 0%, inversion off. Dithering does not apply to this mode.
Open this recipe in the editor to keep this source, mode and settings. Browser resampling and fonts can differ from the built preview. Copy/TXT retain text; PNG uses black text on white at 12 px monospace, at least 1.2 line spacing and 20 px padding, independent of screen theme.

How It Works
Emoji Mosaic groups the resized image into square cells. It averages adjusted RGB values with transparency, chooses a color category, then selects the closest stored brightness in that category from the chosen Emoji Set. If the set has no matching category, it uses brightness alone. It does not recognize objects, emotions or meaning.
- Sampling Width resizes the source; Emoji Size sets the square cell size in that raster.
- Partial cells at the edges are retained. A 60-pixel width and size 12 produce five emoji columns.
- Cells below 20% average opacity use Transparent Pixel Emoji. Other cells blend the remaining transparency with white.
- Selected Unicode emoji are joined into rows. Their drawn appearance depends on the display font.

Frequently Asked Questions
What types of images work best for emoji mosaics?
Images with clear subjects, strong contrast, and vibrant colors work best. Simple compositions and logos often produce the most striking results.
Can I save and share my emoji mosaics?
Use Copy or TXT for editable emoji text, or PNG for a rendered image. Save the result before closing or reloading the page; the app does not save an artwork history.
How do I keep a shared mosaic aligned?
Copy and TXT preserve characters, spaces and line breaks, not the receiving app's styling. Use a fenced code block in a README or chat, or a preformatted monospace text area. Keep leading/trailing spaces and disable wrapping. Unicode blocks, lines and emoji need suitable fonts and may occupy different widths.
