What every slider does, the best values to start with, and recipes for different styles.
Every slider and option in Photo From Emoji shapes the final artwork. This guide explains what each control does, suggests good starting values, and gives ready-made “recipes” for different styles. Treat it as a cheat sheet for getting exactly the look you want.
| Setting | Effect | Good starting point |
|---|---|---|
| Analysis Window | Detail / resolution | 7–10px |
| Output Emoji Size | Final image size | 12px |
| Match Tolerance | Colour accuracy vs variety | 8 |
| Allowed Empty Space | Emoji density | 70% |
| Background Colour | Fills gaps behind emojis | On, light colour |
| Display Mode | Layout style | Grid |
| Hide Black/Transparent | Skips dark/empty areas | Off (on for dark photos) |
What it does: sets the size of each scanned block. Smaller = more blocks = more detail and more emojis, but slower. Larger = fewer blocks = chunkier, faster.
When to lower it: when faces or fine detail look mushy and you want sharper definition. When to raise it: when you want a bold, abstract poster look or the render feels slow on your device.
What it does: controls how large each emoji is drawn, which sets the dimensions of your downloaded image. It changes the output resolution, not how the photo is analysed.
Tip: raise this before downloading if you intend to print the artwork or use it as a large banner; keep it modest for quick social posts and small file sizes.
What it does: sets how strict the colour matching is. Low tolerance keeps colours faithful but repeats a small set of emojis. High tolerance allows looser matches, adding variety and a more playful texture.
Lower it for realistic, colour-accurate results. Raise it when the image looks flat or repetitive and you want more emoji diversity.
What it does: filters which emojis can be used based on how much of their tile they fill. A lower value favours solid, dense emojis; a higher value also permits airier ones with gaps.
Tip: if the mosaic looks patchy or holey, reduce the allowed empty space so only fuller emojis are used.
What it does: when enabled, paints a chosen colour into the gaps behind the emojis. Disable it for a default or transparent backdrop.
Tip: match the background to your photo’s dominant tone for a seamless finish, or pick a contrasting colour to make the emoji shapes pop.
Grid gives clean rows and columns and is the most readable. Mosaic packs emojis more organically for a textured feel. Chart arranges them in a stylised, analytical layout. Start with Grid, then experiment.
What it does: skips very dark or empty regions so they are not filled with heavy black emojis. Ideal for photos on dark backgrounds where you want the subject to stand out cleanly.
Analysis Window 5–7px, Match Tolerance 5–8, Allowed Empty Space 60%, Grid mode, background matched to skin tone. Crop tightly around the face first.
Analysis Window 12–16px, larger Output Emoji Size, Match Tolerance 10–14, Grid or Mosaic mode. Great for high-contrast logos and graphic shapes.
Match Tolerance 15+, Allowed Empty Space 80%, Mosaic mode. Expect a colourful, scattered mix of many different emojis.
Enable Hide Black/Transparent, keep Match Tolerance moderate, and choose a dark background colour so the subject reads clearly.
| Problem | Try this |
|---|---|
| Looks too blurry / not detailed | Lower the Analysis Window |
| Too repetitive, few emojis | Raise Match Tolerance |
| Colours look wrong | Lower Match Tolerance |
| Patchy with holes | Lower Allowed Empty Space |
| Render is slow | Raise the Analysis Window or use a smaller image |
| Dark areas look like black blobs | Enable Hide Black/Transparent |
