Mosaic engine guide

Start

The tool opens with a sample picture of coloured peaks under a gold sun, already broken into triangles by the Low poly preset.

What you need

• A current browser. Chrome, Edge, Firefox and Safari all draw it.
• A picture, if you want your own. Any picture the browser can open works. Big ones are fit to 1,600 pixels on their long side, or 1,000 on a phone.

Your first result

1. Open Mosaic engine. The sample is already there as a low-poly picture.
2. Press Image A to open a picture, or drop one on the frame. Or keep the sample.
3. Under Presets, press Stained glass, Honeycomb or any other. The picture is built again at once.
4. Drag Cell count and let go. More cells keep more detail; fewer make bigger, bolder pieces.
5. At the top of the panel, press Save PNG to keep it, or Copy to put it on the clipboard.

Good to know

• The PNG is named mosaic- and a number, at the picture's working size: the size shown after source in the line under the Image buttons.
• The PNG and the copy hold the flat PNG picture only. It is standard range (SDR), not HDR.
• Letting go of a slider builds the picture again with fresh random points, so the layout changes a little each time. Generate does the same on its own.
• Your picture is kept on this device, and every lab tool that takes a picture opens with it, until you press × on its tile.
• On a phone the controls sit in a bar at the bottom of the screen. Tap the bar to open them.
