People with an image to bead
Photos, memes, and illustrations all convert — no manual grid drawing.
Anyone who cares about backgrounds
Transparent PNGs are handled correctly so the background doesn’t eat beads.
People who want to compare looks
One image yields several options; pick the best before starting.

How an image becomes a bead pattern

Upload an image
Pick a photo or illustration; it’s read locally and not uploaded by default.
Set the bead width
Bead width sets the finished size and detail, with a live preview.
Choose a palette
Select the brand you own; colors map to the closest available codes.
Generate and export
Compare options, then export a high-res pattern with grid and color codes.

How to choose the key settings

Bead width
Use more beads for detailed images (portraits, complex art), fewer for icons.
Transparent background
PNGs with alpha keep the background out of the bead count for clean edges.
Color count
Fewer colors are cheaper and easier to build but less faithful — balance as needed.

Why one image gives multiple options

Fidelity and buildability usually conflict. DuoPinDou generates faithful, simplified, and dithered options at once and scores them, so you can compare and pick the one that fits your patience and materials.

What the export includes

High-res pattern PNG
With grid coordinates and a color legend, ready to print.
Bead-count list
Beads needed per color code, for easy prep.
Option scores
Fidelity and buildability scores to guide your choice.

Transparent backgrounds and privacy

Transparent PNG backgrounds are not counted as a color. Images are processed locally and not uploaded by default.
