# Image to sticker

Remove a plain background, wrap what's left in a thick white outline, and save a transparent PNG ready for chats, posts and printing. Your picture never leaves your browser.

## From picture to sticker

1. **Add a picture with a plain background:** a drawing on white paper, a product on a backdrop, a character on a flat colour.
2. **Check the background colour.** It is detected from the picture's edges; if it is wrong, press Pick on the picture and click the background.
3. **Tune the cut.** Raise the tolerance until the background is gone, and lower it if parts of your subject vanish.
4. **Style the outline** and save the PNG. It is trimmed to the sticker with room for the shadow.

This is colour keying, not AI cut-out: it works on flat backgrounds, not busy photos. With the colour removed only where it touches the edges, matching colours inside your subject (white eyes, say) are kept.

## Printing your stickers

Many print shops accept a transparent PNG for die-cut stickers, and a thick outline gives the cutting blade a forgiving margin around your design.

## Questions

**What do tolerance and edge softness do?**

Tolerance is how far a colour may differ from the background and still be removed. Edge softness fades the next band of colours out gradually, so edges look smooth instead of jagged.

**Why is part of my subject missing?**

Those parts are close to the background colour. Lower the tolerance, or choose Where it touches the edges so enclosed areas are kept.

**Can I make stickers of any picture?**

Your own drawings and photos are fine. Characters, logos and other people's artwork belong to their owners, so ask first, especially before printing or selling stickers.
