Perler Bead QR Code Generator

Yes, when the contrast is high, the light border is kept, and every module is correct. Scan the preview on screen with your phone first, then scan the finished piece before you iron it — fusing flattens the beads and can soften the edges.

One module is one bead, plus the light border. A 29×29 board is 841 beads; the tool counts the dark and light beads separately and rounds each color up to whole 1,000-bead bags.

Medium (M) is the default and a good balance. Higher levels (Q, H) survive more missing or misplaced beads but make the grid bigger, which can push you onto more pegboards. Lower levels keep the pattern smaller.

Yes. Mini beads are 2.6 mm, so the same grid finishes at roughly half the size of midi, which lets a bigger version fit a smaller finished piece. Pick Mini under bead size to see the real dimensions.

The longer the link, the larger the QR version and the more modules it needs. A 29×29 board holds a version 1 code with a 4-bead border or a version 2 code with a 2-bead border. Shorten the link, lower the error correction to L, or tile several pegboards — the tool shows how many boards the grid spans.

Yes, as long as the dark color is clearly darker than the light one — scanners read dark modules on a light background. Inverted codes (light on dark) fail on many phones. When in doubt, keep black and white.
