!Scroll to zoom, drag to pan. Keep the quiet margin when you use the code — scanners need it. The picture lives in the QR’s redundant pixels, so some phones will struggle. Always test before printing at scale.

What a scanner reads back.

Version6

1–40. Bigger holds more text. Version 6 is the largest without alignment blocks cluttering the middle.

Error correction

Higher levels tolerate more of the picture.

InvertDesign for a black background instead of white.Rotate 180°Moves the finder patterns to the other corners.

Darkest allowed0

Lifts the blacks. Helps when the image has large dark regions that swallow the code.

Brightest allowed255

Drops the whites. Helps when large light regions wash the code out.

Each colour counts as light or dark. A module can only be drawn in a colour of its own polarity, so the code keeps its contrast while the picture keeps its hue.

Embed the pictureOff gives you a plain QR code.Solid finder patternsKeep the corner squares, alignment squares and timing lines whole instead of dithering them. This is what a scanner locks onto — leave it on unless you want the raw look.Dither timing & formatLet the dither run through the timing lines and the format strips, leaving only the finder and alignment squares solid. Less of the code cutting through your picture, at some cost to how easily a phone locks on.Dither middle alignment squaresVersion 7 and up scatter extra alignment squares across the middle of the code — right where a face sits. This gives those back to the picture and keeps only the four a small code would have had: the three corners and the outermost square. Nothing changes below version 7.Diffuse the imageOff is a flat threshold. On is smoother, with far more detail.Diffuse module errorPushes each locked module's error out to its eight neighbours before the main pass. Only turn this off to see what it does.Spend detail where it mattersJudge each module's patch of the picture: flat regions render as one solid block, and the dither's detail goes to the parts that carry something — a face, an edge, an eye.

Subdivision5× → 25 px

Each module becomes N² pixels. The centre carries the data; the rest carry the picture.

Break threshold0.0%

Releases the worst-fitting data pixels back to the picture. Past a point the code stops scanning.
