Maze from Path generator

This browser-based maze generator to create a puzzle for a pen-and-paper adventure. It lets you turn a single continuous line into a maze: upload a simple black-and-white image (one path) or draw the path on a pixel canvas, and the app produces a perfect maze (one unique solution) whose shortest path exactly follows your line. Everything runs locally in your browser—no sign-ups, no uploads, no ads, no nonse —plus PNG/SVG export, adjustable cell size and wall width, and a reproducible random seed. You can also just download the html and run it offline.

Great for:
scavenger hunts, treasure hunts, escape room puzzles, ARGs, tabletop RPG one-shots, classroom worksheets, You can export vector SVG walls for laser cutting or plotters (Cricut/Silhouette) and tweak in Illustrator/Inkscape.

• Convert image to maze / image-to-maze tool

• Maze from drawing / line-to-maze converter
