My kid drew a dinosaur. Every "turn it into a puzzle" tool I found wanted an account, or uploaded the photo to their server. So I built one that runs entirely in the browser — pick a photo, get a printable A4 sheet with real jigsaw cut lines. Photos never leave the device. No signup, no watermark. Would like feedback on the cut lines specifically — mine are 1px and I'm not sure they survive a cheap inkjet.   submitted by   /u/No_Skirt9446   to   r/WebApps [link]   [comments]
