Free Online Grid Maker for Artists - Add a grid overlay to any photo for drawing, no cropping

Hey Product Hunt! I’m Erin, the maker of Grid Drawing. I built it for artists, beginners, and art teachers who use the classic grid method and want a simple way to turn any photo into a gridded reference—without cropping or distorting the original image. Grid Drawing doesn’t just add a grid overlay. It also helps you recreate the same grid on paper with ruler-friendly measurements, so there’s no math to figure out. What it does: - Smart recommended grid density right after upload (then fine-tune rows/columns) - Perfectly square cells with no cropping or distortion (padding is added instead) - Drag to reposition the image when padding is added, so you control where the extra space goes - Full grid styling (color/opacity/width/solid/dashed/dotted) + optional labels - Optional black & white filter to reduce visual noise - Export PNG or a print-ready PDF (PDF can include a step-by-step paper drawing guide) It’s free, no signup, watermark-free, and processed locally in your browser (your image isn’t uploaded or stored). This is a fresh launch, so if you spot any bugs or rough edges, I’d really appreciate it if you comment with your device + browser and what happened. I read every message. Ask me anything!
