OnlineGridMaker — Free Grid Overlay Tool for Artists
How often each product is chosen within a category, 0–100% relative to the other.

As answered by people managing Google Open Source and OnlineGridMaker.
OnlineGridMaker's answer:
-Unlike most grid tools that only offer basic square grids, OnlineGridMaker combines customizable grid overlays (adjustable rows, columns, color, opacity) with perspective guides for 1-point and 2-point drawing. It also offers optional cell labels (A1, B2 style). Everything runs 100% locally in the browser — no image uploads, no signup, no data ever leaves your device.
OnlineGridMaker's answer:
-Most alternatives either require installing software, force you to create an account, or upload your images to a server. OnlineGridMaker is completely browser-based, free forever with no premium tier, and processes everything on your device. Just open the page, upload a reference image, and start gridding in seconds. It's faster, more private, and zero friction compared to desktop apps or account-gated web tools.
OnlineGridMaker's answer:
-Artists, illustrators, art students, and hobbyists who practice drawing from reference photos — especially those learning proportion, composition, and perspective. Also useful for architects, designers, and educators who need quick grid overlays for teaching or planning purposes.
OnlineGridMaker's answer:
-Built by an independent developer who noticed that most free grid tools were either too basic (fixed grids only) or required downloading software. The goal was simple: a professional-grade, free grid overlay tool that respects user privacy by processing everything locally in the browser. No tracking, no uploads, no strings attached.
OnlineGridMaker's answer:
-Pure HTML, CSS, and JavaScript — no frameworks, no backend, no dependencies. Hosted as a static site on Cloudflare Pages for global CDN delivery. The tool uses the HTML5 Canvas API for rendering grids and generating downloadable PNG images client-side.
OnlineGridMaker's answer:
·Art students using it for figure drawing and still life proportion practice
·Freelance illustrators who need quick grid references before starting digital paintings
·Art teachers incorporating it into classroom demonstrations
·Comic artists using perspective guides for background layouts
