As answered by people managing OnlineGridMaker and Codility.
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.
