Photo Grid for Sketch
OnlineGridMaker is a free browser-based tool that adds customizable grid overlays to any image โ designed specifically for artists, illustrators, art students, and anyone who practices drawing from reference photos.

Grid Overlay โ Add precise grids to any image with full control over rows, columns, line color, line thickness, and opacity.
Perspective Guides โ Built-in 1-point and 2-point perspective tools for accurate architectural and object drawing.
Cell Labels โ Optional row/column numbering for easy reference when transferring your sketch to paper or canvas.
Instant Download โ Export your gridded image as PNG or JPG and start drawing right away.
100% Local Processing โ All rendering happens in your browser using HTML5 Canvas. Your images are never uploaded to any server.
Completely free. No premium version. No signup required. Unlimited use.

OnlineGridMakerOnlineGridMaker'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 โ 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 โ 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 โ 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.
