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.
Most grid tools are either too basic (fixed grid size, no customization) or require downloading desktop software. OnlineGridMaker runs entirely in your browser โ no install, no signup, no image uploads. Your photos stay on your device.
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.
CodeClimate 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.

Automated analysis tools: SonarQube, CodeClimate, and Codacy detect code-level debt automatically: cyclomatic complexity, code duplication, dependency staleness, and coverage gaps. These tools supplement but don't replace the architectural and business-logic debt that requires human judgment to identify and document. - Source: dev.to / 3 months ago
