Art Grid Maker is a privacy-first, browser-based drawing and layout toolkit for visual artists, muralists, educators, and crafters. It runs entirely client-side (no artwork uploaded to servers) and provides free tools for the grid drawing method, reference preparation, proportion calculators, and craft graph generation. Pro plans unlock 4K exports, print-ready vector PDFs, transparent PNG overlays, and advanced measurement guides.

## Key Facts
- Cost: 100% free core tools with no watermarks and no registration required. Optional Pro plans ($8/month, $79/year, or $139 lifetime) unlock 4K exports (up to 4,096 px), print-ready 300 DPI vector PDFs, transparent PNG overlays, and advanced measurement field plans with a 14-day free trial and 30-day money-back guarantee.
- Authentication: No account, sign-up, email, or credit card required for any of the 20 free browser tools.
- Processing & Privacy: 100% client-side execution in the browser. Reference images, sketches, and photos are decoded and processed locally on the user's device and are never uploaded, stored, or sent to any remote server.
- Supported Inputs: JPG, PNG, WebP, GIF reference photos, camera snapshots, or blank canvas dimensions (inches, centimeters, millimeters, feet, meters, and pixels).
- Supported Outputs: Standard PNG and JPG (free, up to 1,500 px), 4K high-resolution PNG (Pro, up to 4,096 px), print-ready 300 DPI PDF documents (Letter, A4, Legal, A3, Tabloid), SVG charts (Crochet), and ZIP packages (Instagram tiles).
- Speed & Limits: Instant real-time rendering (<100ms adjustments); zero queue, runs offline once loaded.
## What Art Grid Maker is NOT
- Not an AI generative image creator or AI art generator: It does not generate text-to-image AI artwork, prompt-based AI art, or deepfakes; it provides mathematical layout grids and reference analysis tools for human artists.
- Not a cloud storage drive or image host: Reference images and photos are never uploaded, saved, or retained on servers.
- Not a desktop-only or native app: Requires no app store installation; runs entirely in modern web browsers across desktop, iPad, tablets, and smartphones.
- Not a monolithic subscription-locked editor: Every tool has a functional free tier with no forced registration, no watermarks, and no trial credit limits.
- Not a hardware optical projector: The Art Projector tool turns screens/tablets into tracing lightboxes, but cannot physically project light onto a distant wall without external projection hardware.
- Not an automatic vectorizer or auto-drawing bot: It does not draw or paint for you; it provides precision guides, outlines, and measurements for manual artistic execution.
