Grid Maker is an online toolkit for artists who want to plan, transfer, and scale artwork with greater accuracy. Its free browser-based grid maker lets users upload a reference image, choose the number of rows and columns, adjust line color, thickness, and opacity, and optionally add cell labels. Gridded images can be downloaded as PNG or JPG for printing or digital use, without signup. The tool supports JPG, PNG, GIF, and WEBP uploads and serves artists, students, teachers, illustrators, beginners, and muralists.

Alongside its main grid generator, Grid Maker offers photo grids, transparent overlays, printable grids, and Instagram feed planning. Additional tools include aspect-ratio, proportion, and canvas-size calculators, perspective-grid generators, portrait proportion guides, a mural-scaling calculator, an art projector, a coloring-page generator, a paint-by-number generator, worksheets, and a poster splitter. The site also provides grid-method tutorials, a drawing challenge, and an art gallery. Grid Maker Pro is available with a free trial and adds features such as higher-resolution and transparent exports, tracing, and print-ready studio sheets.
