Overgrid

Add a grid to any image. Instantly.

Overgrid places a precision grid on any reference photo so you can transfer proportions to canvas, panel, or paper. Import from your gallery or shoot with your camera. Set rows, columns, and line weight. Done.

Customize everything. Choose grid color, opacity, and line thickness. Add diagonals for composition analysis. Turn on numbering to track your squares. Crop your image to match your canvas aspect ratio before you grid — no guesswork, no wasted paint.

Smart where it matters. Adaptive contrast reads your image and picks grid colors that stay visible on any background. Value study breaks the image into tonal levels so you can plan light and shadow before you start. Temperature overlay maps warm and cool zones across your composition.

Save your setups as presets. One tap to apply your favorite grid configuration to any new project. Switch between canvas sizes, grid densities, and color schemes without rebuilding from scratch.

Export at full resolution. Save or share your gridded image at up to 4096px for printing at any size. Free users export at 1024px with up to three projects. Premium unlocks unlimited projects, full resolution, custom colors, presets, and every analysis tool.

No account. No cloud. No ads. No subscription. Everything happens on your device. Your images stay yours. One-time purchase, use it forever.

Built for painters, illustrators, and anyone who works from reference. Whether you are scaling up a small sketch or transferring a photograph to a large canvas, Overgrid gets the grid out of your way so you can focus on the work.
