What is a Grid Maker?
A grid maker is a drawing aid that places evenly spaced guide lines over a reference image. Artists use the grid method to compare small sections of an image, transfer proportions, and keep important edges aligned while sketching. OnlineGridMaker lets you choose rows, columns, line color, opacity, labels, diagonal guides, and grayscale mode, then download a clean PNG with the grid applied. Everything runs in your browser, so the original image never leaves your device.
