Built for useful grids

A precise overlay for checking alignment and composition

A grid overlay makes spacing and alignment visible without permanently changing your original image. It is useful for drawing references, composition checks, layout review, measurement, and classroom demonstrations.

Use a high-contrast color when the photo is busy, reduce opacity for a subtle guide, or add major and sub-grid lines when you need both broad divisions and finer placement.

The combined image and transparent overlay are generated locally. No account is needed and the source image never leaves your device.
