Ways to Use a Grid Overlay

Drawing from a Reference

Add a drawing grid over a reference image to break it into smaller sections and reproduce proportions, shapes and object placement more accurately.

Photo Composition

Add grid lines and diagonal guides to a photo to review balance, alignment and subject placement.

Image Mapping

Use labels such as A1 and B2 to identify, compare and discuss specific areas of an image more precisely.

Custom Grid Overlay Options

Create a full grid overlay or add only vertical or horizontal grid lines, with up to 50 rows and 50 columns.
Choose solid, dashed or dotted grid lines and adjust their color, width and opacity.
Create square grid cells when needed, then add A1-style labels or diagonal guides in either or both directions.
Download the finished image as PNG, JPEG or WebP while preserving its original dimensions.
The grid is added locally in your browser, so your image does not need to be uploaded to a remote editing server.
