What is Add Grid Overlay?
Add Grid Overlay draws a grid of evenly spaced horizontal and vertical lines across every page of a PDF. You control the spacing (in points) and the line color. The grid is drawn directly onto the page content using pdf-lib.
How to Use Add Grid Overlay
- Upload your PDF file.
- Set the grid spacing in points (default is 50pt) and optionally choose a line color as a hex code (default is
#cccccc). - Click Add Grid. The tool draws vertical lines at every x-interval and horizontal lines at every y-interval across all pages.
- Download the result as

What grid size should I use?
50pt grids are roughly 17mm (good for general alignment). 72pt grids align to 1-inch intervals. Smaller values like 25pt create dense grids useful for fine layout work.
