Questions

Frequently asked

Is GridMaker Pro free to use?

Yes. You can upload a reference image, customize the grid, and export standard PNG, JPG, or PDF files without creating an account.

Is my reference image uploaded to a server?

No. GridMaker Pro processes the image locally in your browser. The photo is used to draw the preview and export canvas, but it is not sent to an image-processing server.

Golden ratio or rule of thirds?

Thirds is faster and more forgiving. Golden ratio places interest slightly closer to centre for a calmer classical balance.

Can I calculate phi divisions first?

Yes. Open the golden ratio calculator, enter your width and height, then return here with the same overlay.
