Hi HN,

I built this because I wanted a simple tool to overlay grids on reference photos for drawing, but most top search results were either ad-ridden or required uploading images to a server.

GridMakers is different:

Privacy-First: It uses HTML5 Canvas to process everything locally in your browser. No image data is sent to my server.

Specialized Modes: I added presets for Portrait (A4 crop), Mural (10x10 scaling), etc.

Tech Stack: Built with Next.js and Tailwind.

It's free and I'm just trying to make a useful utility. Feedback welcome! Link: https://gridmakers.app
