FAQ
Answers before you start gridding.
The short version: no install, no account, no upload workflow. Open the tool, apply an overlay, adjust it, and export the reference you need.
Basics
Getting started
What is Grid Maker Pro?
Grid Maker Pro is a browser tool for placing drawing, composition, perspective, design, and geometry overlays on top of reference images.
Is it really free?
Yes. The tool is free to use, does not require an account, and does not add watermarks to exported images.
Do I need to install anything?
No. Open the website in a modern browser. There is no desktop app, plugin, extension, or license key to manage.
What is the fastest way to learn it?
Use the Get Started page first. It covers the upload, overlay, adjust, and export flow without going into every advanced option.
Privacy
Image handling
Do you upload my image to a server?
No. Overlay generation happens in the browser. Your reference image does not need to leave your device for the grid to be applied.
Can I use client or commission references?
Yes, subject to your own contract terms. The no-upload workflow is intended for private references, commissions, classroom images, and studio work.
Do I need an account for privacy controls?
No. Privacy is not tied to login. The core workflow works without an account.
Overlays
Choosing grids
What overlays are included?
There are 82 overlays across basic drawing grids, artist guides, composition, advanced composition, dynamic symmetry, perspective, specialty grids, sacred geometry, typography, design templates, and architecture.
Which overlay should I use first?
Use square grid for drawing transfer, rule of thirds for quick composition, golden ratio for proportional refinement, Loomis head for portraits, and perspective grids for scenes with depth.
Can I stack multiple overlays?
Yes. Use stacking when a single grid does not answer the whole question, such as combining a composition grid with a portrait or perspective guide.
Where is the full catalogue?
The full browseable catalogue is at /grid-library/.
Export
Files and printing
What image formats can I upload?
Use common browser-supported formats such as JPG, PNG, and WebP. Very large files may be limited by your browser and device memory.
What do exports look like?
The exported image is a working reference with the selected overlay visible on top of the source image.
Can I print the result?
Yes. Export the reference, then print it like a normal image. For drawing, matte paper usually produces less glare than glossy paper.
Troubleshooting
When something feels off
The grid is hard to see. What should I change?
Change the line color first, then adjust opacity and line width. Red or orange usually works on mixed images; white works on dark images.
The overlay does not line up with my subject.
Use transform controls. Most overlays need to be moved, rotated, or scaled to fit the actual crop and subject angle.
Where do I report a bug?
Use the contact page. Include the browser, device, image type, overlay name, and what you expected to happen.
Still need help?
Send the exact overlay name, browser, device, and a short description of the issue.

Illustrative composites of how the tool gets used in practice — not quotes from named individuals.
Bookmarked on the studio computer. The deep-link reopens with the exact overlay configured — no clicking through menus mid-session.
Free and browser-only is the right shape for this kind of tool. I keep three tabs open during any project — one per overlay I'm comparing.
Lower friction means I actually use it, not save it for special occasions. Every overlay one click away.
Open Grid Maker Pro
Drop a reference image. Pick an overlay. The rest is in your browser.
