Frequently Asked Questions
Common questions about these online art tools and their free and Pro workflows
Are all online art tools free to use?
Every tool has a free core workflow with no account required. The available free result depends on the tool: some provide standard-resolution downloads, while others provide an interactive preview or calculation. Each tool page identifies any Pro-only export before you use it.
What extra capabilities does Art Grid Maker Pro add?
Pro unlocks 4K ultra-high-resolution exports, transparent PNG overlays for Procreate/Photoshop, print-ready multi-page 300 DPI PDF files, advanced diagonal/composition guides, and unlimited cloud presets.
Do reference images get uploaded to a cloud server?
No. All image processing, perspective math, color quantization, and canvas rendering happen 100% client-side in your web browser. Your photos and reference artworks never leave your local machine.
Can I use outputs from these tools for commercial art or client commissions?
You can use the grids, measurements, and worksheets you generate in your own projects. You remain responsible for having permission to use any reference image or other source material, especially for published or commercial work.
