What is Grid Maker?

Grid Maker is a free, open-source web tool that helps artists draw by overlaying a customizable grid on any reference image. Upload your photo, crop it, adjust the grid, apply filters, and download the result in high resolution.

Perfect for:

• Traditional artists using the grid method for proportional drawing
• Art students learning composition and proportions
• Anyone who wants to transfer a reference image to canvas accurately

Features

• Multiple image input methods - Drag & drop, copy/paste (Ctrl+V), file picker, drag from browser, or paste a URL
• Precision cropping - Powered by Cropper.js with aspect ratio presets, rotation, flip, and zoom
• Customizable grid - 1-50 rows/cols, 10+ color presets, custom colors, adjustable thickness and opacity
• Line styles - Solid, dashed, or dotted lines
• Grid extras - Cell numbering with edge labels, center crosshair, diagonal lines
• Image filters - Original, Grayscale, Sepia, Scanner (high contrast B&W), High Contrast, Invert, Brightness, Warm, Cool
• Simple & Advanced modes - Toggle between basic controls and full configuration
• High-res export - Download as PNG or JPEG at 1x, 2x, or 3x scale
• Grid-only export - Export just the grid with transparent background
• Dark & Light themes - Smooth theme toggle with orange accent, defaults to dark
• Multi-language - English, Spanish, Portuguese, French with auto-detection
• Responsive design - Works on desktop and mobile, sidebar becomes bottom drawer
