GridMaker is a powerful yet intuitive web-based tool designed to help artists, photographers, and designers overlay customizable grid lines on their images. Whether you're working on art composition, design reference, or
precise layout planning, GridMaker provides professional-grade features with an easy-to-use interface.
Core Capabilities:
Upload any image and instantly apply a fully customizable grid overlay. Control every aspect of your grid with precision: adjust rows and columns from 1 to 20, fine-tune line width for subtle or bold grids, and choose custom
colors to match your workflow. The real-time preview ensures what you see is exactly what you get.
Advanced Features:
Transform your images with built-in adjustment tools including scaling, rotation, and drag-to-position functionality. Enable cell labels for precise grid reference, toggle diagonal lines for composition assistance, and apply
grayscale filters for better visual analysis. The fullscreen preview mode provides an immersive editing experience.
Professional Export Options:
Export your gridded images in multiple resolutions - SD (1x), HD (2x), or UHD (3x) - ensuring crisp, print-ready quality. Choose from standard paper formats including A0, A1, A2, A3, and A4, with support for both portrait and
landscape orientations. Save as PNG for lossless quality or JPG for smaller file sizes.
Perfect for:
- Artists transferring sketches and references
- Photographers analyzing composition
- Designers creating precise layouts
- Educators teaching visual principles
No installation required - completely browser-based and free to use.
Nice tool!!! Simple, focused utilities like this can become surprisingly popular.
Quick security question from a browser app perspective.
Since users upload images directly, how are you handling file validation and processing?
• Are you validating MIME types and file signatures, not just file extensions?
• Do you strip metadata like EXIF data before export to avoid leaking location or device info?
• Are uploads processed fully client-side, or does any image data touch your server?
If everything runs in the browser with no server-side storage, that’s a strong privacy advantage. Making that explicit on the site could increase user trust, especially for photographers working with sensitive client images.
Lightweight tools win when they are not only easy, but also safe.
