DESIGN OS
The design toolkit built for professionals who think in systems.
Design OS is a browser-first creative utility suite inside the ZIBADIS ecosystem. It covers color theory, WCAG accessibility, modular typography, layout grids, geometric ratios, and gradient engineering — all local, offline-capable, and free.
Fourteen tools. One design system.
Color Palette
Color theory, harmonics, color spaces (RGB, CMYK, HSL, LAB, Pantone), and palette generation for digital, print, textile, and industrial contexts.
Color Contrast
WCAG AA/AAA checker, text and image contrast, breathing space theory, positive/negative space balance, Yin-Yang and Zen principles.
Type Scale
Modular scale calculator, kerning, spacing, font families and weights, typeface vs logotype, raster vs vector fonts, print and digital formats.
Classic Grid
Column calculator, triangle and polygon meshes, 2D/perspective/3D grids, design system spacing, golden ratio hidden grids, and deconstruction.
Standard Ratios
Golden ratio, aspect ratios, paper dimensions, social media sizes, artwork safe zones, print and environmental standards, resizing rules.
Gradient Builder
Linear, radial, conic and mesh gradients with CSS output. Material patterns, 3D surface shading, GIF optimization, and motion design considerations.
Social Media Sizes
Complete dimension reference for Instagram, LinkedIn, X, YouTube, TikTok, Facebook, Telegram, Pinterest, and Behance with live preview.
Font Tester
Upload .woff, .ttf, or .otf fonts and preview at any size, weight, tracking, and line-height. Full Farsi and Latin support.
DPI & Print Size
Convert between pixels and print dimensions. Upload images to see printable sizes at 72, 150, 300, and 600 DPI with quality indicators.
Spacing System
Generate consistent spacing scales from a base unit. Linear, golden ratio, or power-of-2 progression. CSS variables and Tailwind output.
Book Spine
Calculate spine width from page count and paper thickness. Reference table for common combinations.
Paper Sizes
Complete reference: ISO A/B series, US standard, envelope sizes, business cards — all with mm, inches, and pixels.
Banner & Ad Sizes
IAB display ad standards, billboard dimensions, email template widths, web banner sizes — all with visual reference.

Part of ZIBADIS AI OS
Built for the ZIBADIS Network
Design OS is one of the professional applications inside the ZIBADIS AI Operating System (zibadis.ir). It serves designers, developers, and content creators who need fast, reliable design calculations without leaving the browser. The entire ZIBADIS ecosystem shares a unified design language, authentication layer, and data model.
Browser-First, Offline-Ready
No installation, no account required. All tools run entirely in your browser with zero server dependency. Your color choices, grid calculations, and gradient codes stay private — nothing is uploaded. Works on desktop, tablet, and mobile. Supports both English and Persian with full RTL layout adaptation.
