# Blank Image Generator — Full Documentation

> blankimage.net is a free, privacy-first online image generator. It creates blank, solid color, gradient, grid, pattern, and profile images entirely in-browser — no server upload, no registration, no watermark. Users can customize dimensions (up to 10,000×10,000 pixels), colors, shapes, gradients, and patterns, then instantly download as PNG. Available in 6 languages: English, Chinese (Simplified & Traditional), Japanese, Spanish, and Portuguese.

## About

Blank Image Generator was built to solve a simple but common problem: developers, designers, and content creators frequently need placeholder images, solid color backgrounds, device wallpapers, or social media templates — but most existing tools require sign-ups, add watermarks, or upload data to servers.

blankimage.net generates everything client-side using HTML Canvas. Your images never leave your browser. The tool is completely free with no usage limits, and supports a wide range of image types from simple solid colors to complex multi-layer patterns.
