About Chitrax

A privacy-first, browser-based image and PDF processing platform, built for people who value their data.

What Is Chitrax?

Chitrax is a free, all-in-one suite of image and PDF tools that runs entirely inside your browser. Resize images, compress photos, convert formats, remove backgrounds with AI, generate passport photos, enhance image quality, create PDFs from images, and merge PDF documents, all without uploading a single file to any server.

Why We Built It

Most online image and PDF tools require you to upload your files to remote servers. This means your personal photos, confidential documents, and sensitive images pass through third-party infrastructure, often without clear privacy guarantees.

We built Chitrax to prove that powerful file processing doesn't require server uploads. By leveraging WebAssembly, Canvas API, Web Workers, and on-device AI models, Chitrax delivers professional-grade results while keeping your files exactly where they belong: on your device.

Privacy-First Philosophy

Every tool in Chitrax processes files using your browser's local memory and compute resources. No file data ever leaves your device. When you close the browser tab, all session data is immediately cleared. We do not store, inspect, or transmit your files. Period.

Our AI-powered background removal uses neural network models that download once and cache locally in your browser. After the initial model download, even the AI features work completely offline.

How It Works

  • Image Processing: Powered by HTML5 Canvas and Web Workers for resize, compress, and format conversion tasks.
  • AI Background Removal: Uses ISNet neural network running via ONNX Runtime WebAssembly, entirely in-browser.
  • PDF Operations: Built with pdf-lib running in dedicated Web Workers for PDF creation and merging.
  • Photo Enhancement: Real-time CSS filters and SVG convolution kernels for sharpening and color correction.

About the Company

Chitrax is created and maintained by Morning Star Web, a web technology company focused on building privacy-respecting, high-performance tools for everyday users.

Our mission is to make professional-grade digital tools accessible to everyone, without compromising on privacy, speed, or user experience.

Our Values

  • Privacy First: Your files are your business. We never access, store, or transmit them.
  • No Account Required: Use any tool instantly. No sign-ups, no paywalls, no limits.
  • Performance: Optimized for speed using WebAssembly, Web Workers, and modern browser APIs.
  • Accessibility: Designed for all users across all devices and assistive technologies.

Trust & Security

Chitrax enforces strict Content Security Policy headers, validates all uploaded files using magic-byte verification (not just file extensions), sanitizes all user input against XSS, and uses HTTPS exclusively. Our file validation layer rejects spoofed or corrupted files before any processing begins.
