Credits & Technology
The magic behind FeatherPix. Making local, fast, and private image processing possible thanks to open source.
The Core Engine (Compression & WebAssembly)
This is where the real magic happens. We pay tribute to these remarkable open source projects that make ultra-fast local processing possible directly in your browser.
WebAssembly (Wasm)
The technology that enables running high-performance code (usually reserved for desktop software) directly and safely within the web browser.
jSquash Project (@jsquash)
An incredible collection of libraries that bridges the gap between JavaScript and the original, powerful C/C++ encoders.
MozJPEG
We use the MozJPEG encoder (via WebAssembly) because it currently offers the industry's best quality-to-weight ratio for standard photographs, far surpassing built-in browser encoders.
libwebp
Developed by Google's web performance team, this encoder is perfect for generating ultra-light WebP images with or without transparency, ideal for the modern web.
libavif
For next-generation AVIF compression. Backed by Netflix, Google, and Apple, it provides extreme compression for the future of web photography.
OxiPNG
A multi-threaded PNG optimizer written in Rust, ensuring a drastic reduction in complexity and file size without any visual quality loss.
User Interface & Experience (Front-end)
Web creators love to know how beautiful tools are built. Here are the foundations of our smooth and modern interface.
Next.js & React
The solid foundation of our application, allowing lightning-fast hybrid rendering and a robust architecture for a flawless user experience.
Tailwind CSS (v4)
The engine of our design system. We use the very latest generation (v4) of this utility framework to build lightning-fast, highly customized interfaces.
Radix UI / Shadcn
We rely on these primitives to guarantee a 100% accessible interface (screen readers, full keyboard navigation) combined with cutting-edge color management (P3/Oklch).
Specific Utilities & Algorithms
The small algorithmic details that make a huge difference in the quality of the final result.
heic2any
This open-source utility allows us to decode heavy Apple images (HEIC) directly client-side, ensuring your iPhone photos never transit through a server.
Lanczos3 Algorithm (Resizing)
Our resizing engine uses the Lanczos3 mathematical algorithm. It provides significantly superior detail preservation compared to basic browser resizing methods.
