How It Works

All tools run entirely in your browser — no uploads, no servers, no waiting for a network round-trip.

Core technologies

WebAssembly

Near-native performance for AI inference and codec execution — no GPU required.

ONNX Runtime

Runs ISNet (background removal) model client-side with SIMD acceleration.

jSquash Codecs

MozJPEG, Oxipng, WebP, and AVIF encoders compiled to WASM.

ESRGAN

2× super-resolution model for intelligent detail reconstruction.

Canvas API

GPU-accelerated pixel manipulation for instant crop and format export.

TensorFlow.js

Powers progressive model loading and inference scheduling.

Every tool on this list processes images locally. No image data is ever sent to a server — the processing happens inside your browser tab using WebAssembly and AI models downloaded once and cached.

No GPU required

WebAssembly with SIMD instructions delivers near-native speed on any modern laptop or phone CPU.

Works offline

After the first visit, WASM modules and AI models are cached — tools keep working without an internet connection.

Open source

Built on jSquash, ONNX Runtime Web, upscaler.js, and TensorFlow.js — all battle-tested open source libraries.
