Playground

Run real compression in your browser — the same Rust core as the package, compiled to WebAssembly. Your files never leave this page: nothing is uploaded anywhere, and the result is downloaded straight from your browser.

WASM build not yet present — run the build step.
The playground needs the compiled WASM core (public/wasm/dusimagez_wasm.js), and it has not been built yet. Build it with wasm-pack build --target web crates/dusimagez-wasm (see website/public/wasm/README.md), then rebuild the site. The controls below are disabled until then — this page will not pretend to compress anything.

1. Pick an image

Image file (one file)

No file loaded yet.

No image handy? (a gradient, made in your browser — test data only).

2. Options

Engine: not loaded yet — it loads on first run.

3. Result

Honest limits: the playground runs the real v0.1.0 core, so the same limits apply — no HEIC, AVIF encode is lossy-only / 8-bit, GIF encode is first-frame only for animated input, and the whole image lives in memory. Read the formats page →
