The engine behind WebDecks

The public apps run on one engine we wrote from scratch. It is not a wrapper around someone else's editor, a plugin, or a server round-trip. It compiles to WebAssembly, draws every pixel on the GPU, and opens PowerPoint, Word and Excel in a browser tab. If you need that engine in your own product, you can license it.

Built from scratch for the browser

Most web apps stack up heavy libraries. WebDecks is a purpose-built engine with a tight, data-oriented core, compiled to run directly in your browser. Nothing installs, nothing phones home. It loads as a web page and runs on your machine.

We own the engine end to end, so the download stays small and the editing loop stays fast. It redraws only what changes, which keeps it smooth on modest hardware.

GPU-accelerated rendering

Your document is drawn on the graphics card, not laid out as web-page elements. WebDecks composites text, shapes and images on the GPU, which keeps scrolling, zooming and editing crisp.

Text is resolution-independent and stays sharp at any zoom. WebDecks renders fonts from their true outlines, not from pre-baked bitmaps.

Reads real Office files, exports faithfully

WebDecks reads the real .pptx, .docx and .xlsx formats and rebuilds your document: text, layout, shapes, tables and images. The same engine drives a high-fidelity PDF export that aims to match what desktop Office produces.

Licensing the engine

The engine behind WebDecks is available to license: the browser-native renderer, the SDK, and our high-fidelity PPTX-to-PDF path. Ship a real .docx, .pptx and .xlsx editor and renderer in your own product without building an engine yourself.

The public apps are the engine, dogfooded in production. It runs client-side with no backend, and the WebAssembly download is small. If you need fast, accurate Office rendering or PPTX-to-PDF inside your product, get in touch.
