Opens your real Office files
Drop in a .pptx, .docx or .xlsx and it opens right away. WebDecks reads the real Office format, not a lossy copy, so your file shows up the way you built it.
An Office-file engine that runs in the browser.
WebDecks opens, edits, renders and exports PowerPoint, Word and Excel with a from-scratch WebGPU engine. Open your files free in a browser tab, embed the same engine in your product with the SDK, or let an AI agent drive real documents from code. Nothing uploads. Your files stay on your device.
- Runs in any modern browser
- No install, no account
- Files stay on your device
Made in Europe 🇪🇺
Open your Office files in a tab, edit them, and export a clean copy.
Runs entirely in your browser
No server, no download, no setup. Open a tab on Windows, Mac, Linux or a Chromebook and start working.
Export to PDF or back to Office
Turn your file into a clean, shareable PDF in one click, or save it back to .pptx, .docx or .xlsx. The export path aims to match desktop Office.
Edit text, shapes, tables and cells
Make the changes you actually need: fix a typo, move a box, swap an image, adjust a table or a cell. Light editing, made quick.
No install, no account
Nothing to download and no sign-up. It's free. Open it and go.
Your files stay on your device
Your documents open and stay in your browser. Nothing uploads to us, so your work stays yours.
One engine, three apps
WebDecks, WebSheets and WebDocs run on one engine. The same code opens presentations, spreadsheets and documents in your browser, and it's the engine you can also license or drive from your own code.

SDK · AI agents
Give your AI agent real documents to work on
Drive the same engine from a few lines of TypeScript. The WebDecks SDK loads a document, reads the true model (text, tables, cells and formulas), edits it, and exports PPTX, DOCX, XLSX or PDF. It all runs in the browser. Give your own agent the code, or connect a WebMCP client. Nothing uploads.
- Read the true document model from code: text, tables, cells, shapes and formulas
- Edit it and export to PPTX, DOCX, XLSX or PDF, through the same paths the File menu uses
- Drive it from your own TypeScript, or connect a WebMCP browser agent
Building it into your product? The SDK is free to try. Production use needs a commercial license. License WebDecks
