A 100% local and private PDF & presentation manager. Upload, organize, tag, and preview your decks directly in the browser — no cloud, no sign-up, no tracking.
DeckStack is a privacy-first presentation and PDF manager that runs entirely in your browser. No cloud uploads, no account creation, no server-side processing. Every file stays on your machine, stored locally using IndexedDB.
Presentation files pile up fast — pitch decks, training materials, conference slides, client proposals. Most tools want you to upload everything to the cloud. DeckStack takes the opposite approach: your files never leave your browser.
Drop PDF and PPTX files directly into the browser. Files are stored locally using IndexedDB, so they persist across sessions without ever touching a server.
Organize decks with custom tags — by client, topic, project, or whatever system works for you. Filter instantly to find the right deck when you need it.
Preview your PDFs and presentations without opening a separate app. Quick, lightweight, and always available.
Zero tracking. Zero analytics. Zero server calls. DeckStack is a fully client-side application. Your files are yours — period.
DeckStack is built as a single-page application that leverages modern browser APIs:
No backend. No database. No authentication. The entire application runs in the browser tab.
DeckStack is live and free to use at deck-stack.jagodana.com. Drop in a PDF and see how it works — nothing to install, nothing to sign up for.
The client needed a robust productivity tool solution that could scale with their growing user base while maintaining a seamless user experience across all devices.
We built a modern application using PDF Viewer and Presentations, focusing on performance, accessibility, and a delightful user experience.
