About PrivaDeck
A free, privacy-first toolbox built on the open web. Every file stays on your device.
Our Mission
Most online tools upload your files to a remote server before processing them. We thought that was backwards. PrivaDeck gives you a fast, free, modern alternative — every operation runs inside your browser, so your files never leave your device. No accounts, no servers, no surprises.
Privacy Without Compromise
We don't collect your file contents, file names, or anything derived from them. There is no server-side log of what you process. The site is a static export deployed to Cloudflare Pages — when you close the tab, your data is gone.
Built On
WebAssembly
FFmpeg, PDF.js, and other native libraries compiled to WebAssembly run at near-native speed inside your browser.
Canvas & Web APIs
Image cropping, resizing, and format conversion use the browser's native Canvas API for GPU-accelerated rendering.
FFmpeg.wasm
Trim, compress, and convert videos and audio entirely client-side, powered by FFmpeg compiled to WebAssembly.
pdf-lib & PDF.js
Merge, split, rotate, and edit PDFs with battle-tested libraries that run completely in the browser.
