About Private Toolbox

Our Mission

Private Toolbox exists because your files belong to you. Every online tool that asks you to upload a file creates a copy on someone else's server. We built the alternative: 100+ tools that run entirely in your browser.

Why We're Different

• 100% On-Device Processing - Your files never leave your device. We use WebAssembly and browser APIs to process everything locally.
• No Accounts Required - No sign-up, no email, no tracking of your file contents. Just open and use.
• Works Offline - Install as a PWA and use all tools without an internet connection.
• Open Technology - We use trusted open-source libraries like FFmpeg, pdf-lib, Tesseract.js, and Whisper AI.

The Technology

Private Toolbox is built with modern web technologies that enable powerful processing directly in your browser:

• WebAssembly (WASM) - Runs FFmpeg for video/audio and Tesseract for OCR
• Web Crypto API - Provides bank-grade AES-256 encryption
• Transformers.js - Runs AI models like Whisper locally
• PDF-lib - Manipulates PDFs without server round-trips

Local Storage & Cache

Private Toolbox caches large assets (like FFmpeg) locally for faster loading and offline support. Manage your storage here:

Who Made This?

Private Toolbox is an independent project built by developers who believe privacy should be the default, not a premium feature. We've combined years of experience in web development, security, and user experience to create tools that respect your data.

Our Commitment

• ✅ Privacy by design - Files never leave your device, guaranteed by architecture
• ✅ No file uploads - This is a technical guarantee, not just a promise
• ✅ Transparent analytics - We track page views, not your files
• ✅ Regular updates - New tools and improvements added regularly
