Private by Design. Zero Servers.
OnlyFiles was engineered with one non-negotiable principle: your confidential documents, legal contracts, tax records, and personal photos must never leave your computer.
Our Mission & Technology
Traditional online PDF converters and image optimizers ask you to trust their servers with your most sensitive information. Every day, millions of confidential files are uploaded to third-party databases, cloud buckets, and external compute servers where they risk being retained, leaked, or exposed to breaches.
OnlyFiles eliminates this vulnerability completely. By harnessing modern browser capabilities including WebAssembly (WASM), HTML5 Canvas API, and the Web Cryptography API (W3C Standard), our suite executes 100% of its computation locally inside your device’s browser engine (V8, JavaScriptCore, Gecko).
Zero Server Uploads
Files stay strictly in your computer's RAM. No backend server ever receives a single byte of your file content.
Instant Local Processing
Bypassing cloud queues means processing completes in milliseconds without network bandwidth throttling.
Military-Grade Encryption
Tools like our Security Vault utilize AES-256-GCM and PBKDF2 cryptography calculated entirely in your browser.
Network Proof & Transparency
You can verify our privacy guarantee yourself at any time: open your browser's Developer Tools (F12), switch to the Network tab, and run any tool on OnlyFiles. You will observe that zero payload packets or file bytes are dispatched to external endpoints.
