How Client-Side Processing Protects Your Files
Unlike traditional web tools that upload your sensitive documents to remote cloud servers, ElevenTools processes everything directly inside your browser.
Zero Uploads
Your files stay strictly on your laptop or phone. No network payload is ever transmitted containing your documents.
Browser Engine
We compile open-source engines (`pdf-lib`, WebAssembly, Canvas API) directly to client JavaScript runtimes.
Instant Execution
Without file upload or download latency, conversions finish near-instantly regardless of your connection speed.
Why Traditional Web Tools Are a Privacy Risk
When you use online file converters or PDF tools like Smallpdf or iLovePDF, your files travel over the Internet to third-party cloud servers. These servers process your documents, temporarily store them in cloud buckets, and log metadata.
Even if services promise deletion after 1 hour, your data is exposed to potential cloud leaks, server breaches, and employee access.
The ElevenTools Difference: Architecturally Private
ElevenTools doesn't just promise privacy in a policy document — we enforce it through technical architecture:
- PDF Operations: Merged and compressed via `pdf-lib` running in local browser JavaScript.
- Image Compression: Rendered onto an HTML5 Canvas and re-encoded locally to WebP or JPEG.
- Hashing & Cryptography: Computed via the browser's native Web Crypto API (`crypto.subtle`).
- Screen Recording: Captured directly via the browser's native `MediaRecorder` API.
