Your Files Remain Your Property.
Unlike generic web utilities that upload your sensitive documents to external AI vendors and third-party APIs, Toolora was engineered from the ground up to protect your privacy.
Browser-Side Execution
Over 85% of our utilities execute entirely inside your web browser using HTML5 Canvas, WebAssembly, and local JavaScript libraries. Your files never even leave your device.
10-Minute Auto-Purge
For operations requiring server processing, files are isolated in ephemeral directories with unique cryptographic tokens and permanently scrubbed from disk after 10 minutes.
Zero Third-Party APIs
We never route documents to external conversion services, OpenAI, Cloudinary, or remote servers. All processors run on our standalone Node.js server or client machine.
