About the project
Useful tools, built with privacy in mind
CosmoTools is an independent project created and maintained by Diego Azevedo.
Why CosmoTools exists
CosmoTools brings practical data, document, text, QR Code, image, and developer utilities together in one place. The goal is to make common tasks quick to complete without requiring an account, installing software, or sending sensitive working data to an application server when the browser can do the job locally.
How the tools are built
Each tool is implemented and reviewed as part of the same project. Pages include usage guidance, supported formats, practical examples, limitations, and privacy information where those details help users understand the result. Tools are tested as the project evolves, but important output should still be verified before it is used in production or for decisions with legal, financial, medical, or safety consequences.
Privacy by design
Most conversions and generators run directly in your browser. Unless a tool clearly explains that it needs an external service, its input and output are not uploaded to CosmoTools. See the Privacy Policy for details about local storage, analytics, technical logs, and the limited tools that contact third-party services.
