Why use a Client-Side Tool?
How can I process confidential files safely?
Since Mojodocs runs entirely in your web browser using WebAssembly, your sensitive data and documents never touch a public server. It is the safest way to handle medical records, legal IDs, or personal files without installing software.
Does this work without internet?
Yes. Once this page is loaded, the application logic is cached in your browser. You can disconnect from Wi-Fi and continue processing thousands of files with native performance.
