Privacy-First File Converter
A client wanted a privacy-first file converter where users never upload files to a server — video, audio, image, and PDF conversion entirely in the browser.
The platform processes conversions locally using WebAssembly. Files never leave the user's device, eliminating upload limits and privacy concerns entirely.
The Challenge
Existing online converters upload files to remote servers — slow for large files, risky for sensitive documents, and unusable offline. Desktop tools require installs and updates.
Our Solution
We engineered a WebAssembly conversion pipeline that runs fully client-side. Any file size, any format, complete privacy — works on any modern browser.
The Results
- 100% in-browser — files never uploaded
- Video, audio, image & PDF support
- No installation required
- Handles large files without server limits
