Why We Built a Browser-Based File Converter Instead of Another Cloud Service

Short summary

The authors built a browser-based file converter to solve the privacy and performance problems inherent in cloud-based conversion services. By leveraging WebAssembly, Service Workers, and IndexedDB, file processing happens entirely locally—eliminating upload delays, network dependency, and vendor risk. They've open-sourced their implementation and welcome developer contributions for additional format support.
