I built SwiftFiles because I was tired of uploading sensitive documents to random servers just to merge a PDF or convert an image. The idea was simple - unify all these utility tools that process different types of files into one web-based solution.

Everything here runs 100% client-side in your browser using WebAssembly (FFmpeg.wasm, PDF-lib, etc.). No files are ever uploaded to a server. It's fast, free, and private by design.

I’m looking for technical feedback on the performance and any tools you’d like to see added next!
