Stop uploading sensitive documents to random servers. Convertafile leverages browser-side WebAssembly to convert your files locally. It’s lightning-fast, highly secure, and completely private.

Hey Product Hunt! 👋 I built Convertafile because I was frustrated by a common problem: having to upload sensitive documents to random third-party servers just to change a file extension. Most free converters process your data on their backend, which is a massive privacy risk and adds unnecessary upload/download latency. I wanted to build something fundamentally safer. Convertafile flips the model by running the conversion entirely locally in your browser using WebAssembly. Your files never leave your device. Here is what makes it different: 🔒 100% Private: Zero uploads. No server ever sees your files. ⚡️ Instant Speeds: Because there’s no upload/download latency, conversions start instantly. 🛠️ Serverless Edge Delivery: The app itself is served instantly via a lightweight serverless architecture, but the heavy lifting happens on your own machine. I'd love to hear your thoughts! What file formats do you find yourself converting the most? I'll be in the comments all day to answer questions and take feature requests!

Converted a 50-page PDF to Word right in the browser and it took like two seconds. Love that nothing ever left my machine.

@berkay135520 Thanks for the nice comment!

the local browser-side processing is a really thoughtful call, especially for anyone dealing with contracts or medical docs. love that there's nothing to install and it just works.
