Hey folks,

As someone who’s a bit paranoid about privacy, I’ve always found it unsettling how many tools ask you to upload your files to random servers — even for something as basic as removing metadata.

So I built PrivMeta — a lightweight, open-source browser app that strips metadata from documents, images, and PDFs entirely on your device.

  • Works completely in-browser — your files never leave your computer
  • You can even turn off your Wi-Fi while using it
  • It’s free and open source (Here’s the repo)

It’s meant to be a super-simple privacy tool. In the future, I’m thinking of making more tools like this — maybe file converters, PDF redaction, that kind of thing — all running locally, with zero server-side processing.

I’d love to hear your thoughts. Are there any features you’d find useful in something like this? Or things you’d expect but don’t see?
