I built a free browser-based toolkit that processes files locally

I got tired of using online tools that require uploading files to random servers, especially for PDFs, images, and developer utilities.

So I built ArmyTool:

https://armytool.site

Everything runs directly in the browser:

- image converters

- PDF utilities

- JSON/base64 tools

- text utilities

- audio tools

Main goal:

- no uploads

- local processing

- privacy-focused

- fast/simple UI

A lot of tools use browser APIs + client-side processing instead of sending files to a backend.

Would love feedback on:

- missing tools

- UX improvements

- performance

- features developers actually want

Also curious:

What’s the one online utility you use constantly but still hate the UX for?
