A small collection of free tools I built myself, one at a time. No sign-up, no login — just open the page and use it. I add new ones whenever I run into something in daily life or work that could use a tiny tool of its own.

I build and maintain these tools on my own, and keep them free for everyone. If one of them helped you, a coffee goes a long way toward keeping me building more.
