Small utilities I kept rebuilding, finished once and left open for anyone.
Most of these began as a side quest inside client work — a password that had to be generated properly, an image that needed to lose 400 KB before it shipped, a component I had already written three times. Instead of leaving them in a scratch folder, they are here as finished pages.
Nothing on this page asks for an account, and wherever the work can happen on your own machine it does — the file or the text you paste never leaves the browser. The list grows whenever a project throws up something worth reusing.

Why these are free
I built most of these for myself while shipping client work. Putting them online costs me almost nothing, and someone else running into the same problem should not have to rebuild them.
Free, with no catch
No trial timer, no credit card, no locked features waiting behind a plan. If it is on this page, all of it works.
Your data stays yours
Wherever it is possible, the work happens in your browser. Nothing you paste, upload or generate is stored on a server.
Built to do one thing
Each tool solves a single problem I kept running into on client work — no dashboards to learn, no onboarding to sit through.
Still being added to
The list grows whenever a project throws up something worth reusing. Suggestions are genuinely welcome.
