About Nimble Toolbox

Nimble Toolbox is a small collection of 30 everyday utilities: converting an image, tidying a JSON payload, counting the words in a draft. Things you usually need once and in a hurry, and should not have to install anything for.

Everything runs in your browser

Most tools like these upload your file to a server, do the work there, and hand back a download link. That means your holiday photos and your unpublished draft pass through somebody else's machine on the way.

Nothing here works that way. Every tool on this site uses APIs already built into your browser, so your files never leave your device. Disconnect from the internet once the page has loaded and the tools carry on working, which is an easy way to check the claim for yourself.

What it costs

Nothing, and there is no account to create. The site is funded by advertising, so you may see an ad underneath a tool. Never above it, and never in a popup. You should not have to hunt for the button you came here to press.
