About KeptTools
A small set of free tools for formatting, encoding, and everyday image work. Each one has its own page, and the work stays in your browser.
01
No account
Open a tool and use it. There is nothing to sign up for, and nothing is saved to a profile.
02
On this device
Text, tokens, and images are handled in the page. KeptTools does not take a copy of what you paste or drop in.
03
One job each
Every page says what the tool does and where it stops, so you can tell if it fits the task.
