Nothing leaves the tab
Every tool is JavaScript running locally. There is no upload step and no server to send your input to.
No account, no limits
No sign-up wall, no daily quota, and no email capture before you can use a formatter.
Links carry your input
Most tools read from the URL, so you can share a prewired link instead of pasting instructions.
