Questions people ask first
Are the tools really free?
Yes. Every tool is free with no account, no limits and no watermark.
Is my text sent to a server?
Case, text, font, code and calculator tools run entirely in your browser. IP and DNS lookups send only the address or domain you type to public services such as Cloudflare DNS and ipwho.is.
Which tools are available?
There are 183 tools across case conversion, text cleanup, Unicode fonts, code and data formats, IP and DNS lookups, and random generators.
Can I use the results anywhere?
Yes. Copy the output and paste it into documents, code, DNS panels, social profiles or chat apps.
Do I need an account?
No. There is no sign-up, login or download. Open a tool and use it.
Do the tools work on my phone?
Yes. Every page is responsive and works in modern mobile and desktop browsers.
How accurate are the IP and DNS lookups?
DNS answers come straight from public resolvers. IP location is an estimate, usually right at country and city level.
