Is my data safe when using these tools?
Most of our tools run entirely in your web browser using client-side JavaScript. Your passwords, files, and text are processed locally on your device and are never transmitted to our servers. For the few tools that require server-side processing (like DNS Lookup), we minimize data collection and do not store your queries.

No. All tools are available immediately without registration. You do not need to provide an email address, create a password, or sign in with any third-party service. Just open a tool and start using it.
What types of tools do you offer?
We offer PDF tools (merge, split, convert, rotate, annotate), password tools (strength checker, generator), encoding and hashing tools (Base64, MD5, SHA-256), and network tools (DNS lookup). We are continuously adding new tools to expand our collection.
