About ToolLineup

ToolLineup is a collection of 271 small, fast tools for the jobs that come up every day — editing a PDF, resizing an image, converting a file, checking a number, formatting some data. Everything runs in your browser: no signup, no rate limits, and nothing you open is sent to a server.

Why another utility site?

Most "format JSON online" pages are slow to load and quietly upload your data to a backend. ToolLineup is designed to be the opposite: static, fast, and private, with nothing you open sent to a server.

How it works

Every tool is a lightweight page that does all of its work directly in your browser. The editors give you line numbers and collapsible sections so it is easy to scan large files. Time-zone tools use your device’s built-in time-zone information, and password and hash generators use your browser’s built-in cryptographic random source. Nothing you paste is uploaded — the tools continue to work even without a network connection.
