Converters
Convert files, units, time and text. Files stay on your device wherever the browser can do the job. · 134 tools
Converters turn one thing into another without changing its meaning: kilometres into miles, 14:00 into 2 PM, a decimal into a fraction, plain text into Morse code. Each converter is a single page with the conversion up front and a short explanation of how it works underneath.
Unit and text conversions happen instantly in your browser. Nothing is uploaded and there is nothing to install.
