ToolsRuby is a free collection of calculators, converters and file tools for everyday questions. How much is this loan going to cost each month? When is my baby due? How do I make this PDF small enough to email?
What you’ll find here
- Calculators for health, money, math, dates and pregnancy.
- Unit converters for moving between US and metric measurements.
- File tools for images and PDFs.
What we care about
- Free, with no sign-up. Open a tool and use it.
- Made for phones. Most people use our tools on a phone, so we design for that first.
- Private by design. Our calculators, image tools and PDF tools run in your browser, so your numbers and files stay on your device.
- Plain English. Each tool explains its result and how it works.
How the site is paid for
ToolsRuby is free to use. We may show ads in the future to support the site, and you still won’t pay to use a tool. If we do, we’ll keep them away from the space between a tool’s inputs and its result.

Our results are estimates for general information. They aren’t medical, financial or legal advice, so please check anything important with a qualified professional.
