Toolsped

Toolsped is a free online library of more than 800 calculators, converters and everyday tools. All tools run directly in the browser, so there is nothing to install and no sign-up or account required before use.

The site is aimed at anyone who needs a quick one-off calculation or conversion — students, office workers, freelancers and general web users — rather than at people looking for installed software.

Key capabilities:

• 800+ calculators, converters and everyday utilities in one place
• Tools run instantly in the browser
• No installation needed
• No sign-up or account required
• Free to use
