About SwiftMultiTool

SwiftMultiTool is a collection of more than 50 free online tools, converters and calculators built to save you time. Every tool runs instantly in your browser, with no sign-up, no installation and no cost.

Our guiding principle is privacy first. Most tools process data entirely client-side, meaning your text, files and inputs never leave your device. There is nothing to install and no account to create.

The site is maintained by a small editorial and engineering team. We also publish a blog of in-depth guides on the everyday problems these tools solve — from word counts and password security to time zones, percentages and data formats.
