About SwiftTools
Free online tools that are fast, private, and need no sign-up.
SwiftTools is a collection of free online tools — calculators, counters, and generators — built for one purpose: everyday tasks should take seconds, not sign-ups.
Everything runs entirely in your browser. What you type into a tool stays on your device and disappears when you refresh the page. There is no account to create, nothing to download, and nothing to install.
What you'll find here
- Date & time tools — age calculators, date differences, business days, and more.
- Text tools — word, character, sentence and paragraph counters, case conversion, and slug makers.
- Password tools — secure generators and strength checkers.
- Percentage tools — discounts, increases, decreases, and everyday percentage math.
SwiftTools started in 2026 and keeps growing: new tools are added regularly, always free, always private. Questions or ideas? Get in touch.
