About Everyday Utilities tools
UsefulGo everyday utilities are designed to solve common digital chores right in your browser. From inspecting text differences and converting measurement units to generating cryptographically sound passwords and testing device hardware, all operations execute on your client machine with high speed and zero tracking.
Frequently asked questions
Are passwords generated by UsefulGo secure?
Yes. Our Password Generator uses the browser Web Cryptography API (`crypto.getRandomValues`). This delivers cryptographically secure randomness equivalent to native operating system password generators.
Is my text, code, or sensitive data uploaded anywhere?
No. All utilities (including Text Diff, Base64 Converter, URL Encoder, and Case Converter) run 100% client-side in your browser. Your data remains strictly on your machine.
What is the purpose of URL encoding and decoding?
URL encoding replaces reserved or unsafe characters (such as spaces, ampersands, or slashes) with percent-encoded hex sequences (e.g. `%20` for space). This ensures URLs remain valid when transmitted across web servers and browsers.
Can the Unit Converter convert between Metric and Imperial systems?
Yes. The Unit Converter converts seamlessly between Metric (SI) and US Imperial units across length, weight, area, volume, temperature, and speed.
