What this site is
WonderNudge Tools is a collection of free, single-purpose web tools for developers, writers, students and everyday users — things like a JSON formatter, QR code generator, word counter, image compressor, regex tester and a handful of calculators. Every tool is free to use, with no sign-up and no account.
The tools are built and maintained by WonderNudge, an independent product studio based in India. This site is one part of the wider WonderNudge platform at wondernudge.in.
Why we built it
Most online utilities are slow, cluttered, ask you to register, or upload your files to a server for no good reason. We wanted the opposite: quick tools that do one job well, load fast on a phone, and respect your data.
How the tools work
For full detail on what data is and is not collected, read the Privacy Policy.
What you will find here
Our tools are grouped into three categories:
- Build – code, web and developer tools such as JSON Formatter, Base64 Encoder, JWT Decoder, Text Diff, Markdown Editor, Code Playground and CSS Gradient Generator.
- Create – writing, image and content tools such as Word Counter, Text Case Converter, Readability Checker, Image Compressor, Image Resizer and the YouTube Thumbnail Downloader and Tag Extractor.
- Learn – practice, productivity and everyday calculators such as Typing Speed Test, Regex Tester, Age Calculator, Percentage Calculator and FD Interest Calculator.
Browse everything on the home page. We add new tools regularly.
How the site is funded
The tools are free. To cover hosting and development time we display advertising, including ads served by Google AdSense, and we may add other forms of advertising in future. Ads are always separated from tool functionality, and we do not let advertising decide what a tool does or what result it gives you. See the Privacy Policy for how advertising cookies work and how to control them.
Accuracy and quality
We test our tools in real browsers and fix problems when they are reported. Still, software has bugs, and calculators in particular give estimates. Please read the Disclaimer before relying on any result for something important such as a financial decision.
