Our Mission

Too many online tools are bloated with ads, require account creation, or secretly upload your data to remote servers. ToolNest takes a different approach: every tool runs entirely in your browser. Your data never leaves your device. There are no accounts, no subscriptions, and no hidden costs.

What We Offer

Our tools span four categories to cover the most common daily tasks:

  • Developer Tools — JSON formatter, Base64 encoder, URL encoder, hash generator, UUID generator, regex tester, Markdown preview, timestamp converter, JSON to CSV converter, HTML entity encoder, and diff checker.
  • Design Tools — Color picker, CSS gradient generator, aspect ratio calculator, and favicon generator.
  • Content Tools — Word counter, Lorem Ipsum generator, QR code generator, text case converter, character map, and slug generator.
  • Security Tools — Password generator, image compressor, and JWT decoder.

Privacy First

We take your privacy seriously. All tool processing happens in your browser using client-side JavaScript. When you format JSON, generate a password, compress an image, or use any other tool, zero data is transmitted to any server. You can even verify this by using the tools with your internet connection turned off (after the initial page load). Read our full Privacy Policy for more details.

How We Stay Free

ToolNest is supported by non-intrusive display advertisements through Google AdSense. This allows us to keep all tools completely free while covering hosting and development costs. We carefully limit ad placements to avoid disrupting your experience.

Built With Modern Technology

ToolNest is built with Next.js, React, and Tailwind CSS. Our tools leverage modern browser APIs including the Web Crypto API for hash generation, the Canvas API for image processing, and the Clipboard API for seamless copy-paste workflows. The site is statically generated for maximum performance.
