About ToolHub

ToolHub is a curated directory of 22 free online tools. Every tool runs entirely in your browser — no signup, no file uploads, no installation required.

Our Mission

We believe online tools should be simple, fast, and private. Too many "free" tools online require you to create an account, upload your files to their servers, or deal with intrusive ads and popups. We do things differently:

• Privacy first — All processing happens on your device. Your files never leave your browser.
• No signup — Use our tools immediately. No account needed.
• Free forever — All features are free with no hidden costs.
• Multi-language — Available in 10 languages: English, Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Russian, and Arabic.

The 22 Tools

Our collection includes image tools (compressor, converter, cropper, watermark, merger, GIF), developer tools (JSON formatter, Base64, URL encoder, timestamp, regex, text diff), design tools (QR code, color converter, CSS gradient), text tools (password generator, word counter), and life tools (unit converter, date calculator, PDF merger, PDF splitter, ZIP compressor).

Technology

All tools are built with Next.js, React, and Tailwind CSS. Deployed on Vercel. Each tool is a standalone project with its own subdomain, linked together through this hub.
