Welcome to Tool Hub: Free Developer Tools That Stay in Your Browser

Tool Hub is a free collection of developer utilities designed to run in your browser. Format JSON, encode text, convert timestamps, generate QR codes, and more — without creating an account.

Open the homepage or browse all tools to get started.

Built around local processing

Everyday tools on Tool Hub are built so that your input is handled on your device:

• No need to upload paste content to a backend just to format or convert it
• Results appear right in the page as you work
• You stay in control of whatever you typed

That keeps common workflows — cleanup, conversion, quick checks — simple and private by design.

What you will find

Tool Hub covers the utilities developers reach for often:

• JSON — format, minify, CSV and TypeScript helpers (JSON Formatter)
• Encode & decode — Base64, URL encoding, hashes, JWT inspection (Base64)
• Text — counters, diffs, regex, find & replace, and more
• Formatters — JavaScript, CSS, HTML, SQL, Markdown ↔ HTML
• Generators — UUIDs, passwords, QR codes, sample data (QR Code Generator)
• Converters — timestamps, colors, units, and related helpers (Timestamp Converter)

Each tool page includes a sidebar so you can jump between related utilities quickly.

Try it

Pick a tool, paste a sample, and convert it. Tool Hub is meant to be fast to open, easy to use, and careful with your data — by keeping the work in the browser.
