🔐 Developer & Code Tools

Welcome to the Developer & Code Tools section of MultiTool. This collection is crafted for developers and coders who want to speed up their workflow with quick and reliable utilities. Whether you want to format your JSON data, minify JavaScript and CSS, test regular expressions, or decode JWT tokens, these tools help you do it all without leaving your browser.

JSON Formatter / Validator


      

Explanation: JSON Formatter / Validator helps you quickly beautify and validate JSON data. JSON (JavaScript Object Notation) is a widely-used data interchange format. This tool ensures your JSON is correctly structured and easy to read, which is essential for debugging APIs, configuring files, and sharing data between systems. Validating JSON prevents syntax errors that can break your applications.

JavaScript Minifier / Beautifier


      

Explanation: This tool lets you either minify or beautify JavaScript code. Minification removes unnecessary spaces, comments, and newlines to reduce file size, improving load times in web apps. Beautifying formats the code for better readability and easier debugging. Both features help streamline your development and production processes.

HTML Formatter / Beautifier


      

Explanation: This tool beautifies your HTML code, making it clean, properly indented, and easier to understand. Well-formatted HTML aids in faster debugging, maintenance, and collaboration. It's especially useful when working with legacy code or auto-generated HTML that lacks proper structure.

CSS Minifier / Beautifier


      

Explanation: Similar to JavaScript, this tool helps compress your CSS to minimize file sizes for better website performance, or beautify it for readability. Minified CSS reduces bandwidth usage and speeds up page loads, while beautified CSS is easier to edit and maintain.

URL Encoder / Decoder

Explanation: URLs often contain characters that are not safe for transmission over the internet. URL encoding converts these characters into a format that browsers can handle. Decoding reverses this process. This tool is essential for web developers working with query parameters, forms, or APIs to ensure data integrity.

Base64 Encode / Decode


      

Explanation: Base64 encoding is a way to represent binary data (like images or files) in ASCII text format. It is commonly used in email, data storage, and web data transmission. This tool allows you to convert plain text to base64 and vice versa, useful for debugging and embedding data safely in text-based formats.

Regex Tester

Explanation: Regular expressions (regex) are powerful patterns for matching text. This tool helps developers build and test regex patterns quickly by showing matching results in real-time. Regex is widely used for input validation, searching, and text manipulation.

JWT Decoder


      

Explanation: JSON Web Tokens (JWT) are widely used for secure transmission of information between parties. This decoder helps you inspect the contents of JWTs by decoding their header, payload, and signature. It's useful for developers working with authentication and API security to debug tokens and ensure they contain correct data.

QR Code Generator

Explanation: QR Codes are 2D barcodes widely used for sharing links, contact info, or any text quickly with smartphones. This tool generates a QR code from your input text or URL which you can scan or embed in your materials. It's essential for marketing, product labeling, and event management.

HTTP Headers Checker


      

Explanation: HTTP headers carry metadata between client and server, including content types, caching policies, and security settings. This tool fetches and displays headers for any URL, aiding developers and security experts to analyze and debug web responses and ensure optimal configuration.
