Idea: URL Encoder / Decoder

[rach-kanc]

Tool Name

URL Encoder / Decoder

Proposed Filename

url-encoder-decoder.html

Category

JSON & API

Description

A fast, completely offline utility for developers to safely encode and decode URL strings. This tool handles percent-encoding (URL encoding) for special characters, query parameters, and entire URIs, making it effortless to convert data so it can be safely transmitted over HTTP, and decodes messy percent-encoded strings back into human-readable text.

Key Features

• Two-way conversion with dedicated "Encode" and "Decode" modes
• Supports both encodeURI (for full URLs) and encodeURIComponent (for individual query parameters)
• Real-time conversion as you type
• Instantly identifies and highlights invalid or malformed URL encodings
• 1-click copy to clipboard functionality
• Operates 100% offline directly in the browser using native JavaScript

Suggested Difficulty

Easy
