What It Does

Our URL Encoder/Decoder handles percent-encoding (also called URL encoding) which is essential for creating safe, valid URLs. It encodes special characters like spaces, ampersands, and equals signs into percent-encoded format (like %20 for space). The tool can encode full URLs or just specific components like query parameter values. It also decodes encoded URLs back to readable text. All encoding and decoding happens in your browser, ensuring your URLs never leave your device.

Why It's Useful

URLs can only contain certain characters safely. Special characters and spaces must be encoded to work properly in web addresses. This tool is essential for web developers building URLs with query parameters, handling user input in URLs, and working with international characters. It's crucial for API development, web scraping, and any application that constructs or parses URLs. Proper URL encoding prevents broken links and ensures compatibility across all browsers and systems.
