What is the URL Encoder/Decoder?
Encode or decode URLs for proper formatting, safe transmission, and debugging URL parameter issues.
The URL Encoder/Decoder converts text to and from URL-safe format (percent-encoding). URLs can only contain certain ASCII characters - spaces, special characters, and non-ASCII characters must be encoded. This tool handles encoding for query parameters, decoding tracking URLs, and debugging URL formatting issues. Essential for developers working with APIs, marketers managing tracking parameters, and SEO professionals analyzing crawl logs.
