Free Online URL Encoder & Decoder
The URL Encode–Decode tool lets you convert text to a safe, URL-friendly format and decode encoded URLs back into readable text. Encoding is essential when URLs contain characters like spaces, symbols, emojis, or non-ASCII characters. This tool performs accurate encoding using modern standards, ensuring that your URLs work correctly in browsers, APIs, and web applications.
URL encoding replaces unsafe characters with percent-encoded values such as %20 for spaces or %2F for “/”. This prevents errors in forms, query strings, and API calls. Similarly, decoding converts encoded URLs back to human-readable form, making debugging and web development easier. The tool also includes an option to encode spaces as “+”, a format used in legacy systems, search engines, and some form submissions.
Whether you're a developer working on web requests, a marketer checking UTM links, a student learning URL structure, or a casual user decoding a confusing encoded link, this tool offers a fast and private way to handle URL encoding right inside your browser. Nothing is uploaded to any server, making it safe for handling sensitive or confidential URL data.
