URL encoding (percent-encoding) converts characters into a format that can be safely transmitted over the internet. Special characters like spaces, ampersands, slashes, and non-ASCII characters must be encoded to avoid breaking URLs. This is essential for web development and API integration.
Our URL encoder instantly converts text to a properly encoded URL-safe format. Spaces become %20, ampersands become %26, and all special characters are handled correctly. The tool also provides URL decoding — paste an encoded URL and see the human-readable version.
Essential for web developers, QA engineers, API integrators, and anyone working with HTTP requests. All encoding and decoding happens locally in your browser. No server calls, no data logging, complete privacy.
