Escape and unescape URL query strings safely in your browser. Free developer utility.
Key Capabilities
What is URL encoding?
URL encoding (percent-encoding) converts special characters like spaces, ampersands, and question marks into %XX format for safe inclusion in URLs. For example, spaces become %20, & becomes %26. This ensures URLs work correctly across all browsers and servers.
Who uses this tool professionally?
Frontend developers encode query parameters for API requests. QA engineers decode encoded URLs in error logs for debugging. SEO specialists decode URL-encoded slugs to verify proper page targeting and crawlability.
Does it handle international characters?
Yes. The tool properly encodes and decodes UTF-8 characters including Chinese, Arabic, Hindi, and emoji. International characters are encoded using standard percent-encoding of their UTF-8 byte representation.
