URL converter
Encode or decode a text to be used in URLs.
In short
URL-encode or decode strings to make them safe for use in URLs.
What Is URL Encoding?
URL encoding converts characters that are not allowed in URLs — such as spaces, punctuation, and non-ASCII characters — into a percent-encoded format (e.g. a space becomes %20).
URL decoding reverses this process, converting percent-encoded strings back to their original characters.
When to Encode or Decode
Encoding is needed when building URLs that include user-supplied input, special characters, or non-ASCII text. Unencoded special characters in a URL can break the structure of the link.
Decoding is useful when reading URL-encoded strings from logs, query parameters, or API responses.
Best For
- Developers encoding query string values for safe URL inclusion
- Marketers decoding URL-encoded tracking parameters
- SEO teams inspecting encoded URL parameters in log files
- Engineers building and debugging API request URLs
Limitations of this tool
- The tool encodes or decodes the entire input — partial or selective encoding of specific characters is not supported.
Frequently asked questions
- What characters are percent-encoded?
- Any character outside the unreserved set (letters, digits, - _ . ~) is percent-encoded. Spaces become %20, ampersands become %26, and so on.
- What is the difference between %20 and + for spaces?
- %20 is the standard percent-encoding for a space in a URL. The + symbol is used specifically in application/x-www-form-urlencoded query strings and is decoded as a space only in that context.
- Does encoding affect SEO?
- Search engines handle URL-encoded characters correctly. However, URLs with unnecessary encoding are harder to read. Use clean, human-readable URLs where possible.
