Why use a URL Encoder & Decoder?
When transmitting data over the internet via URLs, certain characters (like spaces, punctuation, or non-ASCII letters) are restricted.URL Encoding (or Percent-encoding) converts these characters into a safe %xx format that web browsers and servers can correctly interpret.
This tool helps you quickly Encode (convert to a valid URL format) and Decode (convert back to readable text). If you frequently work with web APIs, pairing this with our JSON Formatter is a must for any developer's toolkit.
Frequently Asked Questions
While modern browsers often auto-encode URLs in the address bar, when writing code or making API requests programmatically, failing to encode special characters can lead to broken links or 400 Bad Request errors. It is always safest to properly encode URL parameters.
