What is Base64 & URL Encoding?

Base64 Encoding is used to translate binary structures or characters into a safe ASCII string representation. This is commonly used in HTML data URIs, basic authorization headers, or storing encryption keys.

URL Encoding (also known as Percent Encoding) converts special characters in URLs into a valid `%` format (like spaces to `%20`). This prevents query string parameters from breaking browser URLs.

Paste Encoded URL

Input your percent-encoded URL string or escaped query parameter block.

Percent-Decoding

Hexadecimal percent pairs (`%xx`) are translated back to their UTF-8 character symbols.

Get Decoded Text

Copy the readable URL structure or text payload. 100% private in-browser execution.
