A client-side developer utility for percent-encoding URLs, decoding query parameters, and converting text or data strings to Base64 format.
Convert reserved characters, spaces, and symbols into browser-safe percent-encoded ASCII representations.
Transform raw string payloads into ASCII strings for safe transmission across HTTP headers, APIs, and databases.
All encoding routines execute locally inside your web browser with zero server uploads.
URLs are restricted to a limited set of unreserved ASCII characters. Unsafe characters are replaced with a percent sign (%) followed by two hexadecimal digits.
Base64 encoding represents binary or text data in an ASCII string format using a 64-character alphabet to transmit data safely through APIs and HTTP headers.
Paste the encoded URL string into the textarea above and click URL Decode.
No. Base64 is an encoding scheme, not encryption.
