When people reach for this tool

Put a value with spaces or symbols into a link

Search terms, notes and email addresses routinely contain characters that have to be escaped before they can sit in a URL.

Turn an encoded string back into readable text

Nested links from email clients and analytics tools are unreadable until the percent codes are decoded.

Repair a hand-built URL that will not parse

A single unescaped space or ampersand is enough to break a redirect; encoding each value separately is the fix.

Practical tips

  • Encode each value on its own, then join them — encoding a whole finished URL will escape the separators too.
  • Plus signs mean a space in a query string but not in a path. That difference explains most decoding surprises.

What you get

  • Safe encode/decode of any URL string
  • Handles emoji and non-ASCII characters
  • Never throws on malformed input
  • One-click swap between modes

URL Encoder / Decoder — FAQ

What is URL encoding for?
It turns characters like spaces, & and # into a safe %-encoded form so links, query strings and forms work reliably.
Why does my decoded output look the same?
If the input contains no encoded characters, decode returns it unchanged — that is expected.
What is the difference between encoding and decoding?
Encoding replaces unsafe characters with percent codes such as %20. Decoding reverses that so you get the original string back.
Should I encode a whole URL?
Usually not. Encode the individual values, then assemble the URL, otherwise the separators and the question mark get escaped along with everything else.
