URL Encoder / Decoder

Percent-encode text for URLs, or turn %20 soup back into readable text. Two encode modes for the two real situations.

Processed in your browser — URLs and tokens never leave this page.

The characters that need encoding

CharacterEncodedWhy it breaks URLs
space%20Ends the URL in many parsers
&%26Starts a new query parameter
=%3DSeparates key from value
?%3FStarts the query string
#%23Starts the fragment — everything after is dropped from requests

Common questions

What is URL encoding?

Converting characters that aren't allowed in URLs (spaces, &, ?, non-Latin letters) into percent-codes — a space becomes %20, an ampersand %26. Without it, those characters break links and query strings.

What's the difference between the two encode buttons?

Encode component encodes everything including / ? & = — use it for a single value going into a query string. Encode full URL preserves URL structure characters — use it on a complete address that just has spaces or special characters in it.

Why does my decoded text show a ⚠ error?

A stray % not followed by two hex digits makes the encoding malformed — usually a truncated copy. Find the lone percent sign and the rest will decode.

Is what I paste sent anywhere?

No — encoding and decoding use your browser's built-in functions, on your device. URLs often contain tokens and session IDs, so that matters.
