How to URL-encode
  1. Paste the raw string.
  2. Choose Component for a query or path value, URI for a full URL, or Form when the receiver expects + for spaces.
  3. Copy the percent-encoded output.

What URL encoding is
Percent-encoding lets reserved characters travel inside a URI. Component is correct for query values and most path segments. URI keeps ://, ?, and similar structure so you can encode a full URL. Form matches HTML form bodies, where space becomes +.
Pair with the URL decoder or browse other encoding tools.
URL encoding is not Base64
Percent-encoding uses % and hex bytes. Base64 uses a 64-character alphabet. If the other system expects Base64, open the Base64 encoder.
URL encoding questions
Why is space %20 instead of +? 
That is the Component mode. Switch Encode as to Form if the receiver uses application/x-www-form-urlencoded.
Is this the same as Base64? 
No. Base64 is a different alphabet. Use the Base64 encoder for that.
