About URL Encoder
URLs may only contain certain characters, so spaces, ampersands and non-Latin text have to be percent-encoded. Encoding and decoding lets you build links that survive and read ones that arrived mangled.
How to use it
- Paste your URL or parameter value.
- Encode or decode it.
- Copy the result.
Worth knowing
Encode the values inside a query string, not the whole URL — encoding the separators turns a working link into a single meaningless string.
Common questions
- Why is a space %20 sometimes and + others?
- Both appear: %20 in paths, and + in form-encoded query strings. Context decides which is correct.
- What does double-encoding look like?
- %2520 rather than %20 — a percent sign that has itself been encoded. It usually means something encoded the URL twice.
