URL Encoder — complete guide
Why percent-encode URLs?
URLs can only safely carry a limited character set. Spaces, unicode, and reserved characters (&, =, ?, #) must be percent-encoded (for example, space → %20) so browsers and servers parse the address correctly.
The URL Encoder on space4.dev percent-encodes text in your browser — useful for query parameters, OAuth redirects, and sharing links with special characters.
How to encode a URL or query value
Steps:
- Paste the raw string (a full URL or a single query value).
- Encode to produce a percent-encoded result.
- Use the output in href attributes, API clients, or redirect URIs.
- Decode later with the URL Decoder if you need the original text back.
Encoding tips
Encode parameter values, not entire URLs blindly, when you only need to escape a search term. Double-encoding (%25) is a common bug — encode once unless a protocol explicitly requires otherwise.
