Encode or decode URL text
What does a URL encoder and decoder do?
Spaces, non-Latin text, emoji and reserved characters must be represented safely inside URL components. This tool transforms a single value or URL fragment and refuses malformed percent sequences during decoding instead of producing a misleading guess.
Transformation logic
Encoding uses the browser-native encodeURIComponent function, which represents unsafe component characters as UTF-8 percent sequences. Decoding uses decodeURIComponent and returns an explicit error when the sequence cannot be decoded safely.
Campaign-copy example
Encoding “夏季 sale & CTA” returns %E5%A4%8F%E5%AD%A3%20sale%20%26%20CTA, which can be used as one URL-parameter value. Decode mode restores the same readable text.
How to use
- Choose whether to encode plain text or decode percent-encoded text.
- Paste a value or URL component, then run the transformation.
- Copy the result into the intended URL field; use a URL builder for a full campaign link.
Frequently asked questions
Does this encode a whole URL?
It is intended for text and URL components. Encoding a whole URL would also encode https, slashes and question marks; use the UTM Builder for complete campaign links.
Why can’t some values be decoded?
Incomplete percent escapes and invalid UTF-8 have no reliable interpretation, so the tool reports the issue rather than guessing at a result.
Are spaces encoded as plus signs?
This component tool encodes spaces as %20. Form-style query-string plus handling belongs to the URL builder that constructs the full URL.
