URL Encoder

Encode and decode URLs and URI components.

About this URL Encoder

URL Encoder encodes and decodes URI components so query strings, redirects, and API parameters survive reserved characters like spaces, ampersands, and non-ASCII text. Developers build query strings; marketers debug UTM links; freelancers fix broken share URLs from clients. Paste a string, encode or decode, and copy the safe result. Encoding runs locally so unreleased campaign URLs stay private. Encode components—not entire URLs including scheme—when only a parameter value needs escaping, and decode carefully when diagnosing double-encoding bugs that turn %2520 into littered percent signs. Build query strings with a URL API in code for production; use this tool for debugging escapes. Log both raw and encoded forms when support tickets mention “broken links.”. Beware email clients that reflow long encoded URLs with line breaks.

  2. 2Choose Encode or Decode.
  3. 3Review the transformed output.
  4. 4Copy the result into your query string or docs.
  5. 5Test the full URL in a browser to confirm parsing.

Frequently asked questions

Should I encode the whole URL including https://?
Usually encode parameter values and path segments separately so the scheme and structure remain intact.
What does %20 mean?
It is an encoded space. Some forms use + for spaces in query strings depending on encoding style.
Why do I see %2520?
That often means double-encoding—a % was encoded again. Decode stepwise to repair.
Is this the same as HTML entity encoding?
No. URL encoding targets URI syntax; HTML entities target markup.
Are Unicode characters supported?
Percent-encoding can represent UTF-8 bytes so non-ASCII text can travel in URLs.
