Free online URL encoder and decoder tools. Properly encode special characters in URLs and decode percent-encoded URLs back to readable text.
URLs can only contain certain characters. Spaces, ampersands, question marks, and non-ASCII characters all need to be "percent-encoded" to be transmitted safely. If you've ever seen a URL full of %20 and %3F — that's URL encoding at work.
Our URL Encoder and URL Decoder let you convert quickly between plain text and URL-encoded format.
When You Need URL Encoding
- Building API requests — Special characters in query parameters need encoding
- Debugging redirects — Decode a mangled URL to see the real destination
- Creating shareable links — Ensure special characters don't break your URLs
- Web scraping — Understand and reconstruct encoded URLs from page sources
Both tools work instantly — type or paste your text and the conversion happens in real time.
