About URL encoding
URL encoding (also called percent-encoding) makes text safe to drop into a web address. Spaces
become %20, an ampersand becomes %26, and so on, so your links and
query parameters never break. Decode does the reverse, turning an encoded URL back into readable
text. It all runs in your browser.
Frequently asked questions
What is URL encoding?
URL (percent) encoding replaces characters that are unsafe in a URL — like spaces, &, ? and = — with % codes, so links and query strings stay valid.
When do I need it?
Whenever you put text into a URL query parameter, such as a search term or a redirect target, encode it first so special characters don’t break the link.
Is my input uploaded?
No. Encoding and decoding happen locally in your browser.
