About this tool

URLs only allow a limited character set; everything else must be percent-encoded. The important distinction this tool makes explicit: component encoding (encodeURIComponent) escapes characters like /, ? and & — correct for a single query-string value — while full-URL encoding (encodeURI) leaves URL structure intact — correct when encoding a complete address. Using the wrong one is the classic cause of broken links and double-encoded %2520 artifacts. Decoding reverses either form.

Frequently asked questions

Component encoding vs full-URL encoding — which do I need?

Encoding a value that goes inside a query string (like a search term): component. Encoding a complete URL while keeping :// and ? working: full URL. When in doubt for a single parameter value, use component.

Why does my decoded text show %2520?

That's double encoding — a %20 was encoded again, turning % into %25. Decode twice to recover the original, and fix the pipeline that encodes twice.

Are + signs spaces?

Only in the historical form-encoding of query strings. Standard percent-encoding uses %20 for a space; this tool follows the standard and also decodes + as a space in decode mode when it appears in query-style input.
