Why encode URL values?

URLs reserve characters such as spaces, ampersands, hashes, and question marks for special purposes. Percent encoding preserves your actual data so browsers, servers, and APIs interpret it correctly.

Frequently Asked Questions

What is URL encoding? +

It replaces unsafe characters with percent-encoded byte sequences that can safely travel in a URL.

Which standard should I use? +

Use RFC 3986 for URL paths and general components. Use form encoding for application/x-www-form-urlencoded query or form data.

Why does form encoding use plus signs? +

In form encoding, a plus sign commonly represents a space. RFC 3986 instead encodes spaces as %20.

Is my input stored? +

No database persistence or conversion history is used.
