URL Encoder & Decoder: Free Online Tool & Complete Guide

What is the URL Encoder & Decoder?

URLs can only contain a limited set of characters — spaces, quotes, ampersands and non-ASCII characters must be 'percent-encoded' (for example, a space becomes %20). A URL encoder does this automatically, while a decoder turns a percent-encoded string back into readable text.

This URL encoder and decoder is perfect for preparing query parameters, debugging malformed links and safely building redirect URLs. It supports full component encoding (encodeURIComponent) and whole-URL encoding, and it even recovers from common problems such as '+' being used as a space. All processing is done locally in your browser.

Frequently asked questions about the URL Encoder & Decoder

Here are the answers to the questions people ask most about the URL Encoder & Decoder.

• When do I need to URL-encode text? — Whenever you put free-form text into a URL — query parameters, paths or redirect targets. Characters like &, =, ? and spaces will break URLs unless encoded.
• What is the difference between encodeURI and encodeURIComponent? — encodeURI keeps characters that are legal in a full URL (like :/?#). encodeURIComponent encodes nearly everything and should be used for individual parameter values.
• Why does my URL show %20? — %20 is the percent-encoded form of a space. Some systems use '+' for spaces in query strings — this tool lets you switch between the two styles.
