URL Encoder and Decoder
Encode and decode URL strings online. Free percent-encoding tool for query parameters, slugs, and full URLs.
Frequently asked questions
What is the difference between encodeURI and encodeURIComponent?
encodeURI is for full URLs and keeps characters like / and ? intact. encodeURIComponent encodes every reserved character and is meant for query values.
When should I URL-encode text?
Encode user input before placing it in query strings, form fields, or API requests so spaces and special characters do not break the URL.
Why did decoding fail?
The input may contain invalid percent sequences (like a lone %). Fix or remove malformed escapes and try again.
