URL Encoder & Decoder

Encode strings to safe URL components, and decode back.

Input String

Encoding query parameters before appending them to a URL to ensure special characters don't break the link.
Decoding messy, percent-encoded URLs (e.g., copied from a browser address bar) into readable text.
Preparing data to be safely sent via application/x-www-form-urlencoded forms.

URL encoding converts spaces into '%20' or '+' so they can be safely transmitted over HTTP.
Always encode user input if it's being used as a query parameter to prevent URL injection attacks.

Characters that are not alphanumeric or specific safe symbols (like - _ . !) get replaced with a '%' followed by their hex value.

There is no strict limit in this tool, but remember that actual web browsers have length limits for URLs (typically around 2048 characters).
