Convert URLs and query parameters into percent-encoded RFC 3986 format or decode percent-encoded links back to plain text instantly online.
URL Component Encoder & Decoder
Safely convert query parameters, special symbols, and characters into percent-encoded Web URL specifications.
What is a URL Encoder / Decoder?
A URL Encoder / Decoder translates special characters inside Uniform Resource Locators (URLs) into RFC 3986 compliant percent-encoded strings (e.g., converting spaces into `%20` or `+`). This prevents broken web parameter requests and guarantees correct server parameter handling across web
browsers.
How to Use the URL Encoder / Decoder
Input String: Enter raw URLs, string parameters, or percent-encoded links into the input field.
Select Action: Click "Encode URL" to convert unsafe characters into percent-encoding, or "Decode URL" to reveal the original readable text.
Copy Result: Click "Copy Output URL" to copy the converted string directly to your clipboard.
Frequently Asked Questions (FAQ)
Why do spaces convert into %20 or + in URLs?
URLs cannot contain literal whitespace characters. Standard web protocols require spaces to be escaped as `%20` or converted to `+` in URL query strings.
