URL Encode / Decode
Secure tool for converting URLs and query parameters into a format safe for transmission across the internet.
Frequently Asked Questions
What is URL encoding used for?
It is used to safely transmit query strings, special symbols, and non-ASCII characters across HTTP requests without breaking server-side parsing or URI specifications.
How does percent-encoding work?
Unsafe characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character’s ASCII code (for example, a space becomes %20 or +).
Is my data secure when using this tool?
Yes, 100% secure. All conversions happen locally in your web browser. No text or URLs are ever transmitted to or stored on external servers.
What is the difference between encode and decode?
Encoding turns plain text into percent-encoded URI strings, while decoding converts encoded URL strings back into readable plain text.
Understanding URL Encoding (Percent-Encoding)
URL encoding is the process of translating characters into a format that can be safely transmitted over the Internet. Characters that have special meanings in URLs (such as ?, &, /, and spaces) must be converted into their respective percent-encoded hexadecimal values.
Our online encoder and decoder tool processes your text instantly in your browser. Because everything runs client-side using JavaScript, your sensitive links and query parameters remain completely private and secure.
