❓ Frequently Asked Questions
Everything you need to know about URL encoding and decoding
What is URL encoding?
URL encoding (also called percent encoding) is a mechanism to encode information in URLs. Special characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code. For example, a space becomes %20.
When should I use encodeURIComponent vs encodeURI?
encodeURIComponent: Use for encoding individual URL components like query parameters. It encodes all special characters including /, ?, :, @, &, =, +, $, and #.
encodeURI: Use for encoding complete URLs. It preserves URL structure characters like /, ?, :, @, &, =, +, $, and # but encodes other special characters.
What characters need to be URL encoded?
Characters that need encoding include: spaces, quotes ("), hash (#), percent (%), curly braces (), vertical bar (|), backslash (\), caret (^), tilde (~), square brackets ([]), grave accent (`), and non-ASCII characters like Chinese, Arabic, or emoji.
What is multiple decoding?
Multiple decoding repeatedly decodes a string until no more changes occur. This is useful when dealing with double or triple encoded URLs, where %2520 becomes %20, which then becomes a space. Enable this option when you suspect multiple layers of encoding.
Is my data secure when using this tool?
Yes! All encoding and decoding happens directly in your browser using JavaScript. Your data is never sent to our servers or stored anywhere. The tool works completely offline once the page is loaded.
