Frequently asked questions
Questions about URL Encoder & Decoder
What is percent encoding?
Percent encoding represents certain characters using a percent sign followed by their hexadecimal byte value. For example, a space is commonly represented as %20.
What is the difference between encodeURI and encodeURIComponent?
encodeURI is intended for complete URLs and preserves structural characters such as slashes and question marks. encodeURIComponent is intended for individual values and encodes more characters.
Why does decoding sometimes fail?
Decoding fails when the input contains incomplete or invalid percent-encoded sequences, such as a percent sign that is not followed by two hexadecimal characters.
Is URL encoding encryption?
No. URL encoding only transforms data into a URL-safe representation. It does not provide confidentiality or security.
