URL Encoder / Decoder FAQ

What is URL encoding?

URL encoding (also called percent-encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Special characters are replaced with % followed by their hexadecimal code.

Why do URLs need to be encoded?

URLs can only contain certain characters from the ASCII set. Special characters like spaces, ampersands, and non-ASCII characters must be encoded to ensure URLs are transmitted correctly across different systems.

What characters are encoded in URLs?

Characters that are encoded include spaces (to %20 or +), ampersand (&), equals (=), question mark (?), hash (#), and all non-ASCII characters. Letters, numbers, and characters like - _ . ~ are not encoded.

What's the difference between encoding and encrypting URLs?

URL encoding makes URLs transmission-safe but doesn't provide security. URL encryption protects data from being read. This tool performs encoding/decoding, not encryption.

Can I encode entire URLs or just parts?

You can encode entire URLs or just specific parts like query strings or path segments. The tool handles both cases and preserves the URL structure where appropriate.

Is my URL data secure?

Yes, all URL encoding and decoding happens entirely in your browser. Your URLs never leave your device or get sent to any server.
