About URL Encoder / Decoder

URL encoding and decoding are techniques used to represent and handle special characters in URLs.

URL encoding is the process of converting characters into a format that can be safely transmitted over the internet. This is particularly useful when the URL contains special characters, such as spaces or non-alphanumeric characters, which might be misinterpreted or cause issues during transmission.

URL decoding is the reverse process, where encoded characters in a URL are converted back to their original form.

Here's a brief explanation of how URL encoding and decoding work:

URL Encoding:

Replace Special Characters:
- Replace each special character with a percent sign % followed by two hexadecimal digits representing the ASCII code of the character.
- For example, space (' ') becomes '%20', and ampersand ('&') becomes '%26'.
Alphanumeric Characters:
- Alphanumeric characters (letters and numbers) are generally not encoded.

URL Decoding:

Identify Encoded Sequences:
- Identify sequences in the URL that start with a percent sign '%' followed by two hexadecimal digits.
Convert Back to ASCII:
- Convert these hexadecimal digits back to their ASCII representation.
Restore Special Characters:
- Replace the encoded sequences with the corresponding special characters.

Example:

Original URL:

arduino

https://example.com/search?q=url encoding&lang=en

URL Encoded:

perl

https://example.com/search?q=url%20encoding&lang=en

URL Decoded:

arduino

https://example.com/search?q=url encoding&lang=en

Tools:

You can use various online tools or programming libraries to perform URL encoding and decoding. Many programming languages provide functions or methods for this purpose. For example, in JavaScript, you can use encodeURIComponent() for encoding and decodeURIComponent() for decoding.
