Tool usage guide
The URL Encoder/Decoder is a straightforward utility designed to convert special characters into a URL-safe format or revert encoded strings back to their original readable text.
Background
A developer needs to pass a search query containing spaces and symbols through a URL.
Problem
Raw text like 'search term & filter' causes URL errors.
How to use
Enter 'search term & filter' into the input, select 'Encode', and copy the result.
Outcome
The tool outputs 'search%20term%20%26%20filter', which is safe for browser use.
Background
An analyst is reviewing API logs and sees a parameter string that is difficult to read.
Problem
The string 'user%20name%3Dadmin' is not human-readable.
How to use
Paste 'user%20name%3Dadmin' into the input, select 'Decode', and view the result.
Outcome
The tool converts the string back to 'user name=admin'.
URL encoding converts characters that are not allowed in a URL into a format using the '%' symbol followed by the character's hexadecimal value.
Encoding ensures that special characters like spaces, symbols, or non-ASCII characters do not break the URL structure or cause errors during transmission.
You can decode any string that follows standard percent-encoding rules. If the string is not properly encoded, the output may remain unchanged.
Yes, all processing happens locally in your browser, ensuring your data is not sent to any external server.
This tool is designed for single-string processing to ensure accuracy and simplicity.
