Frequently Asked Questions
What is URL encoding?
URL encoding converts characters that cannot be used in URLs (spaces, non-ASCII characters, special symbols) into % followed by their hexadecimal code. For example, a space becomes %20.
When should I use this tool?
Use it for web form data submission, API request parameters, sharing URLs with non-ASCII characters, sending URLs via email, and debugging web applications.
What's the difference between encode and decode?
Encoding converts special characters to % format, while decoding reverses this process. Example: "hello world" → encode → "hello%20world" → decode → "hello world"
Is it secure to use?
Yes, all processing happens entirely in your browser. Your URLs and text are never transmitted to any external server.
Can it handle long URLs?
Yes, it can process URLs with thousands of characters without issues, limited only by your browser's memory capacity.
