URL Encoder / Decoder

Encode or decode URLs safely.

What is URL Encoder/Decoder?

URL Encoder/Decoder safely converts special characters in URLs to percent-encoded format and vice versa. It ensures characters like spaces, symbols, and non-ASCII characters are properly formatted for web transmission. This prevents broken links and ensures URLs work correctly across all browsers and systems.

Common Use Cases

  • •API Development: Encode parameters before sending in HTTP requests
  • •Query Strings: Properly format search parameters with special characters
  • •Debugging: Decode URL-encoded strings to read the actual values
  • •Data Safety: Ensure URLs don't break with spaces or special symbols

Common Use Cases

Prepare query strings for safe transmission in links and APIs.

Frequently Asked Questions

When should I URL-encode text?

Encode text whenever it includes reserved characters or spaces in query parameters or path segments.

What does percent encoding do?

It replaces reserved characters with % followed by hexadecimal values so URLs remain valid and unambiguous.

Can bad encoding break redirects or tracking?

Yes. Incorrect encoding can truncate parameters, misroute users, or produce invalid destination URLs.
