How to use it
A clear, quick workflow
- Choose Encode or Decode.
- Use URL component for a query value or path segment; use Whole URL to preserve URL structure delimiters.
- Type or paste the input, then copy the live output or swap direction.
URL Encoder & Decoder
Encode or decode URL components and whole URLs without corrupting Unicode.
URL component mode also encodes delimiters such as /, ?, &, and =.
Start typing to convert.
Example
Component encoding turns “İstanbul + kahve” into %C4%B0stanbul%20%2B%20kahve, while whole-URL mode preserves /, ?, &, and = delimiters.
Limits and behavior
Input is limited to 1,000,000 JavaScript characters. A plus sign is treated as a literal plus, not as an HTML form-space shortcut. Malformed escapes and invalid UTF-8 are rejected without replacement.
FAQ
Which mode should I use?
Use component mode for one query value, key, or path segment. Use whole-URL mode only when the input is an entire URL whose separators must remain readable.
