Frequently asked questions

What is URL encoding?

URL encoding (percent encoding) replaces special characters with a % sign followed by hex codes. For example, a space becomes %20. This lets URLs safely contain characters that would otherwise break them.

Component vs Full URI - which should I use?

Use Component when encoding a single value like a query parameter. Use Full URI when encoding a complete URL where you want to keep the structure (://, ?, &, =) intact.

Which characters need encoding?

Spaces, quotes, non-ASCII characters, and reserved characters like & = ? / # % all need encoding in URLs. This tool handles all of them automatically.

Is my data uploaded?

No. All encoding and decoding runs in your browser using native JavaScript. Nothing is sent anywhere.
