When should I choose Component?

Use it for query values, path segments or text. It encodes delimiters that Full URL mode preserves as structure.

Why can a space be + or %20?

General percent encoding uses %20, while form encoding often uses +. The decoder makes that conversion optional.

How is Unicode encoded?

Characters become UTF-8 bytes before percent escapes are produced, so one character can create several sequences.

Will the tool open entered URLs?

No. Values remain inert text; no navigation, request or active rendering occurs.

Frequently asked questions

About URL Encoder & Decoder

Percent encoding has two jobs: protecting one value and preserving a complete URL's grammar. Component mode escapes separators, while Full URL mode retains delimiters such as slashes and ampersands. Both operate on Unicode through UTF-8.

Decoding rejects malformed hexadecimal or invalid UTF-8 instead of returning corrupted text. Plus-to-space conversion is opt-in, and results are never fetched or interpreted as links.
