Encoding & Decoding

URL Encoder and Decoder

Encode and decode URL components without a network request.

Processed locally in your browser

Scope

Value to encode

Component mode encodes reserved characters such as /, ?, &, =, and # so the result can safely fit inside one URL part.

Result

Choose a mode and run the encoder or decoder.

Value to encode

Component mode encodes reserved characters such as /, ?, &, =, and # so the result can safely fit inside one URL part.

How to use this tool

Select Encode or Decode.
Choose Component for one URL part or Full URL for a complete address.
Enter UTF-8 text and process it locally.
Review repeated-encoding warnings before copying the result.

Examples

Component versus full URL

Encode a query value with component mode, or preserve an entire URL's separators with full URL mode.

Frequently asked questions

Does a plus sign decode to a space?

No. Percent decoding preserves literal + characters. Form-urlencoded data uses a separate convention where + may mean a space.

Will malformed input be repaired?

No. Incomplete percent escapes and invalid UTF-8 byte sequences produce a precise error without changing the input.

About this tool

Encode or decode UTF-8 URL components and complete URLs locally with clear handling for reserved separators, plus signs, existing escapes, and malformed percent sequences.
