URL Encoder

Percent-encode or decode URLs and query values in this tab. Pasted content never leaves this device.

Processed in your browser

Conversion runs in this browser. We do not send the pasted text.

Characters: 0

Advanced options
Encoding mode

Component matches encodeURIComponent and encodes &, =, ?. Full URI matches encodeURI and keeps structural delimiters.

On encode, use + instead of %20. Decode treats both + and %20 as space.

Paste text, then encode or decode.

The converted text will appear here.

Features

Encode

Percent-encode text with encodeURIComponent-style rules for query values.

Decode

Decode percent-encoding. Plus signs can be treated as spaces.

Component and full URI

Switch to encodeURI-style Full URI mode under Advanced when you need structural delimiters kept.

Stays in the browser

Conversion runs on this device. Pasted text is not uploaded.

How to use

  1. Paste the text to encode, or the percent-encoded string to decode.
  2. Choose Encode or Decode. Under Advanced, pick Component vs Full URI, or + for spaces if needed.
  3. Check the result, then copy if you need it.

FAQ

Is pasted text uploaded?
No. Encode and decode run in this browser. The document body is not sent.
What is the difference between Component and Full URI?
Component (encodeURIComponent) encodes &, =, ? and is correct for single query values. Full URI (encodeURI) keeps structural delimiters for a whole URL.
What happens on empty or invalid encoding?
Empty input asks for content. Invalid percent sequences show a clear error, not a blank page.
Is it free? Do I need an account?
Yes, it is free. No account is required to encode, decode, or copy.
