Rune pro tipsPro Tips

  • Use Component mode (encodeURIComponent) when encoding values for query parameters.
  • Full URL mode (encodeURI) preserves URL structure characters like / and ? while encoding spaces and special chars.
  • Double-encoded URLs (e.g., %2520) usually mean the URL was encoded twice, decode it twice to fix.
  • Spaces can be encoded as %20 (standard) or + (form data) depending on context.

Getting the Best Results with URL Encoder / Decoder

The first step is straightforward: Paste a URL to encode or an encoded string to decode. URL Encoder / Decoder is built to accept input right away, so you spend your time on the actual task rather than navigating settings panels.

Once your input is ready, choose mode. Select Encode or Decode, and optionally enable Component mode. Results appear in real time, giving you immediate feedback before you commit to a final output.

Finally, get results. Click to process and copy the result to clipboard. The entire process from start to finish typically takes under a minute for most inputs.

Frequently Asked Questions

What people ask most about URL Encoder / Decoder

What is URL encoding?

URL encoding (percent-encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Spaces become %20, ampersands become %26, and so on.

What is the difference between encodeURI and encodeURIComponent?

encodeURI() encodes a full URL while preserving special URL characters like :, /, ?, #. encodeURIComponent() encodes everything except letters, digits, and - _ . ~ making it ideal for query parameter values.

Is my data safe?

Yes. All encoding and decoding happens entirely in your browser. No data is sent to any server.

Can I encode non-ASCII characters?

Yes. Both encodeURI and encodeURIComponent handle Unicode characters by converting them to UTF-8 byte sequences and percent-encoding each byte.

Why do I need to encode URLs?

URLs can only contain certain ASCII characters. Special characters, spaces, and non-ASCII characters must be percent-encoded to be valid in a URL.

What does %20 mean?

%20 is the URL encoding for a space character. The % sign followed by two hexadecimal digits represents a single encoded character.

Is URL Encoder / Decoder free?

Yes! URL Encoder / Decoder is 100% free with no limits, no sign-up, and no ads. Use it as many times as you need.

What is double encoding and how do I fix it?

Double encoding happens when an already-encoded URL is encoded again, turning %20 into %2520. Simply decode the string twice to restore the original text.
