URL Encoder/Decoder

What is URL Encoding?

URL encoding (also known as percent-encoding) converts special characters into a format that can be safely transmitted over the Internet. It replaces unsafe ASCII characters with a '%' followed by two hexadecimal digits. For example, a space becomes %20, and '&' becomes %26.

Why is URL Encoding Needed?

URLs can only contain a limited set of characters. URL encoding ensures data integrity when:

• •Building search queries with special characters
• •Sending parameters in API requests
• •Handling spaces, symbols, and non-ASCII characters
• •Reading encoded URLs from logs or analytics
• •Processing data instantly in your browser

How to Use

1. Select 'Encode' or 'Decode' mode
2. Enter or paste your text
3. Click the process button
4. Copy the result with one click

Pro Tips

Common encoded characters: space (%20), @ (%40), # (%23), ? (%3F), & (%26). When switching between modes, the tool automatically swaps input and output for quick round-trip testing.

Privacy & Security

All encoding and decoding is performed locally in your browser using JavaScript's built-in encodeURIComponent and decodeURIComponent functions. No data is sent to any server, ensuring complete privacy.
