Frequently Asked Questions

What is URL encoding?

URL encoding (percent encoding) is a method to encode special characters in URLs so they can be safely transmitted over the internet. Characters that are not allowed in URLs are replaced with a percent sign (%) followed by two hexadecimal digits.

When should I use URL encoding?

Use URL encoding when you need to include special characters in URLs, such as spaces, ampersands, question marks, or non-ASCII characters. This is commonly needed in query parameters, path segments, and when building URLs programmatically.

What characters need to be encoded?

Characters that need encoding include spaces, special symbols (&, ?, =, #, etc.), and non-ASCII characters. Alphanumeric characters (A-Z, a-z, 0-9) and some safe characters (-, _, ., ~) typically don't need encoding.

What's the difference between encode and decode?

Encoding converts special characters to their percent-encoded equivalents (e.g., space becomes %20). Decoding does the reverse, converting percent-encoded characters back to their original form.

Is URL encoding the same as HTML encoding?

No, they are different. URL encoding uses percent encoding (%XX), while HTML encoding uses entities (&, <, etc.). URL encoding is specifically for URLs, while HTML encoding is for HTML content.

Can I encode entire URLs?

Yes, you can encode entire URLs, but be careful not to double-encode. If a URL is already encoded, encoding it again will make it invalid. Our tool handles this automatically.
