Question 1

What is URL encoding?

Accepted Answer

URL encoding converts special characters (spaces, symbols, non-ASCII) into a format safe for URLs using percent-encoding. For example, a space becomes %20 and & becomes %26.

Question 2

What is Base64 encoding used for?

Accepted Answer

Base64 encoding converts binary data (images, files) into ASCII text so it can be safely transmitted over text-based protocols like HTTP and email. It increases data size by about 33%.

Question 3

How do I decode a URL?

Accepted Answer

To decode a URL, replace percent-encoded characters with their original values (e.g., %20 becomes a space). This tool decodes any URL-encoded string instantly without sending data to a server.

Question 4

What is a URL slug?

Accepted Answer

A URL slug is the readable part of a URL that identifies a specific page, typically derived from the page title with spaces replaced by hyphens and special characters removed. Good slugs are short, lowercase, and descriptive.

Question 5

How do URL query parameters work?

Accepted Answer

Query parameters appear after a ? in a URL and pass data to the server as key=value pairs separated by &. For example: example.com/search?q=cats&page=2 passes two parameters: q and page.
