Frequently asked questions

What encoding formats are supported?

URL encoding and decoding, HTML entity encoding and decoding, and Base64 text encoding are available.

What is URL encoding used for?

URL encoding converts special characters in URLs to percent-encoded form so they can be safely transmitted in HTTP requests. For example, a space becomes %20, and an ampersand becomes %26.

What are HTML entities?

HTML entities are codes that represent special characters in HTML. For example, the less-than sign becomes < and the greater-than sign becomes >, preventing the browser from interpreting them as HTML tags.

Is this the same as the developer Base64 tool?

Yes, the Base64 text encoding here is equivalent. This tool is in the Text Tools section for accessibility. Both encode and decode Base64 text strings.

Does it work offline?

Yes.

Why would I need to decode a URL-encoded string?

Debugging API requests, reading encoded query parameters, and analyzing redirect URLs often require decoding URL-encoded strings to see the original values.
