About Encoding Tools

Encode and decode Base64 and URL-encoded strings in both directions. Handy for inspecting an encoded API payload, debugging query strings that arrive double-escaped, embedding text in a data URI, or reading what an escaped URL actually says. Each tool converts as you type and handles Unicode correctly. Input stays in your browser — nothing is uploaded.
