Base64 turns binary data into ASCII text so it can be safely used in URLs, JSON, XML, or emails. It's widely used for encoding images, file uploads, and API tokens. Our free Base64 encode/decode online tool works both ways—paste text or Base64 string and get instant results.
Encode and decode Base64 in one place
Paste plain text to get Base64, or paste Base64 to get the original text. No installation, no account. The live tool on this site encodes and decodes text in the browser; it does not upload files.
