Base64 encoding turns binary data into ASCII text so it can be used in JSON, XML, URLs, or emails. It’s not encryption—it’s encoding. Common uses include embedding small images as data URIs, sending binary in APIs, and storing hashes in text fields.
A free Base64 encode/decode tool lets you paste text or Base64 and switch between the two instantly. No install, no account. For sensitive data, prefer a tool that runs in the browser so nothing is sent to a server.
Use our Base64 Encoder to encode or decode in one place. Paste input, get output—free and private.
