Base64 Encoder / Decoder
Encode text to Base64 or decode it back, instantly.
Base64 turns binary or text data into a plain-ASCII string that survives systems which only expect text — email bodies, JSON fields, data URIs and HTTP headers. This tool moves data in both directions: type or paste your content and read the result the moment you finish.
Common reasons to reach for it
- Embed a small image or font directly in CSS as a
data:URI. - Inspect a Base64 chunk you found in a token, cookie or config file.
- Safely pass text through a channel that mangles special characters.
Base64 is encoding, not encryption — it hides nothing, so never treat it as a way to protect secrets.
