Base64 Encoder/Decoder

What is a Base64 Encoder/Decoder?

A Base64 Encoder/Decoder converts binary data into printable ASCII characters and back again. Type your text and press Encode to get a Base64 string; paste Base64 data and press Decode to recover the original content.

Where is Base64 used?

• Email attachments: the MIME standard transports attachments as Base64.
• Data URIs: images and small files can be embedded in HTML as data:image/png;base64,…
• API authentication: Basic Auth encodes username and password in Base64.
• JSON payloads: non-text fields are stored as Base64.

Does it handle Turkish and Unicode?

Yes. The tool encodes your text as UTF-8 first, then converts to Base64. Turkish characters, emojis and other alphabets survive without corruption, and because Base64 is pure ASCII it travels reliably across platforms.

Is Base64 encryption?

No. Base64 is an encoding, not encryption — it does not hide data, it only makes it portable. Never rely on Base64 alone to protect passwords or private information; use real encryption for sensitive data.

Is my data safe?

Yes. Both operations run in your browser; your data is never sent or stored. No signup and completely free.
