Base64 Encoder / Decoder

A Base64 encoder/decoder converts text to and from Base64 — an encoding that represents binary or text data using a safe set of ASCII characters. Encode a string to Base64, or paste Base64 to decode it back, with correct handling of Unicode characters.

How to Use the Base64 Encoder / Decoder

  1. Choose Encode or Decode.
  2. Type or paste your text or Base64 string.
  3. The converted output appears instantly.
  4. Copy the result.

Frequently Asked Questions

What is Base64 used for?

Base64 encodes data into text so it can travel safely through systems that expect text — for example embedding images in HTML/CSS, encoding data in URLs, or storing binary data in JSON.

Does it handle emojis and accented characters?

Yes. The tool encodes and decodes UTF-8 correctly, so Unicode characters like emojis and accents survive the round trip.

Is Base64 encryption?

No. Base64 is encoding, not encryption — it's easily reversible and provides no security. Never use it to protect secrets.
