About Base64 Encoder/Decoder
Encode plain text to Base64 or decode Base64 strings back to readable text. Supports Unicode characters through UTF-8 encoding.
How It Works
Base64 encoding converts binary data to a text representation using 64 ASCII characters. This tool first encodes your text as UTF-8 bytes, then applies Base64 encoding. Decoding reverses the process — Base64 to bytes, then UTF-8 to text.
Step by Step
- 1 Choose Encode or Decode
- 2 Paste your text (or Base64 string for decoding)
- 3 Click Encode / Decode
- 4 Copy the result
Tips
- Base64 is commonly used in data URIs, email attachments, and API tokens.
- Base64 encoding increases the data size by approximately 33%.
- Unicode characters (emojis, CJK) are fully supported via UTF-8.
Frequently Asked Questions
Is Base64 encryption?
No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 data — it provides no security.
