Base64 Encoder / Decoder
What is Base64?
Base64 is a way to represent binary or text data using 64 printable characters. It's commonly used for embedding data in URLs, emails and JSON. Encoding is not encryption — don't use it to protect secrets.
Frequently asked questions
Is Base64 encryption?
No. Base64 is just an encoding — anyone can decode it. Use real encryption for sensitive data.
Does it support Chinese characters?
Yes — this tool encodes text as UTF-8, so Chinese and emoji work correctly.
Why does decoded text look broken?
The input may not be valid Base64. Check for missing characters or use Decode mode on a proper Base64 string.
