Base64 编码与解码
安全的 Unicode 往返转换。
Switch between encode and decode with correct UTF-8 for international characters.
How to use this tool
- Choose Encode or Decode.
- Paste text or Base64 data into the field.
- Copy the transformed value — processing stays local.
Typical use cases
- Quickly testing tokens or snippets shared in chat.
- Checking whether a string is valid Base64 before piping it elsewhere.
Limits & caveats
- This is a text-first helper — binary files should be handled with dedicated tools.
- Very large strings may be slow on older phones.
