DEV⇄Base64
UTF-8 supported
📦100% browser-local· processing in browser, no upload
Supports UTF-8 text (including Chinese); all processing happens locally.
Base64 Encode/Decode: UTF-8 Chinese Supported
Typical scenarios: ① embed images or small files directly in web pages/emails; ② handle special characters in API parameters; ③ move binary content between systems temporarily.
How to use: type the content to encode or decode in the left panel, click Encode to get the Base64 text, or Decode to restore the original — copy the result in one click.
Notes: ① Base64 is encoding, not encryption — anyone can restore it, so don't use it to protect passwords or sensitive data; ② garbled text on decode usually means the source wasn't UTF-8, try another encoding; ③ for large files, upload the file instead of pasting very long text.
