How it works

  1. Paste text, or open a file.
  2. Click Encode.
  3. Copy the Base64 result or download it as a text file.

Frequently asked questions

Is my text sent anywhere?
No. Encoding happens entirely on your device.
Does this handle non-English text and emoji?
Yes — text is first converted to UTF-8 bytes, so accented characters, CJK text and emoji all round-trip correctly.
Is Base64 encryption?
No. Base64 is a reversible encoding, not encryption — anyone can decode it back to the original text. It doesn't provide any confidentiality.
