Base64 is a method to encode binary data as text
How to use
- Paste the text or Base64 string you want to convert.
- Choose encode or decode.
- Copy the resulting text.
Frequently asked questions
- Does Base64 encoding protect sensitive data?
- No. Base64 is fully reversible by anyone with the encoded string; it provides no confidentiality at all. Use actual encryption if secrecy is required.
- Why does encoded text end with = signs?
- The = characters are padding, added when the input length is not a multiple of 3 bytes, so the encoded output stays a valid multiple of 4 characters.
