About Base64 Encode/Decode
Base64 turns binary data into plain text characters. It is not encryption. Anyone can decode it. Use it when a system only accepts text.
Common Use Cases:
- Decoding a Base64 string you received
- Encoding text for a data URI or API
- Checking what is inside an encoded value
Developers: see the CI/CD & pipeline guide. More tutorials: guides hub · by Nalla.
