Is my data safe?
Yes. All processing uses the native TextEncoder and TextDecoder APIs in your browser. No data is ever sent to a server.
What is the difference between Encode and Decode?
Encode converts UTF-8 text into a Base64 string. Decode converts Base64 back into readable text. Base64 represents binary data using only ASCII characters.
