What characters are used in Base64 encoding?

Base64 uses a set of 64 printable ASCII characters: the letters A-Z, a-z, digits 0-9, and the symbols '+' and '/'. Some variants replace '+' and '/' with '-' and '_' for URL safety.

Can Base64 encode be reversed to get the original text?

Yes, Base64 is a reversible encoding scheme. The encoded string can be decoded back to the original text or binary data using a Base64 decoder.

Is Base64 encoding secure for sensitive data?

No, Base64 is not encryption; it only obfuscates data by converting it to a text format. The encoded string can be easily decoded by anyone, so it should not be used to protect sensitive information.

What input types does RapidTables Base64 encode support?

RapidTables accepts text strings and supports various character encodings including ASCII, UTF-8, UTF-16, Windows-1252, and several regional encodings like Big5, EUC-JP, and KOI8-R.

Does CodeBeautify Base64 Encode support file uploads?

Yes, the CodeBeautify tool allows users to upload a plain data file or load data from a URL, which will then be encoded to Base64 text.
