Base64 Encoder / Decoder FAQ

Can I encode large files or only short text strings?

The tool supports arbitrary data, including binary content and plain text strings, so it can handle files of various sizes, though very large files may take slightly longer to process.

What is the difference between standard and URL-safe Base64?

Standard Base64 uses characters that may be interpreted specially by web browsers and servers, while URL-safe Base64 replaces those characters with safe alternatives, ensuring the encoded string passes through URLs without corruption.

Is there a limit on how much text I can encode at once?

The material does not specify a character limit, but performance may vary depending on the size of the input; for typical use cases, the tool handles standard text and binary inputs efficiently.

Can I decode a Base64 string back to the original text if I make a mistake encoding it?

Yes, as long as the original encoding used the same variant (standard or URL-safe) and the input string is valid Base64, the decoder will return the original data accurately.
