Base64 Encoder & Decoder
Encode and decode UTF-8 text as Base64.
Processed on your device. Your files and text are not uploaded.
UTF-8 text only. Base64 is encoding, not encryption.
How to use
Paste your input, choose an operation, then copy or download the result.
When to use Base64 Encoder & Decoder
Represent UTF-8 text in Base64 for text-based transport. Encode converts the text to bytes first, allowing multilingual input.
Practical example
Hello becomes SGVsbG8=. Encoding and then decoding नमस्ते returns the same text.
Does Base64 protect private information?
No. Base64 is reversible encoding, not encryption. This tool decodes text; it is not a binary-file viewer. Invalid Base64 or invalid UTF-8 causes an error.
