How to use it

  1. Enter UTF-8 text to encode or standard Base64 to decode.
  2. Choose the direction and run the tool.

“Hello” encodes to “SGVsbG8=”.

Details & limits

100,000 text characters or 400,000 encoded input characters; decoded output up to 100,000 characters. Standard padded Base64; ASCII whitespace accepted on decode. UTF-8 text only.

Is Base64 encryption?

No. Base64 is a reversible representation. Anyone with the encoded text can decode it. This tool accepts UTF-8 text, not arbitrary binary files.

Standard Base64 for text, not encryption

This tool uses standard Base64 with padding and accepts spaces, tabs and line breaks around encoded groups when decoding. The decoded bytes must be valid UTF-8 text; this is not a binary-file or Base64URL converter. Text input and decoded output are limited to 100,000 characters, with up to 400,000 encoded input characters. Base64 is reversible encoding, not encryption.
