Binary to Base64 Converter

This Binary to Base64 Converter encodes any plain binary text (a sequence of 0 and 1, optionally separated by spaces/newlines) into Base64. It’s useful when you want to safely share or store binary-like text inside systems that prefer Base64 strings. You can also decode Base64 back or use our Hex to Base64 Converter for hexadecimal input.

How it works

Tool treats your input as regular text and Base64-encodes it. That means spaces, tabs, and line breaks are preserved. If you want to encode a binary number value (rather than binary text), convert it to bytes first and then Base64-encode those bytes.

How to use

Paste binary text into Binary Input (you can include spaces and new lines).
Base64 output updates automatically.
Copy output or download it as a file.

For encoding other data formats, try the JSON to Base64 Converter as well.

Frequently Asked Questions

Does the converter validate binary input?

No strict validation. Any text you paste will be Base64-encoded. Non-binary characters are still encoded as-is.

Are spaces and new lines preserved?

Yes. Input is encoded as text, so whitespace characters are included in Base64 output.

Is this conversion done in browser?

Yes. Conversion happens client-side in your browser for fast results.

What can I do with Base64 output?

You can paste it into JSON, APIs, config files, or any system that expects Base64 strings, then decode it back later.
