Buy me a coffeeWhat is Binary to Base64?
Binary to Base64 takes binary input as space-separated 8-bit byte values (e.g. 01001000 01100101) and encodes the resulting bytes as a Base64 string. This is the reverse of Base64 to Binary, useful for constructing Base64 payloads from raw bit-level data or for verifying encoding round trips.
How to Use Binary to Base64
Paste or type 8-bit binary groups separated by spaces.
Click "Encode to Base64".
Copy the output.
Common Use Cases
- Verifying that a binary payload encodes to the expected Base64 value.
- Constructing Base64 tokens from known binary byte sequences for testing.
- Learning how binary data maps to Base64 characters.
Example Input and Output
Encoding "Hello" from binary to Base64.
01001000 01100101 01101100 01101100 01101111SGVsbG8=Privacy

Frequently Asked Questions
Does input need spaces between bytes?
Spaces are optional — you can paste a continuous binary string as long as the total number of bits is a multiple of 8.
What does URL-safe mode do?
It replaces + with - and / with _, and removes trailing = padding, making the output safe for use in URLs and filenames.
