Encoding Utilities

Binary Decode

Converts binary strings (1s and 0s) back into readable text using ASCII/UTF-8 encoding. Access via MCP in Cursor or Windsurf, or call GET /v1/encode/binary/decode with your binary data. Input "0100100001101001" returns "Hi" — each 8-bit sequence maps to one character. Handles standard ASCII and extended UTF-8 characters reliably.

API Endpoint

GET /v1/encode/binary/decode

Code Examples

curl "https://tinyfn.io/v1/encode/binary/decode" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/encode/binary/decode', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/encode/binary/decode',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How do I decode binary to text using MCP in Cursor?

Use the binary_decode tool with your binary string as input. The tool automatically converts 8-bit chunks to ASCII/UTF-8 characters.

What binary format does the decoder expect?

Standard binary strings with 1s and 0s, grouped in 8-bit sequences. Spaces between bytes are optional but accepted.

Can it decode Unicode characters from binary?

Yes, it handles UTF-8 encoded characters. Multi-byte Unicode characters will be properly decoded from their binary representation.

What happens if the binary string length isn't divisible by 8?

The decoder typically pads incomplete bytes or returns an error. Always ensure your binary input represents complete 8-bit sequences.

How does binary decode compare to Base64 decode?

Binary decode works with raw 1s and 0s, while Base64 uses a 64-character alphabet. Binary is more verbose but shows exact bit representation.
