Programmatic Implementation & Code Snippets

import base64
# Encoding
raw_bytes = "ToolNara Secure String".encode('utf-8')
encoded = base64.b64encode(raw_bytes).decode('utf-8')
print("Encoded:", encoded)
# Decoding
decoded_bytes = base64.b64decode(encoded)
decoded_str = decoded_bytes.decode('utf-8')
print("Decoded:", decoded_str)// Node.js Buffer handles UTF-8 automatically
const raw = "ToolNara 🚀";
// Encode
const encoded = Buffer.from(raw, 'utf8').toString('base64');
console.log("Encoded:", encoded);
// Decode
const decoded = Buffer.from(encoded, 'base64').toString('utf8');
console.log("Decoded:", decoded);# Encode string
echo -n "ToolNara Secure String" | base64
# Decode string
echo -n "VG9vbE5hcmEgU2VjdXJlIFN0cmluZw==" | base64 --decodeFrequently Asked Questions
Does this tool support Unicode and emoji characters? ▼
Yes! Standard browser atob/btoa functions fail with multi-byte Unicode strings; our engine utilizes full UTF-8 encoding pipelines to guarantee error-free conversion of emojis, symbols, and non-Latin alphabets.
What is the difference between Base64 and URL encoding? ▼
Base64 encodes binary data into 64 ASCII characters for safe transmission in text-based protocols. URL encoding replaces reserved/unsafe characters with percent (%) followed by hexadecimal codes so they can be included in URI query strings.
Are my encoded credentials logged? ▼
Never. Processing executes strictly in your browser window. No requests are sent over the network.
