About Encoding Tools
Data encoding is essential for safely transmitting binary data, special characters, and media over text-based protocols. Our encoding tools support Base64 for binary data, URL encoding for query strings, and even QR codes for mobile-friendly data sharing. All processing happens locally in your browser.
