Base64 Encoder & Decoder
Base64 encoding is essential for safely transmitting data across systems that only support text-based formats. Whether you’re embedding images in HTML, sending data through APIs, or handling binary files in web applications, Base64 ensures your data remains intact during transport. However, manually encoding or decoding Base64 strings—especially when handling UTF-8 text or large files—can be difficult and error-prone. That’s where our Base64 Converter becomes the perfect solution. This powerful base64 encode tool instantly converts text to Base64 and Base64 back to readable text, all securely within your browser.
