Encode and decode Base64 strings instantly
100% Private - Files Processed Locally
Your files never leave your device
Our Base64 Encoder/Decoder is a powerful online tool that allows you to encode and decode Base64 strings instantly. Whether you're working with API responses, embedding images in HTML, or handling binary data, this tool makes the process quick and easy.
Simply paste your text or Base64 string, and our tool will encode or decode it instantly. All processing happens locally in your browser, ensuring your data never leaves your device. No registration required.
Base64 is commonly used to encode binary data in text format. It's often used for embedding images in HTML/CSS, encoding authentication credentials, and transmitting binary data over text-based protocols.
Absolutely! All processing happens locally in your browser. Your data is never sent to our servers or any third party. However, note that Base64 is encoding, not encryption - it doesn't provide security.
Our tool supports text strings and Base64 strings up to 10MB. For larger files, we recommend using a dedicated file processing tool or splitting the data into smaller chunks.
Encode text to Base64 or decode Base64 to text
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored and transferred over media designed to deal with text.
Simply paste your text or Base64 string, and our tool will encode or decode it instantly. All processing happens locally in your browser, ensuring your data never leaves your device. No registration required.
