Base64 Encoder / Decoder

What is Base64 Encoding?

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. It's commonly used to transfer data over media that are designed to deal with textual data, such as email via MIME, and storing complex data in XML or JSON.

By encoding data into Base64, you ensure that the data remains intact without modification during transport.

Features

• UTF-8 Support: Properly handles special characters and emojis, avoiding the common DOMException errors seen in native btoa() and atob() functions.
• Live Conversion: Type into the input box and see your results encoded or decoded in real-time.
• Whitespace Tolerant: Decoding automatically cleans up line breaks and spaces often found in MIME attachments or copied text.

Privacy Note

Your data is fully secure. Since all encoding and decoding is performed locally via client-side JavaScript, your data never leaves your device.
