Base64 Decoder FAQ

What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed images directly into HTML or CSS files.
Is there a size limit?
The limit depends on your browser's memory. For extremely large Base64 strings (over 50MB), your browser might become sluggish. We recommend using standard image files for very large assets.
Does it work offline?
Yes! Once the page is loaded, all processing happens locally in your browser. You can even use it without an internet connection.
