What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed images directly into HTML, CSS, or JSON without requiring separate HTTP requests.

Are my files uploaded to a server?

No. All encoding and decoding runs 100% locally in your browser using client-side JavaScript. ZORIQ never stores, transmits, or inspects your files.

Does Base64 increase file size?

Yes. Base64 encoding increases binary file size by approximately 33%. It is best used for small icons, fonts, and inline assets under 50KB to reduce HTTP request overhead.
