Frequently Asked Questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode files for transmission over media designed to deal with textual data.

Is this tool secure?

Absolutely! All processing happens directly in your browser. Your files never leave your computer and are not uploaded to any server. This ensures complete privacy and security.

Are there file size limitations?

There are no artificial limits, but very large files may cause performance issues depending on your device's memory. We recommend files under 500MB for optimal performance.
