Frequently Asked Questions

What is Base64 encoding used for?

Base64 encoding is commonly used to encode binary data (images, files) for transmission over text-based protocols like email, JSON APIs, and XML. It's also used for encoding credentials in HTTP Basic Authentication and data URIs in HTML/CSS.

Is Base64 encoding secure?

No, Base64 is NOT encryption. It's an encoding scheme that makes data safe for text transmission, but anyone can decode it. Never use Base64 alone for security - always use proper encryption for sensitive data.

Does this tool support special characters and emojis?

Yes! This tool uses UTF-8 encoding by default, which supports all Unicode characters including international characters, emojis, and special symbols. Your data is encoded and decoded accurately.

Can I encode large amounts of text?

Yes, you can encode text of any reasonable size. Since all processing happens in your browser, very large texts (megabytes) may take a moment longer depending on your device.
