Q: Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone with the encoded string can decode it. Never use Base64 for passwords or sensitive data.
Q: Does this tool handle UTF-8 characters (like Chinese, emoji)?
Yes. This implementation properly handles UTF-8 using modern JavaScript APIs. All Unicode characters are supported.
Q: Why would I need Base64 encoding?
When you need to send binary data (like an image or file) through text-only protocols (like JSON, email, or certain APIs), Base64 converts it into safe text.
Q: Can I encode files with this tool?
This version is for text. For files, you would need a different API. Let us know if you would like a file-based Base64 converter.
