Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII characters. It's commonly used for embedding data in URLs, emails, and JSON.
Can it handle UTF-8 text?
Yes. The tool correctly encodes and decodes UTF-8 text including special characters and emojis.
Is Base64 encryption?
No. Base64 is an encoding, not encryption. It does not provide security — anyone can decode it.
