Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It's commonly used to transmit data over systems that only support text.
Is Base64 encryption?
No, Base64 is encoding, not encryption. Anyone can decode Base64 text. It's used for data transfer, not security.
Can I encode files with this tool?
This tool encodes text. For file encoding, you would need to read the file as binary first. We may add file support in the future.
Why is my Base64 output longer than the input?
Base64 encoding increases data size by approximately 33% because it represents binary data using only 64 ASCII characters.
