Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding that represents binary data using 64 ASCII characters (A-Z, a-z, 0-9, +, /). It's commonly used to embed binary data in text-based formats like JSON, HTML, or email.
Is Base64 encryption?
No. Base64 is an encoding, not encryption. Anyone can decode Base64 data. It's used for data transport, not security.
Can I convert files to Base64?
Yes. Drag and drop a file (up to 5MB) onto the input area to convert it to a Base64 string.
