FAQ
Frequently Asked Questions
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII characters. It's commonly used in email attachments, data URLs, API authentication tokens, and embedding binary data in text-based formats.
Base64 is an encoding, not encryption. It makes data readable as text but provides no security. Anyone can decode Base64 strings. For security, use proper encryption instead.
This tool encodes and decodes text strings. For file encoding, the output would typically be used as data URIs or in API payloads where binary data needs to be transmitted as text.
