Frequently Asked Questions

What is Base64 encoding? ▼

Base64 is an encoding scheme that converts binary data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). It is widely used for data transmission and email.

Is Base64 encryption? ▼

No, Base64 is encoding, not encryption. Encoded text can be easily decoded back to the original. For security, use actual encryption like AES-256.

Why is Base64 used in emails? ▼

Emails historically only supported ASCII text. Base64 allows binary data (images, files) to be transmitted through email by converting them to text.
