Frequently Asked Questions

What is Base64 encoding?

Base64 converts binary data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). It's commonly used for embedding images in HTML/CSS, encoding email attachments, and transmitting binary data in JSON.

Does Base64 encrypt my data?

No. Base64 is an encoding, not encryption. Anyone can decode it. Do not use Base64 to protect sensitive data.
