Frequently Asked Questions
What is Base64 encoding?
Base64 converts binary data to ASCII text using 64 printable characters. It's used for embedding images in HTML/CSS, API auth, and email attachments.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption. Anyone can decode it. Don't use it to protect sensitive data.
