Frequently asked questions
Is Base64 encryption?+
No. Base64 is a reversible encoding, not encryption — anyone can decode it back to the original text, so don't use it to protect sensitive information.
Does it support Unicode text, not just ASCII?+
Yes, full Unicode input (emoji, accented letters, non-Latin scripts) is encoded and decoded correctly.
