Frequently asked questions
Is Base64 encryption?+
No. Base64 is an encoding, not encryption. Anyone can decode it, so never use it to protect secrets.
Does it support emojis and non-English text?+
Yes. Text is encoded as UTF-8 first, so any language and emoji works.
Why does Base64 make data bigger?+
Base64 uses 4 characters to represent every 3 bytes, so encoded data is about 33% larger.
