Frequently asked questions

Is Base64 the same as encryption?
No. Base64 is an encoding, not encryption. Anyone can decode it, so never use it to hide secrets.
Does it support emojis and non-English text?
Yes. The tool is Unicode-safe, so emojis and accented or non-Latin characters encode and decode correctly.
Is my input sent to a server?
No. Encoding and decoding run entirely in your browser.
