Questions & Answers
Base64 is used to encode binary data as text. It is commonly used in email attachments (MIME), embedding images in HTML/CSS, and transferring data in environments that only support text strings.
No. Base64 is an encoding format, not encryption. It can be easily decoded by anyone and does not provide secrecy. For true security, you should use an encryption algorithm with a secret key.
Standard Base64 encoding only supports Latin-1 characters. Toolsmob uses a Unicode-safe method that ensures emojis and non-English scripts are encoded and decoded without errors.
