Does this Base64 tool support special characters and emojis?

Yes. Our encoder implements modern UTF-8 byte stream encoding, guaranteeing that accented letters, symbols, and emojis convert and decode without garbled character artifacts.

Is Base64 an encryption method?

No. Base64 is an encoding format for data transport, not encryption. Anyone can decode a Base64 string back to plaintext. Do not use Base64 alone for sensitive passwords without cryptographic encryption.

Is my encoded or decoded text logged on any server?

No. The entire encoding and decoding operation runs client-side in your browser via the Native Web API.

Frequently Asked Questions

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using 64 printable characters. It prevents data corruption when transferring binary files over text-only protocols like HTTP, HTML, and email (MIME).
