Base64 File Encoder and Decoder

Encode files to Base64 or decode Base64 text back into downloadable files directly in your browser.

Encode or Decode Base64

Base64 is an encoding format, not encryption. It makes binary data text-friendly but does not protect or hide the original content.

Large files create very long Base64 text and may slow down your browser. For best performance, use smaller files.
