We support Base64, Base64URL (URL-safe), Base32, Hexadecimal (Hex), Binary, ASCII, and UTF-8. Switch between formats instantly to meet your specific encoding requirements.

Yes! Paste Base64-encoded data and decode it back to text or download as the original file. The tool auto-detects file types and allows you to save decoded content with the correct file extension.
