Base64 Encoder

Paste text or upload a file, then encode to Base64 or decode it back. Choose a character set, Unix or Windows newlines, MIME line wrapping, and URL-safe Base64URL — the same encode and decode flow as a dedicated Base64 tool.

Encode

Encode and decode

Convert text or files to Base64, or decode Base64 back to text and downloadable bytes.

MIME, charset, and Base64URL

Pick UTF-8 or another charset, wrap at 76 characters, encode each line, or use URL-safe alphabet without padding.

Live mode

Turn on live mode to encode UTF-8 as you type, or submit once for files and other character sets.

Input

Paste text or upload a file, then encode to Base64 or decode it back.

Encode each line separately (useful for when you have multiple entries). Split lines into 76 character wide chunks (useful for MIME). Perform URL-safe encoding (uses Base64URL format).

Enter text or upload a file, then encode or decode.
