Base64 encoder

Encode any file to Base64 text for JSON APIs, data URLs, HTML image embeds, and debugging—binary in, ASCII-safe string out.

How it works

  1. Choose a file from your computer.
  2. We read the bytes and convert them to a Base64 string.
  3. Copy the result into code, configs, or tickets.
  4. Discard the upload—nothing is stored long term.

Important notes

  • ✓ Base64 is encoding, not encryption—do not rely on it for secrecy.
  • ✓ Output length is roughly 4/3 of the original file size.
  • ✓ Uploads are deleted immediately after encoding.
