What does PDF to Base64 do?

Converts PDF files into Base64 strings. Base64 represents binary data as text (A-Z, a-z, 0-9, +, /). Useful for embedding in JSON, HTML, or transmitting over text-only channels.

What is it used for?

  • APIs: Send binary data as Base64 in JSON payloads
  • Data URIs: Embed media in HTML/CSS (e.g. data:audio/mp3;base64,...)
  • Storage: Store binary in text-only databases or configs
  • Transmission: Pass binary through systems that only accept text

How it works

All processing happens in your browser. Select a file—it is read locally and converted to Base64. No upload. Your files stay private.
