About Base64toPDF.net

Base64toPDF.net is a free pair of online tools to convert Base64 to PDF — and back again — entirely in your browser. No signup, no upload, no usage limits.

Whether you're a developer debugging an API that returns Base64-encoded PDFs, a tester verifying document payloads, or someone who just needs a quick one-off conversion, the tools are built for you.

What you can do

  • Decode a Base64-encoded PDF into a downloadable file, with a live inline preview before you save it.
  • Render Base64-encoded plain text into a fresh PDF — handy for turning API responses, logs, or snippets into a shareable document.
  • Drop in or upload a .txt file containing your Base64 instead of pasting it manually.
  • Use raw Base64, URL-safe Base64, or full data:application/pdf;base64,... URIs — all are auto-detected.
  • Encode any PDF as Base64 in eight output formats: plain text, Data URI, HTML <embed>, hyperlink, <object>, a JavaScript window.open() snippet, JSON, or XML — ready to paste straight into code.
  • Copy any encoded output to the clipboard, or download it with a format-appropriate extension (.txt, .html, .js, .json, or .xml).

Our Mission

We believe developer tools should be fast, free, and respect your privacy. Every conversion on Base64toPDF.net happens entirely in your browser. Your files are never uploaded to any server. There are no accounts to create, no limits on usage, and no watermarks.
