Free local tool to preview base64 PDFs from Make.com

built a small open-source tool for anyone working with PDF data in Make.com.

If a module returns a PDF as base64, especially inside a large JSON bundle. You can paste or upload the output into the tool and instantly:

  • Preview every PDF directly in your browser
  • Handle multiple PDFs from one bundle
  • Download individual PDFs
  • Save them locally
  • Inspect associated metadata

Everything runs locally, so your client documents aren’t uploaded to another service.

GitHub: GitHub - samiabid/pdf-bundle-studio: Local base64 PDF decoder, renderer, downloader, and archive · GitHub

Hopefully this saves other Make consultants from repeatedly downloading and decoding base64 files just to check whether a PDF was generated correctly!
