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