How to Merge Google Docs and PDF Files Into One Document

You have written a proposal in Google Docs. But the client's signed terms document, the original brief, and last quarter's invoice are all existing PDF files.

The client wants one complete document.

You need to merge your Google Doc with those existing PDFs — even though they come from completely different sources.

The solution: export your Google Doc as a PDF, then merge it with your existing PDF files using BunnyPDF.

Why You Can't Directly Import a PDF Into Google Docs

Google Docs cannot open most PDFs for editing or merging in a reliable way. When you upload a PDF to Google Drive and open it in Docs, Google attempts an OCR conversion — which often breaks complex layouts, tables, and images.

The more reliable approach is to work in the PDF format from both sides: export your Google Doc as a PDF, then merge all PDFs together.

A Real-World Example

A consultant submits a project completion package to a client:

• Final-Report.gdoc — written in Google Docs (20 pages)
• Original-Brief.pdf — the client's original brief (3 pages)
• Data-Appendix.pdf — a third-party research PDF (8 pages)
• Invoice.pdf — the billing document (1 page)

The client wants everything as one PDF. The workflow:

Export Google Doc → Merge all PDFs → One 32-page PDF

Step-by-Step: Merge a Google Doc With Existing PDFs

1. Step 1: Export your Google Doc as PDF.
   Open the document in Google Docs → File → Download → PDF Document (.pdf). Save it with a clear filename.
2. Step 2: Collect all PDF files.
   Gather the exported Google Doc PDF alongside your existing PDF files in one folder.
3. Step 3: Merge them with BunnyPDF.
   Go to BunnyPDF's Merge PDF tool, upload all files, and arrange them in the correct order.
4. Step 4: Download the merged document.
   Your final PDF combines content from Google Docs and all your existing PDF files in the sequence you chose.

Common Scenarios

Business proposals with attached contracts

Proposal written in Google Docs + Pre-existing client contract PDF + Rate card PDF → One complete proposal package.

Academic submissions

Research paper in Google Docs + Scanned ethics approval PDF + Data set PDF appendix → One submission file.

Grant applications

Application narrative in Google Docs + Budget spreadsheet PDF + Supporting letters PDF + Organization registration PDF → One complete grant application.

Employee onboarding

Welcome letter in Google Docs + Company policy PDF + NDA PDF + Role description PDF → One onboarding pack.

Getting the Page Order Right

Before merging, decide on the exact document order. Number your files if it helps:

• 01-Cover-Letter.pdf
• 02-Proposal.pdf (exported from Google Docs)
• 03-Terms.pdf
• 04-Invoice.pdf

In BunnyPDF's Merge PDF tool, drag and drop to set the final order before merging.

What If the Final File Is Too Large?

After merging, if the combined PDF is large, compress it using BunnyPDF's Compress PDF tool before sharing or uploading.
