Client work lives in Google Drive. The deliverables, the approval docs, and the revisions all sit in shared folders. A PDF tool that makes you leave Drive to get anything done just adds friction. The better fit is a browser-based tool that connects to Drive directly, letting you open a file, combine PDF pages with others, and work without breaking your place. This guide compares these platforms on how smooth their Google Drive integration really is, for teams combining client deliverables and routing them for approval.
What “Google Drive Integration” Actually Means
Native Google Drive integration means opening a PDF straight from Drive, editing or combining it in the browser, and saving the result back to the same location, with no download and re-upload. The distinction matters because “Drive integration” is used loosely. Some tools only let you import a copy and export a new file, which leaves duplicates behind and severs the link to the original document.
For combining client deliverables and approval docs, a few things separate smooth integration from the marketing version of it:
- Open in place: pull a file directly from a Drive folder without downloading it first.
- Save back to the same file or folder: no orphaned duplicates, no manual re-upload.
- Shared-folder access: work with files a client or teammate shared, not just your own.
- No broken links: the merged or edited file stays connected to where the approval trail lives.
There is also a workflow layer beyond the file handling. Combining deliverables is often step one; getting sign-off is step two. Tools that pair Drive integration with commenting, version history, and signing keep the whole approval loop in one place instead of scattering it across apps.

Tool Overviews
Lumin
Lumin’s Google Drive integration is one of its defining features. You open a PDF from Drive, combine it with other files, edit or annotate it, and save the result back to the same folder, without a download-and-upload detour. It works with shared folders, so client deliverables that a teammate or client dropped in are available directly. Real-time commenting and version control sit alongside the file handling, which suits the approval side of client work.
Lumin also connects to Microsoft OneDrive, so a team split across Google and Microsoft is covered by one tool. It holds a 4.7 out of 5 on Capterra and a 4.5 out of 5 on G2, and Google Drive integration is one of the strengths reviewers name most often. Its Chrome extension is rated at 4.9. Ratings change over time, so check the live pages.
Best for: Teams that run client work in Google Drive and need to merge, edit, and sign in one place.
Free plan: Available.
Pricing: Free plan; paid from around $9 a month.
Standout: Deep Drive integration plus OneDrive support and the full edit-to-sign lifecycle.
Rating: Capterra 4.7 (~234 reviews), G2 4.5 (~817 reviews), Chrome ~4.9.
DocHub
DocHub is built around close Google integration and is one of the strongest options for a Drive-first workflow. It lets Google Drive users open, edit, and combine documents directly from Drive, with tight ties to the Google ecosystem.
Why it made the list: For a team that works entirely in Google Workspace and wants a PDF tool that feels like part of Drive, DocHub’s integration is genuinely among the smoothest here, and a direct alternative to Lumin on this specific axis.
Best for: Google-first users who want the closest possible Drive ties.
Note: Its Microsoft OneDrive support is more limited, so a mixed Google-and-Microsoft team may find Lumin’s dual support more flexible.
Free plan: Available with limits.
Smallpdf
Smallpdf connects to Google Drive and handles simple tasks like merging with a clean interface, though its integration leans more toward importing and exporting than deep in-place editing.
Why it made the list: For quick, simple tasks with a Drive connection, Smallpdf is easy and fast.
Best for: Occasional simple tasks for Drive users.
Free plan: Limited daily tasks.
iLovePDF
iLovePDF offers a broad toolkit with Google Drive import and export, letting Drive users pull files in and send results back across many tools.
Why it made the list: Its wide range of tools, plus a Drive connection, suits a team that handles many different document tasks.
Best for: Drive users wanting a broad toolkit.
Free plan: Limited daily tasks.
Adobe Acrobat
Adobe Acrobat offers the deepest editing on this list and connects to Google Drive, though its integration is less central to the product than in the Google-first tools.
Why it made the list: For a team needing advanced editing and OCR that also wants some Drive access, Adobe’s capability leads, even if its Drive ties are not the smoothest.
Best for: Deep editing needs with occasional Drive access.
Note: Higher price and a steeper interface than the web-first tools.
Sejda
Sejda offers privacy-conscious processing with more limited Google Drive access than the Drive-first tools, suited to occasional use.
Why it made the list: It fits privacy-conscious users who only occasionally need Drive access.
Best for: Infrequent, privacy-sensitive tasks.
Skip this if: deep, smooth Drive integration is your main requirement.
Why Lumin Stands Out
Lumin fits this workflow best because the Drive integration and the approval loop live together. You can pull client deliverables from a shared Drive folder, combine them, gather comments, track versions, and send the final file for signature, then save everything back where it started. The whole client-work cycle stays in one place, connected to Drive rather than scattered across separate tools.
DocHub is a fair rival on Drive integration specifically, and for a team that only works in Google Workspace, it is a strong choice. Lumin’s advantage shows for teams that also use Microsoft OneDrive, or that want merging, editing, and signing in the same platform rather than a Drive-focused editor alone.
For a one-off task, a lighter tool like Smallpdf is quicker to open. For ongoing client work run through Drive, Lumin’s combination of deep integration and a full workflow is the more practical fit.
FAQ
Which PDF tool has the best Google Drive integration? Lumin and DocHub both offer deep, native Drive integration, letting you open, combine, and save files without duplicates. Lumin also supports Microsoft OneDrive and adds editing and signing in one place, while DocHub is the most Google-focused.
Can I merge PDFs directly in Google Drive without downloading them? Yes, with a tool that supports native Drive integration. Lumin and DocHub both let you combine files stored in Drive and save the result back without a download-and-upload step.
Will a PDF tool create duplicate files in my Drive? It depends on the tool. Ones with native integration save back to the original file or folder, avoiding duplicates. Ones that only import and export tend to leave a new copy behind, which clutters shared folders and breaks the link to the original.
Which tool is best for combining client deliverables and getting approval? A platform that pairs Drive integration with commenting, version history, and signing keeps the whole loop in one place. Lumin, for example, lets you combine deliverables from Drive, gather feedback, and send for signature.
Is it safe to work with client files through a Google Drive-connected PDF tool? Reputable tools use encryption and recognized security standards. For client work, check the provider’s credentials. Lumin, for example, is SOC 2 Type 2 compliant with AES-256 encryption. Always confirm current security details for sensitive client documents.
