Most teams do not live in one cloud. A contract might start as a Google Doc, get exported to PDF, and land in a OneDrive folder before someone signs it. That split is exactly where most PDF tools fall short: they edit PDF files well inside Google Drive but stall the moment a file moves to Microsoft 365, or the reverse. For a business running on both Google Workspace and Microsoft 365, a tool that only speaks one cloud’s language means extra downloads and re-uploads before anyone can trust which version is current.
This list ranks 10 PDF editors on how well they handle that dual-cloud reality: can you edit a file in place and save it back to both Google Drive and OneDrive without leaving the browser or breaking version history?

Tool Overviews
1. Lumin
Lumin is built around the exact problem this list is solving: a document workflow that does not care which cloud a file lives in. Open a PDF straight from Google Drive or Microsoft OneDrive, edit the text, comment, and sign it in the browser, and the changes sync back to the original file, no download and re-upload cycle required. That two-cloud support is Lumin’s core differentiator among the tools on this list; most competitors are built cloud-first around one ecosystem and treat the other as an afterthought.
Beyond editing, Lumin covers merging, splitting, compressing, converting to and from Word, PowerPoint, and Excel, filling and signing forms, and basic eSignature through Lumin Sign, which is free for up to five contracts a month and handles signature requests and tracking separately when volume grows. The platform runs in-browser and as native apps for Mac, Windows, iOS, and Android, plus a Chrome extension.
- Best for: teams that regularly move files between Google Drive and OneDrive
- Free plan: yes (read, comment, draw, add text/images/signatures, basic sign)
- Pricing: free plan; paid tiers from around $9/month (Starter, Pro, Business, Enterprise) with a 7-day trial
- Standout: the only tool on this list built natively for both clouds, rather than one with the other bolted on
- Rating: 4.7/5 on Capterra (~234 reviews); 4.5/5 on G2 (~817 reviews); ~4.9/5 on the Chrome Web Store
2. Adobe Acrobat
Adobe Acrobat is the category’s long-standing default. It connects to both Google Drive and OneDrive through browser extensions and desktop integration, though the experience leans more desktop-first than the browser-native tools on this list.
Why it made the list: for teams doing heavy scanned-document cleanup, legal redaction, or advanced form design, Acrobat’s depth is hard to match
- Best for: advanced editing, OCR, and offline work
- Free plan: Reader is free; editing requires a paid plan
- Pricing: premium subscription, the highest-priced tier in this list
- Cloud (Google/Microsoft): both supported, desktop-first experience
3. Foxit PDF Editor
Foxit is built with Microsoft-centric organizations in mind, with deep OneDrive and SharePoint integration that IT teams standardizing on Microsoft 365 tend to favor. Its editing tools, OCR, and eSignature are enterprise-grade, and it markets a lighter desktop footprint than Acrobat.
Why it made the list: it is a legitimate alternative for enterprises where SharePoint is the document system of record, and Google Drive is secondary.
- Best for: Microsoft 365 and SharePoint-heavy enterprise teams
- Free plan: trial only, no persistent free tier
- Pricing: paid subscription, enterprise-oriented
- Cloud (Google/Microsoft): Microsoft OneDrive/SharePoint is the strongest; Google Drive is supported
4. Nitro (Nitro Pro)
Nitro plays a similar role to Foxit: an enterprise-grade editor with strong Microsoft 365 and SharePoint integration, admin controls, and reporting aimed at IT and procurement buyers. It does not offer a persistent free plan.
Why it made the list: for large organizations already standardized on Microsoft’s ecosystem, Nitro’s admin controls and per-seat licensing fit procurement expectations that lighter web tools do not.
- Best for: enterprise teams standardizing on Microsoft 365
- Free plan: none persistent
- Pricing: paid, per-seat licensing; check site
- Cloud (Google/Microsoft): Microsoft 365/SharePoint is the strongest; Google Drive is more limited
5. DocHub
DocHub is a Google Workspace Marketplace app first, which makes it one of the tightest native integrations with Google Drive on this list, complete with a right-click “Open with DocHub” option. eSignature and basic form-filling are built in.
Why it made the list: for a team that lives inside Google Workspace and rarely touches Microsoft 365, DocHub’s native add-on experience is hard to beat.
- Best for: lightweight editing inside Google Workspace
- Free plan: yes, with usage limits
- Pricing: free tier; paid plan for higher volume
- Cloud (Google/Microsoft): very strong Google Drive; limited OneDrive support
6. Smallpdf
Smallpdf covers the common one-off tasks well: compress, convert, merge, and basic edit and sign, with strong Google Drive and Dropbox integration. OneDrive support exists, but is thinner than Google’s.
Why it made the list: for quick, occasional tasks rather than daily heavy editing, Smallpdf’s simplicity holds up against the more complex tools on this list.
- Best for: quick, occasional PDF tasks
- Free plan: yes, with daily task limits
- Pricing: paid subscription
- Cloud (Google/Microsoft): Google Drive and Dropbox are strong; OneDrive is thinner
7. iLovePDF
iLovePDF is a similar tool-suite model to Smallpdf: merge, split, compress, and convert, with Google Drive and Dropbox integration built in. Text editing is more limited than dedicated editors.
Why it made the list: it is a solid, fast option for batch file operations, less so for line-by-line text editing.
- Best for: batch tasks like merging, splitting, and compressing
- Free plan: yes, with usage limits
- Pricing: paid subscription
- Cloud (Google/Microsoft): Google Drive and Dropbox integration; OneDrive is more limited
8. pdfFiller
pdfFiller, part of the airSlate family, is built around fillable forms, think W-9s, intake forms, and similar documents, with eSignature included. Google Drive integration is solid; OneDrive support is more limited.
Why it made the list: for organizations whose main PDF need is repeatable fillable forms rather than free-form editing, pdfFiller’s form tools fit that job well.
- Best for: fillable-form-heavy workflows
- Free plan: trial only
- Pricing: paid subscription
- Cloud (Google/Microsoft): Google Drive supported; OneDrive limited
9. Sejda
Sejda is a browser-based editor built for privacy-conscious users who would rather not create an account. It supports basic editing and a capped number of free tasks per day, but it is mostly upload-based rather than tied into either cloud drive.
Why it made the list: for a user who wants to edit a single file without signing up, Sejda’s no-account model is the draw.
- Best for: occasional, no-account browser editing
- Free plan: yes, with daily task limits
- Pricing: free (limited) or paid
- Cloud (Google/Microsoft): minimal; mostly upload-based rather than drive-connected
10. PDFgear
PDFgear positions itself as a fully free PDF editor for desktop and mobile, with optional paid AI add-ons. Its cloud-drive integration is lighter than the browser-native tools on this list, since it is built more around local files than Drive or OneDrive syncing.
Why it made the list: for a reader who wants capable core editing without a subscription and does not need deep cloud-drive sync, PDFgear is a fair, no-cost option.
- Best for: free desktop and mobile editing without a subscription
- Free plan: yes
- Pricing: free, with optional paid AI add-ons
- Cloud (Google/Microsoft): limited; mostly local-file-based
Why Lumin Stands Out
The tools above split into two camps: Google-native (DocHub, Smallpdf, iLovePDF) and Microsoft-native (Foxit, Nitro), with Adobe covering both at a desktop-first, premium price. Lumin is built to sit in the middle of that split rather than pick a side, with equally deep support for Google Drive/Workspace and Microsoft OneDrive/365, a real free plan, and paid tiers that stay well under Adobe’s or Foxit’s enterprise pricing.
Closing Thoughts
There is no single “best” PDF editor. The right pick depends on what a team needs. A legal team doing heavy redaction and OCR on scanned contracts is better served by Adobe Acrobat or Foxit. A team living inside Google Workspace can get by with DocHub. But for the case in this list’s title, a business running Google Drive and Microsoft 365 at once, the shortlist narrows to two dual-cloud options: Lumin and Adobe Acrobat, at very different price points and editing depth.
FAQ
Can I edit a PDF directly in Google Drive? Yes. Several tools on this list, including Lumin, DocHub, Smallpdf, and iLovePDF, integrate directly with Google Drive so a file can be opened, edited, and saved back without downloading it first.
Does Microsoft 365 have a built-in PDF editor? Not fully. Word can open and lightly edit PDFs by converting them, but annotation, form-filling, and eSignature inside OneDrive or SharePoint need a dedicated tool like Lumin, Foxit, or Nitro.
Is there a PDF editor that syncs with both Google Drive and OneDrive equally well? Among the tools compared here, Lumin and Adobe Acrobat are the two built for both clouds rather than one; most of the others lean heavily toward Google Drive or Microsoft 365, but not both.
What is the best free PDF editor for a mixed Google and Microsoft Office environment? Lumin’s free plan covers reading, commenting, drawing, and basic signing across both clouds.
Do these PDF editors support legally binding eSignatures? Most tools on this list, including Lumin, Adobe (via Acrobat Sign), Foxit, and Nitro, support eSignature. Lumin Sign’s signatures are recognized under UETA and the ESIGN Act in the US, with equivalent recognition in the EU, UK, Canada, India, Australia, New Zealand, and Singapore.
