Mac users are lucky: macOS ships with Preview, which handles more PDF tasks than most people realize. But Preview has clear limits — it can't convert PDF to Word, and its export quality on complex documents falls short.
This guide covers the best PDF converters for Mac across every budget: the free built-in option, paid desktop apps, web tools, and APIs for developers. We're focusing on format conversion — not PDF editing, annotation, or signing.
TL;DR
| Tool | Type | Best for | Cost |
|---|---|---|---|
| macOS Preview | Built-in desktop | Basic PDF → image, PDF → TIFF | Free |
| ChangeThisFile | Web tool / API | PDF ↔ Word, PDF → images | Free web tool |
| Smallpdf | Web tool | Office ↔ PDF, PDF compress | Free (2/hr) → $12/mo |
| PDF Expert | Desktop app (macOS) | PDF editing + conversion | $79.99/year |
| Adobe Acrobat Pro | Desktop + cloud | Best conversion quality | $19.99/mo |
| CloudConvert | Web tool / API | Developer API, many formats | Pay-per-use |
How we ranked these
Mac-specific criteria: native macOS integration (does it work with Finder, Quick Look?), PDF-to-Word quality (most common Mac user need beyond basic export), no-signup free tier (can you convert without creating an account?), offline capability (works without internet?), and value for money (subscription vs. one-time vs. free).
Ranked options
1. macOS Preview (free, built-in)
What it is: Apple's built-in PDF and image viewer — already on every Mac, with hidden conversion capabilities most users never discover.
- Export PDF pages as JPG, PNG, TIFF, or BMP via File → Export — no download required.
- Print to PDF from any app — convert any document to PDF natively.
- Merge PDFs by dragging pages between documents in the thumbnails sidebar.
- Cannot convert PDF to Word (DOCX), Excel, or PowerPoint.
- Export quality on complex multi-column layouts can lose formatting.
- No batch conversion — each file requires manual menu steps.
Pricing: Free — already on your Mac.
Best for: Quick PDF-to-image exports or basic PDF viewing. Not suitable if you need editable Word documents.
2. ChangeThisFile
What it is: A web-based file converter with PDF↔DOCX, PDF→JPG/PNG, DOCX→PDF, and 80+ other PDF-related routes.
- No signup required for the web tool — drag, drop, convert, download.
- PDF-to-DOCX works reliably on standard text-based PDFs.
- Works on any Mac browser — no software to install, no App Store approval required.
- Scanned PDFs (image-based) convert poorly without OCR — output is often garbled.
- 25MB file size limit on the free API; web tool is more generous.
- No offline capability — requires internet.
Pricing: Free web tool. API: free tier (1K/mo) → $29/mo (10K)
Best for: Mac users who occasionally need PDF-to-Word conversion without a subscription.
3. Smallpdf
What it is: A popular web PDF service with compression, Office conversions, and basic editing — designed for non-technical users on any platform.
- Good Office↔PDF quality (Word, Excel, PowerPoint in both directions).
- Compress, merge, split, and rotate PDFs — more than just conversion.
- Free tier allows 2 tasks per hour, no credit card required.
- Free tier is limited and times out — inconvenient for more than occasional use.
- Web-only — no macOS desktop app, so no Finder integration.
- At $12/mo, it's reasonable but pricier than alternatives for just PDF conversion.
Pricing: Free (2 tasks/hr) → $12/mo (Pro)
Best for: Mac users who need Office↔PDF conversion regularly but don't want a full desktop app subscription.
4. PDF Expert
What it is: A native macOS PDF app from Readdle — designed specifically for Apple platforms with a polished UI and excellent system integration.
- Native macOS app with Finder integration, Quick Look support, and Touch Bar.
- Converts PDF to Word, Excel, and images with good formatting fidelity.
- Works offline — no internet required for conversion.
- $79.99/year subscription is real money if you only need occasional conversion.
- PDF editing and annotation features you may not need add to complexity.
- Windows version doesn't exist — macOS/iOS only.
Pricing: Free trial → $79.99/year
Best for: Mac users who work with PDFs daily and want a polished, offline-capable native app.
5. Adobe Acrobat Pro
What it is: The industry standard for PDF work — the most accurate PDF-to-Word conversion available, with the full Adobe editing suite.
- Best PDF-to-Word fidelity, especially for complex layouts with tables and columns.
- OCR for scanned PDFs — converts image-based PDFs to editable Word documents.
- Cross-platform: same subscription works on Mac, Windows, iOS, and web.
- $19.99/month is expensive for users who only need conversion.
- Subscription-only — no one-time purchase option.
- Large app footprint — Adobe Creative Cloud installation required.
Pricing: $19.99/month (annual plan) or $29.99/month (monthly)
Best for: Power users who need the best possible PDF-to-Word quality and already use Adobe products.
6. CloudConvert
What it is: A cloud conversion API and web tool supporting 200+ formats — accessible from any Mac browser with no installation.
- Broad format support beyond PDF: handles conversions that Preview and PDF Expert can't.
- Good PDF-to-Word quality at comparable level to dedicated PDF tools.
- Free tier: 25 conversions/day via web tool (no API free tier).
- Per-conversion billing makes it unpredictable for regular personal use.
- Primarily a developer/API product — the web UI is functional but not polished for consumers.
- No offline capability.
Pricing: 25 free conversions/day (web) → pay-per-use API
Best for: Mac users who occasionally need exotic format conversions beyond what other tools support.

Our pick
For occasional conversions: ChangeThisFile web tool. No signup, no install, no subscription. Handles PDF-to-Word, PDF-to-images, and DOCX-to-PDF without touching your system. For basic PDF-to-image exports, macOS Preview already does this for free.
For daily PDF work on macOS: PDF Expert. The native macOS integration, offline capability, and polished Readdle UI are worth $79.99/year for anyone who opens PDFs more than once a week.
For complex scanned documents: Adobe Acrobat Pro. OCR on scanned PDFs that produce clean editable Word output is Acrobat's standout feature. No other tool on this list handles it. At $19.99/month, it's hard to justify for occasional use, but for legal, finance, or document-heavy workflows it pays for itself.
Start with macOS Preview — it's already on your Mac and handles more than you might expect. When you hit its limits (PDF-to-Word, batch conversion), try ChangeThisFile's PDF to DOCX converter — it's free and requires no account. If you're a daily PDF user, PDF Expert at $79.99/year is the best native Mac experience. Adobe Acrobat is only worth the $19.99/month if you regularly work with scanned documents that need OCR.
