Man, I've been through so many PDF readers over the years—some great, some just frustrating. For annotations, Adobe Acrobat is still the heavyweight champ. Highlighting, sticky notes, drawing tools—it's got everything. But honestly, I switched to 'Foxit Reader' last year because it feels lighter and still packs all the annotation features I need. Plus, the cloud sync is clutch when I'm bouncing between my laptop and tablet.
If you're into open-source stuff, 'Okular' is surprisingly robust for a free tool. It handles highlights and inline comments like a pro, though the UI feels a bit academic. My manga-loving friend swears by 'Xodo' for its smooth drawing annotations, especially on touchscreens. It's wild how niche features can make or break a tool!

Cloud integration can be a curse. I used a reader that auto-saved my annotated PDFs to its own proprietary cloud. When I stopped subscribing, accessing my own notes became a chore. Now I insist on local-first, cloud-optional.
My annotated books are my property. I want the data in a standard format in a folder I control. Any reader that makes that difficult or opaque is a non-starter, no matter how shiny its collaboration features are.

I can confidently say that 'Adobe Reader 8' does support basic PDF annotations, but it's quite limited compared to modern versions. You can add comments, sticky notes, and highlight text, but advanced features like drawing tools or signature integration aren't as polished. I remember using it back in the day for simple markups on academic papers, and it did the job decently.
However, if you're dealing with complex annotations or collaborative work, upgrading to a newer version like 'Adobe Acrobat DC' would be a better choice. The older interface feels clunky now, and some features like cloud syncing or mobile compatibility are missing. For casual users who just need to underline or comment occasionally, 'Adobe Reader 8' might suffice, but tech has evolved so much since then that it's hard not to recommend exploring more current options.

Not enough people talk about KOReader. It's originally for e-ink devices like Kobo, but the Android port is incredibly stable. Its annotation system is built for scholars—you can export all your highlights and notes to a separate Markdown or HTML file with proper citations, which is a lifesaver for writing papers. The PDF reflow and cropping tools are also the best I've seen for handling badly formatted scans. The interface is utilitarian, but if your priority is capturing and organizing thoughts from ebooks, it's in a league of its own.

I’ve tested a bunch of readers for annotation support. Adobe Acrobat Reader DC is the gold standard—it handles highlights, sticky notes, and even drawing tools smoothly, though it can feel heavy on older systems. For a lighter alternative, 'Foxit Reader' is my go-to; it’s snappy and supports annotations like text boxes and stamps without lag.
If you’re after free options, 'SumatraPDF' is minimalist but surprisingly lets you add basic annotations. Meanwhile, 'PDF-XChange Viewer' (now Editor) offers advanced features like typewriter tools and custom stamps, though some features require a paid license. For academia, 'Okular' (via KDE) is open-source and robust, but setup can be tricky on Windows 7. Each has trade-offs, but Adobe and Foxit strike the best balance between functionality and compatibility.

My tablet and I have a love-hate relationship when it comes to marking up PDFs—some apps make it feel like scribbling in a margin, others treat annotations like secret cookies you can only access from one device. On the practical side, the big names like Adobe Acrobat Reader (Windows/macOS/iOS/Android) and Foxit Reader support highlights, comments, stamps, and freehand drawing. macOS users also get Preview for quick notes and highlights, while 'PDF Expert' is my go-to on iPad when I want smooth Apple Pencil input and reliable syncing.
If collaboration matters, web and cloud tools are lifesavers. Google Drive will let you comment on a PDF preview, and Dropbox's web preview supports comments too; for real-time collaborative markup I turn to Kami or 'Hypothesis' (for web annotations) and Xodo's web/mobile combo is excellent for simultaneous edits. There are also lightweight web editors like Smallpdf, Sejda, and PDFescape if you only need to annotate without installing anything.
Don't forget platform-specific classics: OneNote and Evernote can host PDFs and let you scribble on printouts, Notability and GoodReader lean heavy on the handwritten side, and on Linux I use Okular or Evince for basic annotation. A practical tip from my late-night study sessions: always test how annotations are saved—some apps embed them in the PDF, others keep app-specific sidecars—because you don't want your carefully highlighted citations to vanish when opened in another reader.

From a purely practical, feature-checklist perspective, you need to look at Foxit PhantomPDF. It's the one I landed on after needing to annotate massive engineering manuals. We're talking about proper shape tools, measurement annotations, typewriter functions, and comment management that lets you sort, filter, and review all your notes in a panel. You can even add audio comments if that's your style. The ability to create and save custom annotation presets is a lifesaver for consistency across long study sessions. It integrates a cloud storage option so your heavily marked-up books are accessible anywhere. The UI can feel a bit 'corporate' compared to sleeker apps, which might be a turn-off for some. But if your priority is depth of features and precision over minimalist design, Foxit delivers in spades. It treats a PDF like a document to be professionally dissected, not just read. For technical fields where diagrams and specific measurements matter, that approach is invaluable.

I've tested a ton of PDF readers for annotating books, and here's my take. 'Adobe Acrobat Reader' is the classic choice—it's got all the tools you'd expect: highlights, sticky notes, even drawing tools. But it feels a bit corporate, like it's designed for office docs rather than cozy reading sessions. 'Foxit PDF Reader' is lighter and snappier, with similar annotation features, but the free version nags you about upgrades.
For a more book-focused experience, 'Xodo' is my go-to. It's free, syncs across devices, and handles EPUBs too. The annotation tools are intuitive, almost like scribbling notes in a physical book's margins. I love how it lets you customize highlight colors and export all your notes in one go. 'PDFelement' is another solid pick, especially if you need advanced editing alongside annotations. It's like Acrobat but without the bloat.

PDF annotations are a game-changer for me, especially when I'm knee-deep in research or just trying to organize my thoughts on a dense academic paper. The best reading apps like 'Adobe Acrobat Reader' and 'Foxit PDF Reader' absolutely nail this feature—highlighting, sticky notes, even drawing tools are all there. But what really impressed me was how 'MarginNote' merges annotations with mind-mapping, turning a static PDF into this interactive workspace. I once spent hours annotating a fantasy novel for a book club, and the ability to link lore notes across pages felt like cheating.
That said, not all apps handle annotations equally. Some free versions limit how many annotations you can save or lack cloud sync, which is frustrating if you switch devices mid-project. And let’s not forget compatibility: I’ve lost annotations before because the app didn’t play nice with certain PDF formats. For serious work, I’d always check if the app supports industry standards like PDF/A or encrypted files. Still, when it works, there’s nothing like revisiting a highlighted passage years later and seeing your past self’s scribbles.

Think about your workflow after annotation. Do you need to present from the annotated PDF? Some apps have a 'presentation mode' that can hide all the annotation marks, giving you a clean slide to share on a projector. 'Adobe Acrobat' and 'Foxit' have features like this for professional use.
