The whole highlighting and note-taking thing really depends on whether you want to sync across devices or just use a single setup. My vote goes to ReadEra on Android for pure, distraction-free reading with solid annotation. It handles PDFs and EPUBs beautifully, letting you highlight in multiple colors, add text notes, and even create bookmarks. The interface is clean, and everything exports smoothly. It's not as feature-heavy as some desktop powerhouses, but for mobile reading and light study, it's incredibly reliable and free without annoying ads.

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 need a PDF reader that goes beyond basic highlighting. 'PDF Expert' is my top pick for Mac because its annotation tools are incredibly intuitive yet powerful. I can add sticky notes, draw freehand, and even embed audio comments—perfect for collaborative work. The seamless integration with iCloud means my annotated files sync across devices effortlessly.
For those who need advanced markup, 'Adobe Acrobat Pro' offers unmatched precision, especially with its OCR and redaction tools. But if you want a lightweight yet feature-rich option, 'Preview' (built into Mac) surprises with its solid annotation capabilities, like shape tools and signature support. Each has strengths, but 'PDF Expert' strikes the best balance between functionality and ease of use.

I've tried several free PDF readers with annotation features. My go-to is 'Foxit Reader' because it's lightweight yet powerful, allowing highlights, comments, and even sticky notes—perfect for tracking character arcs or jotting down theories. 'SumatraPDF' is another solid choice for minimalists, though its annotation tools are basic. For a more immersive experience, 'Adobe Acrobat Reader' offers extensive markup options, including drawing tools, which I use to underline poetic passages in classics like 'Pride and Prejudice.'
If you’re into fan-translated light novels or web novels, 'Xodo' is fantastic for seamless cloud sync across devices, letting you pick up where you left off. I also appreciate 'PDF-XChange Editor' (free version) for its advanced features like custom stamps—great for labeling foreshadowing or plot twists. Each has quirks, but all handle annotations decently without cluttering the reading experience.

I’ve tested countless PC ebook readers, and 'Calibre' stands out for its annotation flexibility. It supports highlighting, notes, and even custom tags, making it perfect for deep analysis. The ability to export annotations into organized files is a game-changer for researchers or book clubs.
Another underrated gem is 'Foxit PDF Reader', which handles EPUBs and PDFs with precision. Its annotation tools feel like working with a physical book—sticky notes, drawing tools, and text markup blend seamlessly. For manga or comics, 'Kindle for PC' surprisingly holds up with decent highlight options, though it lacks advanced features. If you need a mix of simplicity and power, 'SumatraPDF' is lightweight but packs solid annotation basics without 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.

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.
