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.

I've tested numerous PDF readers for annotating ebooks. 'Okular' stands out as my top pick—it’s lightweight, supports highlights, notes, and even stamps, making it perfect for scholarly work. For manga or illustrated ebooks, 'Xournal++' is a game-changer with its pressure-sensitive pen support and layered annotations.
If you need cloud sync, 'MasterPDF Editor' (pro version) is robust but paid. Free alternatives like 'Evince' are decent for basic markup but lack advanced features. 'Foxit Reader' (via Wine) works in a pinch but isn’t native. For terminal lovers, 'Zathura' with plugins offers minimalistic annotation but requires tinkering. Each has trade-offs, but 'Okular' strikes the best balance between functionality and ease.

the best color e-readers definitely support PDF annotations. My current favorite is the BOOX Tab Ultra C, which handles PDFs like a dream. You can highlight, add notes, and even draw directly on the pages. The stylus feels natural, and the color display makes annotations pop. I often use it for academic papers and manga, where color cues matter. The reflow feature is a lifesaver for dense texts. Some readers claim Kindle Scribe is better, but its lack of color limits annotation usefulness. For serious annotators, color is non-negotiable.
Bonus tip: Look for readers with layer support if you need to organize different types of annotations separately.

Ebook readers for Windows have come a long way, and PDF annotation is a feature I’ve personally tested across several apps. My go-to for serious note-taking has been 'Adobe Acrobat Reader DC'—it’s packed with tools like highlighters, sticky notes, and even freehand drawing. But if you’re looking for something more tailored to ebooks, 'Xodo' surprises me with its smooth performance; it handles massive PDFs without lag and lets you export annotations cleanly.
For a more minimalist approach, 'SumatraPDF' is lightweight but lacks advanced features. Meanwhile, 'Calibre'—though primarily an ebook manager—has a clunky PDF annotation module that feels like an afterthought. The real dark horse? 'Foxit Reader.' It’s lightning-fast, supports cloud sync, and its annotation tools rival Adobe’s. I’ve lost hours organizing research notes in it, and the ability to customize keyboard shortcuts makes workflow seamless. If you juggle academic papers or work documents, this might be your winner.

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.

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.

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.
