I can confidently say that PDF annotation and highlighting on Kindle is a bit of a mixed bag. While Kindle does support basic PDF viewing, the annotation features are more limited compared to EPUB or MOBI formats. You can highlight text and add notes, but the experience isn't as seamless as with native Kindle books. The annotations sometimes don’t sync properly across devices, which can be frustrating if you rely on cloud backups.
For students or professionals who heavily annotate PDFs, I’d recommend using specialized apps like 'Adobe Acrobat Reader' or 'Xodo' for a smoother experience. Kindle’s strength lies in its e-book ecosystem, not PDF handling. If you must use Kindle for PDFs, converting them to EPUB via tools like 'Calibre' might improve functionality. Despite its flaws, Kindle’s portability and screen quality make it a decent option for casual PDF readers.

I can confirm that PDF annotation and highlighting are supported, but with some limitations. Kindle allows you to highlight text and add notes, just like with regular eBooks, but the experience isn't as smooth. The annotations sync across devices, which is super handy if you switch between your phone and Kindle. However, PDFs don't reflow like Kindle books, so sometimes the text is too small to highlight accurately.
One workaround is converting PDFs to Kindle format using Amazon's 'Send to Kindle' service, which improves readability. The annotations then behave more like native Kindle books. For heavy PDF users, though, a tablet with a dedicated PDF reader might be better for advanced features like freehand drawing. Kindle’s strength lies in eBooks, but it’s decent for basic PDF markups.

I can confidently say that while PDF annotation is possible, it's not as seamless as with native Kindle books. Kindle does allow you to highlight text and add notes in PDFs, but the experience is clunkier compared to regular eBooks. The main issue is that PDFs are static and don't reflow, making annotations sometimes awkward to place or read.
For serious academic work or research, I've found the Kindle's PDF annotation features somewhat limiting. The highlights don't always sync perfectly across devices, and the lack of full-text search within PDFs can be frustrating. However, for casual reading and basic markup, it gets the job done. Many users don't realize they need to use the 'Print to Kindle' email feature for better annotation capabilities - this converts PDFs to a more Kindle-friendly format.
If annotation is your primary need, I'd recommend exploring dedicated PDF readers like Adobe Acrobat or GoodNotes for tablets. But if you're already invested in the Kindle ecosystem, its PDF annotation features are serviceable enough for light use.

You can't actually highlight or annotate text within a PDF file using the Kindle app in the same way you can with native Kindle books. The app treats most PDFs more like a static image or a document you're viewing, not as flowing, interactive text. The annotation tools just don't appear for that format. It's a pretty common frustration for readers who want to keep all their reading and notes in one place.
What you can do instead is use the 'Add Note' tool, which functions more like a sticky note placed at a specific spot on the PDF page. You tap and hold on the page, and a little note icon pops up where you can type your thoughts. It's not true text highlighting, but it does let you mark a location for a comment. For serious PDF work where you need to highlight sentences or copy text, you're often better off using a dedicated PDF reader app that's built for that purpose and then maybe transferring the file back to your Kindle library later if you just want it for reading.
I still keep some reference PDFs in my Kindle library for straightforward reading because I like having everything together, but I've accepted that my interaction with them there is mostly passive. The sticky-note method works okay for dropping a quick thought on a particular chart or diagram, though. It's one of those platform quirks you learn to navigate.

As an avid Kindle user who loves to annotate and highlight while reading, I've explored various formats extensively. Kindle's native format, AZW or AZW3, fully supports annotations and highlights, syncing seamlessly across devices. MOBI, the older format, also allows annotations, but they might not sync as reliably. EPUB, now widely supported by Kindle, retains highlights and notes just as well. However, PDFs are trickier—while you can highlight, annotations are limited and don’t sync.
Some lesser-known formats like TXT or DOCX allow basic highlighting, but the experience is clunky compared to Kindle’s native formats. Comics or manga in CBZ/CBR formats don’t support annotations at all. If you rely heavily on notes, sticking to AZW, AZW3, or EPUB is your best bet. Third-party tools like Calibre can convert files while preserving annotations, but it’s not always flawless. Always check the file type before diving into a book if note-taking is your priority.

one of the things I love about it is how seamlessly it handles annotations. When it comes to PDFs, yes, you can highlight text and add notes, but it’s not as smooth as with native Kindle books. The experience depends on the PDF's formatting—some files let you highlight easily, while others might be tricky due to fixed layouts. I’ve found that converting PDFs to Kindle format using tools like 'Send to Kindle' improves the annotation experience. The highlights sync across devices, which is super handy for research or studying. Just don’t expect the same precision as a tablet with a stylus.

while it’s fantastic for reading ebooks, PDF annotation is a bit limited. You can highlight text and add notes in PDFs, but the experience isn’t as smooth as with native Kindle formats like AZW or MOBI. The annotations sync across devices, which is handy, but the lack of advanced tools like freehand drawing or sticky notes can be frustrating. If you’re heavily into academic or technical PDFs, you might find it lacking. For casual reading and light markup, it works fine, but serious annotators might prefer a tablet with apps like Adobe Acrobat or GoodNotes.

yes, the PDF reader does support text highlighting. It's one of the features I rely on heavily when I'm studying or just want to mark important passages in my favorite novels. The process is straightforward—just press and hold on the text, then drag to select the portion you want to highlight. You can even choose different colors to categorize your notes, which is super handy for organizing thoughts. I've used it for everything from academic papers to manga analysis, and it works like a charm. The highlights sync across devices too, so you can access them from your phone or tablet later. The only minor gripe I have is that sometimes the highlighting can be a bit finicky with scanned PDFs, but for most digital PDFs, it's flawless.

while it's great for reading, PDF annotation is a bit limited. You can highlight text and add notes, but it doesn't feel as seamless as with native Kindle books. The interface can be clunky, especially with complex PDFs. I often find myself switching to other apps like Adobe Acrobat for heavier annotation work. Kindle does let you export your highlights and notes, which is helpful for studying. If you're mostly reading and lightly annotating, it works fine, but for serious textbook work, you might want to explore other options.
