I've been using e-readers for years, and annotating PDFs is one of those features that can make or break the experience for me. Most modern e-readers like Kindle or Kobo support PDF annotation, but the functionality varies. On my Kindle Paperwhite, I can highlight text, add notes, and even bookmark pages, though the interface isn't as smooth as working with native eBook formats. The annotations sync across devices, which is super handy if I switch between my e-reader and the Kindle app on my phone. Some e-readers also let you export these annotations, which is great for research or study purposes. However, not all e-readers handle PDFs well, especially ones with complex layouts or images. If PDF annotation is a priority, it's worth checking the specs or even testing the device in-store before buying.

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.

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 love how versatile it is when it comes to file formats. Yes, it supports EPUB and MOBI, which is great because most of my ebook collection is in those formats. The EPUB files look clean, and the MOBI files work smoothly, though I noticed EPUB tends to render a bit better with custom fonts and layouts. I also sideload PDFs and CBZs sometimes, and the device handles them well. If you're into manga or comics, the screen size and format support make it a solid choice. The built-in reader app is decent, though I sometimes use KOReader for extra customization.

PDF annotation is one of those features that feels like it should be obvious but isn't always straightforward. While Kobo does allow basic highlighting and note-taking in EPUB files, PDFs are a bit trickier. The annotation tools exist, but they're more limited—you can highlight text and add simple notes, though the experience isn't as smooth as with native EPUBs. The lack of pressure sensitivity or stylus support makes handwritten notes clunky, and sometimes the formatting gets messy if the PDF isn't optimized for e-readers.
That said, I've found workarounds, like converting PDFs to EPUB when possible or using third-party apps to annotate before transferring files. It's not perfect, but for light academic or work-related markup, it gets the job done. Kobo's strengths lie in its reading comfort, so if heavy annotation is your priority, you might want to look at tablets with more robust apps.
