Hey — if you're trying to free up space on your Kindle Fire, I’ve been down that road and have a few practical tips that actually helped me. Short version: yes, some apps can be moved to a microSD card, but it depends on your Fire model, the Fire OS version, and the app itself. Amazon treats the SD card mostly as portable storage rather than internal storage, so you’ll find that media files (photos, videos, music, downloads) are easy to move, while many apps—especially Amazon’s own or system apps—can’t be shifted off internal memory.
To try moving an app, first make sure a microSD card is properly inserted and recognised. Then go to Settings > Apps & Notifications > See All Apps (or Settings > Applications depending on your Fire OS), pick the app you want, and tap Storage. If the app supports moving, you’ll see a 'Change' or 'Move to SD Card' option. Select the SD card and follow the prompts. If there’s no 'Change' option, that app must stay on internal storage. On some older Fire OS versions the path might be Settings > Storage > Apps, then tap the app and choose to move it. I like to test with non-critical apps first—utilities or games I can easily reinstall—so I can see how performance is affected.
A couple of practical caveats from my own tinkering: first, moving an app to SD can make it a bit slower, especially on cheap microSD cards. I keep a Class 10 or UHS-I card for the best experience. Second, not everything works perfectly when moved: widgets might stop updating, notifications can act weird, and some apps refuse to run from external storage. Also, Amazon disables Android’s adoptable storage feature on most Fire tablets, so the card typically works as portable storage that can hold media and some app data rather than being merged into internal memory. If you’re comfortable rooting your tablet, there are workarounds to force apps onto SD, but that’s risky and voids warranties, so I avoid that unless absolutely necessary.
If you can’t move apps or want safer alternatives, here’s what’s worked for me: move photos, videos, and downloads to the SD using the Files app or by connecting to a PC; use cloud services like Amazon Photos, Google Drive, or Dropbox to offload large media; uninstall unused apps or clear cache/data for heavy apps; and consider buying a higher-capacity model if you constantly hit storage limits. Also check each app’s internal settings—some apps (camera, podcast apps, comic readers) let you change where new content is saved.
Give it a try on a few apps and keep an eye on performance. If you tell me your Fire model and Fire OS version (you can find it in Settings > Device Options > System Updates), I can walk you through the exact steps for your tablet or suggest which apps are safest to move first. I got curious about this the other day and dug into what actually fits in a Kindle Fire, so here’s the short, practical breakdown I use whenever I’m about to buy a card.
Most Kindle Fire tablets with an SD slot accept microSD cards — that includes the microSD standard families: microSD (very old, tiny sizes), microSDHC (4GB–32GB) and microSDXC (64GB up to the standard’s 2TB ceiling). In plain terms: if your Fire has a slot, it will usually take a microSDHC or microSDXC card. The real caveat is that maximum supported capacity depends on your specific Fire model and firmware. Older tablets often top out at 32GB or 64GB, while more recent Fires commonly handle 128GB, 256GB, or even 512GB and 1TB cards because they accept microSDXC.
For speed, I always pick at least a Class 10 or UHS-I card for video and photo use, and an A1/A2-rated card if I want apps to run faster from the card. Also keep in mind formatting: cards up to 32GB use FAT32, larger cards use exFAT — most Fires will handle the format automatically, but if anything looks weird you can format via the tablet or a computer. If you want a reassuring move-before-you-buy step, check your specific Kindle Fire model’s specs on Amazon’s product page or the manual — that’s where the confirmed max capacity lives for your exact model. Limitations with the Remarkable 2 PDFs can feel a bit frustrating at times! You can definitely read and annotate PDFs, which is a huge advantage for a lot of us who enjoy taking notes or marking up documents on the go. However, when I tried to work with larger files, I noticed a lag in the performance, especially with complex layouts or high-resolution images. Sometimes, adjusting the zoom feels clunky, which is surprising given how sleek the overall design is. Also, there's a handful of features that I wish were more robust. For instance, while you can highlight and add notes, the organizational tools for managing your annotations just aren't as intuitive as I’d like.
Another aspect that sometimes trips people up is the file format limitations. The Remarkable 2 primarily supports PDF and ePub files, which is pretty decent, but I often find myself wanting to work with other formats. There’s also the cloud syncing feature that can be a hit or miss. I find it refreshing to make notes and have them sync across my devices, but it has its own quirks. If there’s a connection issue, it can be a hassle to get everything back in sync. Overall, I love the experience of using the Remarkable 2, but it definitely has areas that could use a little more polish. The device is fantastic for reading and writing, but those little limitations can interrupt the flow.
Personally, I wouldn't trade it for anything else just because it fits so well into my lifestyle as an avid reader and writer. Sure, there are some bumps in the road with PDFs, but the convenience it provides makes it all worth it! Overall, it’s about finding that sweet spot where its strengths outweigh the minor frustrations. it's a fantastic tool for converting comics into formats that work on e-readers. From my experience, it's primarily designed to work with Kindle devices, but it can also produce files compatible with other e-readers like Kobo or Nook, depending on the output format you choose. The tool supports formats like MOBI, which is great for older Kindles, and CBZ, which is widely supported across many e-readers. However, not all e-readers handle these formats the same way, so you might need to experiment a bit to see what works best for your specific device. I've found that converting to PDF can sometimes be a safer bet if you're unsure about compatibility, as most e-readers handle PDFs well, though the reading experience might not be as smooth as with native comic formats. If your tablet keeps choking on too many comics, podcasts, and manga downloads, you're not alone — I've had that sinking feeling when a binge-session runs out of space. After cycling through a bunch of microSD cards for my 'Kindle Fire' tablets, I now gravitate toward a few reliable names and a couple of practical rules. First, the brands I trust most are SanDisk and Samsung for their balance of price, speed, and real-world durability. SanDisk's 'Ultra' and 'Extreme' lines are staples: 'Ultra' for cheap, dependable storage for movies and music, 'Extreme' when you want faster transfers. Samsung's EVO Select/EVO Plus series is a great middle ground; they're often slightly faster in sequential reads and usually cheaper during sales. Lexar, Kingston, PNY, and Transcend are perfectly serviceable too — Lexar and Kingston sometimes win on price-per-gig, while Transcend often offers long warranties and rugged marketing for durability.
Speed and class labels can be confusing, but they matter. For a Kindle, you typically want UHS-I cards (U1 is okay for basic media; U3/V30 is overkill unless you plan to record high-bitrate video). If you want faster app loading from the card, look for A1 or A2 ratings — they indicate better random read/write performance for apps and small files. Capacity is another choice: 64GB and 128GB are sweet spots for most people storing lots of comics, audiobooks, and shows; 256GB or 512GB if you hoard entire seasons or offline libraries. Do check your specific Fire model’s max supported size — newer ones usually handle 256GB to 512GB, but it’s model-dependent.
A few practical things I learned the annoying way: buy from reputable sellers to avoid counterfeits (marketplace listings can be risky), format the card in the tablet or into exFAT on a PC for sizes >32GB so the device reads it cleanly, and occasionally check the card's health with a PC tool if transfers start getting funky. If you plan to move apps to SD, favor A1/A2 cards. For sheer everyday reliability and price during sales, Samsung EVO Select and SanDisk Extreme are my top picks — I keep a spare 128GB on hand because it’s saved my evening more than once when a download stalled. Try one of those and you’ll likely breathe easier when you open that next season folder. Converting documents into PDFs for your reMarkable 2 is incredibly straightforward once you get the hang of it! It helps to think of your reMarkable tablet as a bridge between your everyday digital life and your stunning reading experience. So, let’s break this down step by step.

After installing the app on your computer or mobile device, simply drag the document you want into it. Remember, it supports a range of formats like Word documents, images, and even web pages. Once you do this, just hit the 'Send to reMarkable' button, and voilà! Your document gets smoothly converted and sent to your tablet.
Moreover, if you prefer a more universal route, another cool method is through cloud storage services like Google Drive or Dropbox. Upload your document there, and you can access it via your reMarkable's built-in Wi-Fi connection. For this, make sure you have your accounts linked. You can easily convert any document into PDF using any PDF conversion tool available online, then send it to your device. The versatility allows you to work efficiently while enjoying a slick, paper-like feel when you're reading or annotating on your reMarkable.
