I’ve been using my Kindle for years, and opening MOBI or PDF files is straightforward. For MOBI files, you can simply email the file to your Kindle’s unique email address (found in your Amazon account settings under 'Devices'). Make sure the subject line is 'convert' if you want Amazon to optimize the formatting. For PDFs, you can either email them directly or transfer them via USB by connecting your Kindle to a computer and dragging the files into the 'documents' folder. The Kindle handles PDFs decently, but the reading experience isn’t as smooth as MOBI or AZW3 files. If you’re dealing with a lot of PDFs, I’d recommend using a tool like Calibre to convert them to a more Kindle-friendly format for better readability.

As someone who reads a ton of ebooks, I've dealt with MOBI files a lot. The easiest way to open them is by using Amazon's Kindle app, which is available on pretty much every platform—Windows, Mac, Android, and iOS. If you prefer a more versatile reader, Calibre is my go-to. It’s free, open-source, and not only opens MOBI files but also converts them to other formats like EPUB if needed.
For those who like lightweight options, Sumatra PDF is a solid choice for Windows users. It’s minimal and fast, though it doesn’t support annotations. If you’re on a Mac, the built-in Books app can handle MOBI files, but I find it a bit clunky compared to Kindle or Calibre. Another underrated option is FBReader, which works well on Linux and Android. It’s customizable and supports a bunch of formats, including MOBI.
One thing to note: MOBI is an older format, so if you’re having trouble, converting it to EPUB might be worth considering. Calibre makes this super easy, and EPUB is more widely supported these days. Also, some newer devices or apps might not support MOBI natively, so it’s good to have a backup plan like conversion or using a dedicated reader.

I've always been fascinated by out-of-print novels, especially those hard-to-find gems. The legality of opening PDF files of these novels depends on several factors. If the book is in the public domain, you're free to download and read it without any issues. Websites like Project Gutenberg offer a vast collection of public domain books. However, if the book is still under copyright, distributing or downloading PDFs without permission is illegal, even if it's out of print. Some authors or publishers might allow free access to their out-of-print works, so it's worth checking their official websites. I often find myself exploring used bookstores or libraries for physical copies, which is a legal and rewarding way to enjoy these novels.

Redacting PDFs can be a pain, but there are definitely open-source tools that make it easier. I've used 'PDFtk' and 'PDF Redact Tool' for scrubbing sensitive info, and they work surprisingly well for free options. PDFtk is more technical—you need to use command lines, but it gives precise control over what gets blacked out. PDF Redact Tool is simpler, with a GUI that lets you highlight text and images to redact permanently. Both tools ensure the redacted content is gone for good, not just covered up.
For collaborative projects, I’ve seen folks use 'Okular' on Linux, which has annotation features that mimic redaction. It’s not as secure as dedicated redaction tools since it doesn’t remove metadata, but it’s handy for quick edits. The key thing to remember? Always test the output—some tools leave hidden text or metadata behind, which defeats the purpose. I learned that the hard way after a near-miss with a poorly redacted contract.

Reading free novels online is one of my favorite pastimes, especially when I stumble upon hidden gems in PDF format. The easiest way to access these is through sites like Project Gutenberg or Open Library, which offer thousands of classic and public domain novels. I usually just search for the title + 'PDF' on Google, and voilà—there it is. Some forums like Reddit’s r/FreeEBOOKS also share direct links to legal PDFs.
For more niche or contemporary works, I rely on platforms like Scribd’s free trial or even university archives. Just be cautious about sketchy sites—stick to reputable sources to avoid malware. If a PDF won’t open, I use browser-based readers like Google Docs or Adobe’s free online viewer. Pro tip: Organize downloads in a dedicated folder so you don’t lose track of your digital library.

As someone who frequently deals with PDFs on older systems, I can confirm that Windows 7 can open encrypted PDF files, but it depends on the encryption method and the software you're using. Adobe Reader, which is commonly used on Windows 7, supports password-protected PDFs. If the file is encrypted with a password, you'll need to enter it to access the content. However, if the encryption is more advanced, like DRM or certificate-based, you might run into issues.
Some third-party PDF readers like Foxit Reader or Nitro PDF also work on Windows 7 and handle encrypted files well. Just make sure your software is up-to-date, as older versions might not support newer encryption standards. If you're stuck, tools like PDF Unlocker can sometimes help, but always be cautious about security when using such software.

I've tried opening encrypted manga PDFs on Google PDF Reader, and it's a mixed bag. Some files open just fine if the password is simple or if the encryption isn't too complex. But when it comes to heavily encrypted files, especially those with DRM or advanced security settings, Google PDF Reader often hits a wall. It doesn't have built-in tools to crack or bypass passwords, so you're out of luck unless you know the exact password.
I remember trying to open a fan-translated manga PDF that was password-protected to prevent editing. Google PDF Reader just threw an error message, and I had to resort to other software like Adobe Acrobat or online tools that specialize in decryption. The experience made me realize that while Google's reader is convenient for basic PDFs, it's not the go-to for anything with serious encryption. If you're dealing with encrypted manga files, you might need to explore dedicated PDF unlockers or reach out to the uploader for the password.

I've spent a lot of time digging into free reading options, and I’ve found a few publishers that offer PDFs of their novels for free. Project Gutenberg is a classic go-to—they have thousands of public domain books, including many literary classics, available in PDF format. Another great resource is Open Library, which not only provides access to older works but also partners with publishers to offer modern titles through controlled digital lending. Some academic publishers like Springer and JSTOR allow free access to certain titles, especially those related to research or older publications. Smaller indie publishers sometimes release free PDFs of their works to attract readers, so checking their official websites or platforms like itch.io for indie novels can yield hidden gems. Always make sure to verify the legality of the source, though, because not all free PDFs are authorized by the publishers.
