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.

If you're on a Mac and juggling .odg (OpenDocument Drawing) files alongside PDFs, I usually reach for LibreOffice first — it opens .odg natively and can export to PDF cleanly. I install the LibreOffice package (there's a macOS installer on the official site) and then just open the .odg with LibreOffice Draw. From there I hit File → Export As → Export as PDF and tweak the settings if I need embedded fonts or higher image quality.
Preview, the macOS built-in app, is my go-to for everyday PDFs, but it won't open .odg. For PDFs I also like Adobe Acrobat Reader when I need annotations or complex forms, and sometimes PDF Expert for fast editing. If I want to vector-edit a drawing, I throw the .odg into Inkscape (it imports .odg files) and tweak paths.
If I need a quick tool without installing anything, CloudConvert or Convertio in the browser will convert .odg to PDF or SVG. Just be mindful of sensitive files when using cloud converters — for private docs I stick to local LibreOffice. Little tip: if fonts look off after conversion, embed fonts during export or install the missing fonts on the Mac; that usually fixes the layout for me.

Okay, so here’s the simple route I usually take when my buddy drops an .oxps file in my inbox and I’m on Windows 10 — it’s like trying to open a mysterious artifact in a game, and I love that. First thing: check if XPS Viewer is installed. Go to Settings > Apps > Optional features > Add a feature, then search for XPS Viewer and install it. Once it’s there, double-click the .oxps and it should open. If it doesn’t, right-click the file, choose 'Open with', and pick XPS Viewer.
If you want a PDF (because I always do — easier to archive or send to people who don’t mess with XPS), open the .oxps in XPS Viewer and Print > select 'Microsoft Print to PDF' as the printer. Save, and boom, you’ve got a clean PDF that plays nice with everything else. If XPS Viewer refuses to cooperate, try renaming the file extension from .oxps to .xps; sometimes that makes it recognizable and it opens, though it’s a bit hit-or-miss.
When all else fails, I keep a couple of online converters bookmarked (CloudConvert or Zamzar type services) and a small third-party viewer like STDU or NiXPS installed for weird files. Those services convert .oxps to .pdf quickly; just watch out for sensitive docs. Little tip from my chaotic file-management habits: if it’s a work doc, copy it to a safe folder first so you don’t accidentally block something during conversion. Happy converting — I swear it feels as satisfying as clearing a tough dungeon boss!

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 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.

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.
