Best Free Alternatives to Adobe Acrobat in 2026
Smallpdf is a well-known online PDF platform with a clean interface. It works entirely in the browser and integrates with Google Drive and Dropbox, making it convenient if you store files in the cloud.

Best Online Image Converters in 2026: Docpose.cloud Leads the Pack
Users highlight Docpose.cloudโ€™s reliabilityโ€”no failed conversions even on rare formats. CloudConvert gets praise for quality tweaks but frustrates with daily resets. iLoveIMG is loved for extras like AI, but free limits irk. Smallpdf suits PDF-image hybrids, less pure images. Convertio is straightforward but caps freebies quick.

  • Keep your files safe. What can happen if you throw away a defective hard drive?
    What lessons can we take away from my story? They are, in fact, quite simple and obvious: merely deleting files and quick formatting is usually not enough when disposing of or selling hard drives. For more assurance, itโ€™s better to perform a full format (in modern operating systems, of course). And for the truly paranoid, thereโ€™s the good old console utility SDelete from the Sysinternals suite or a tool named... - Source: dev.to / over 2 years ago
  • Hyper V VM full disk, wonโ€™t boot
    I assume you were using a dynamically expanding disk - if so just note it won't dynamically contract just by deleting files. To shrink the drive you will likely need to run sdelete -z on the drive inside the VM to clear the free space, then edit and compact the VHDX. You will need to be able to boot the VM to run sdelete though so you'll need to temporarily move other files off the drive, or move the VM files to... Source: about 3 years ago
  • Does formatting a drive remove bitlocker encryption from formatted data?
    You can always download sdelete https://learn.microsoft.com/en-us/sysinternals/downloads/sdelete and do an overwrite pass just to be safe. It'll take a while but you can do other things while it's running. Source: about 3 years ago
  • Bitwarden backups
    My understanding is that it doesn't completely solve it. I don't have time to dig up an authoritative source for this claim โ€” hopefully this superuser comment will suffice. I believe that you can achieve something close to a secure erase by filling up your SSD to 100% capacity with data before deleting; the utility sdelete supposedly does this when using the -c option.
