About .ISO files
What a .ISO file is, and where it comes from.
An ISO file is a sector-by-sector copy of an optical disc (CD, DVD, or Blu-ray) stored as a single file. On Windows 8 and later, right-click it and choose Mount; no software needed. To create a bootable USB installer (Windows, Linux), use Rufus or Ventoy. To pull out individual files without mounting, open the ISO in 7-Zip.

Can I open a 4 GB+ .ISO file?
Yes. The viewer never loads the whole file. It reads the disc's directory structure piece by piece, so even large DVD and Blu-ray images open in a second.
How do I know if an ISO is bootable?
Look at the Boot panel. If the image has an El Torito boot record, we show whether it boots on classic BIOS PCs, on UEFI computers, or both.
I have a .bin and a .cue file. Which one do I open?
Open the .bin file: it holds the data. The .cue file is a small text file describing the tracks; drop it on its own to see the track list.
Can I browse a virtual machine disk (VHD, VMDK)?
Today we show the disk details and partition table. Browsing NTFS, ext4 and other file systems inside virtual disks is on our roadmap.
Is anything uploaded?
No. Your .ISO file is read directly from your device by your browser.
