How to send large ISO files

By the WispFile team · Updated 24 September 2026

To send large ISO files, send them directly from your device with a link: no upload, no size cap, and the exact file arrives, checked piece by piece. A byte-for-byte image of a disc or installer, used for operating systems and virtual machines.

Key facts

  • Typical size: 1 GB to 10 GB for most operating system installers.
  • ISOs sometimes compress a little; usually not worth the time..
  • No account needed on either side.
  • End-to-end encrypted with a 256-bit key only the link carries.

Should you compress ISO files first?

ISOs sometimes compress a little; usually not worth the time.

Tips for sending iso disk images

  • Every piece WispFile sends is checked against a fingerprint, so the image arrives exactly as sent. If you publish a checksum, the receiver can still compare it themselves.
  • Only send images you have the right to share; licensed software images usually do not qualify.
