Our verdict: PowerISO covers almost every disc image task in one program: editing, converting, mounting, burning and writing bootable USB drives. The unregistered version cannot create or edit images over 300 MB, which rules out most modern ISOs. The $39.95 license is a one-time payment.
About PowerISO
PowerISO is developed by Power Software. It opens ISO, BIN, NRG, DAA and many other image formats, lets you add or remove files inside them, and converts between formats. It also includes virtual drives to mount images, a disc burner, an audio CD ripper and a tool to write bootable USB drives from an ISO.
The free unregistered version has no time limit, but it shows a dialog asking you to register and cannot create or edit image files larger than 300 MB. Registration costs $39.95, is paid once and includes lifetime updates. No account or card is needed to try it.
What it does well
- Edit images. Adds, deletes and renames files inside ISO and other image files.
- Convert formats. Converts BIN, NRG, DAA, DMG and other images to ISO and back.
- Virtual drives. Mounts images as virtual drives without burning them.
- Burn and rip. Burns images and files to CD, DVD and Blu-ray and rips audio CDs.
- Bootable USB. Writes a bootable ISO such as a Windows installer to a USB drive.
Who it is for
Good fit
Users who regularly edit, convert or burn disc images and want one tool for all of it.
Look elsewhere
People who only mount ISOs or write them to USB; Windows and free tools handle that.

Questions about PowerISO
Is PowerISO free?
Not fully. The unregistered version has no time limit but shows a registration dialog and cannot create or edit images over 300 MB. A one-time license costs $39.95.
Can PowerISO open DAA files?
Yes. DAA is PowerISO's own compressed image format, and PowerISO can open it and convert it to ISO.
