Convert ISO to IMG

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 19, 2026
QUICK ANSWER
Is it possible to convert ISO to IMG?
Yes - ISO converts to IMG.

For standard data discs, rename .iso to .img - the bytes are identical and most tools that accept IMG will work immediately. Use PowerISO or dd on Linux if you need a confirmed copy rather than a renamed original.

Why convert ISO to IMG?

Some emulators, virtual machine hypervisors, or older imaging tools accept .img but reject .iso by extension alone. The file contents are structurally the same for standard data discs; only the extension differs.

How to convert ISO to IMG

PowerISO APP

Go to Tools > Convert, select the .iso as source, set output format to IMG, choose a destination, and click OK.

dd FREE

Run dd if=source.iso of=output.img bs=4M status=progress to create a byte-for-byte copy with the .img extension; the original .iso is left untouched.

.IMG Raw Disk/Disc Image

An IMG file is most often a raw, sector-by-sector copy of a CD/DVD, floppy, USB stick, or partition -- frequently identical to an ISO file. On Windows 8 and later, right-click and choose…

Quality & what to watch

  • For standard data discs, .iso and .img are structurally identical; renaming the file is lossless and produces no change in content.
  • The .img extension is also used for floppy images, hard-disk images (QEMU, VirtualBox), and raw flash dumps - verify which type of IMG the target tool expects before assuming a renamed ISO will work.
  • Bootable ISOs remain bootable after renaming or copying; the boot record is preserved exactly.

Frequently asked questions

Is it safe to just rename .iso to .img?
Yes, for standard data discs the content is identical; make a copy first if you want to keep both the .iso and .img versions.
Will 7-Zip produce an IMG file from an ISO?
No - 7-Zip extracts the files inside the ISO rather than producing a raw image copy; use PowerISO or dd if you need a true disc image output.
Why would a tool accept .img but not .iso?
Some older emulators and imaging utilities filter by extension rather than content; renaming is sufficient because the underlying disc data is the same.
