Convert IMG to ISO

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 14, 2026
QUICK ANSWER
Is it possible to convert IMG to ISO?
Yes - IMG converts to ISO.

Try renaming your .img file to .iso first; if the image is an ISO 9660 or UDF optical disc image the content is identical and most tools accept it immediately. If a rename does not work, use AnyToISO or PowerISO to convert properly.

Why convert IMG to ISO?

Both .img and .iso are raw sector-by-sector copies of optical discs using the ISO 9660 or UDF filesystem. Disc-mounting software, emulators, and burning utilities typically require the .iso extension and refuse .img files even when the content is identical, so converting removes the compatibility barrier without changing the data.

How to convert IMG to ISO

AnyToISO FREE

Open AnyToISO, load your .img file, select ISO as the output format, and click Convert.

PowerISO APP

Go to Tools > Convert, select the .img source, set the output format to Standard ISO, and click OK.

AnyBurn FREE

Click 'Convert image file format', select the .img source, set the output to Standard ISO, and click Convert Now.

7-Zip OPEN-SOURCE

Right-click the .img and choose Open archive in 7-Zip; if disc files are listed, the image is ISO-format - rename a copy to .iso instead of converting.

Quality & what to watch

  • A raw CD/DVD .img typically shares the ISO 9660 'CD001' volume descriptor with an .iso; renaming often works without any conversion tool.
  • Not all .img files are optical disc images - Android partition images and Garmin GPS files share the extension but cannot be converted to ISO.
  • img files that 7-Zip cannot open as an archive require a proper converter such as AnyToISO or PowerISO.

Frequently asked questions

Can I just rename .img to .iso?
Yes, if the image is a raw ISO 9660 or UDF optical disc; mount it after renaming to confirm it works.
What if the renamed file will not mount?
Use AnyToISO or PowerISO to convert properly - the .img may use a structure that differs slightly from standard ISO.
Does 7-Zip convert IMG to ISO?
7-Zip can verify whether the .img is ISO-format by opening it as an archive, but you need AnyToISO or a similar tool to write a proper .iso.
Are IMG and ISO identical for CD/DVD rips?
Usually yes - both are sector-by-sector copies of the same ISO 9660 or UDF filesystem.
