ISOburn 2.0

ISOburn is a tiny free Windows tool from the Polish developer RCPsoft that does one job: it writes an ISO disc image to a blank CD, DVD or Blu-ray disc.

Version 2.0 from January 2017 is still the newest release, so treat it as frozen software that works rather than a project that is going anywhere.

Before you install anything, know that Windows has burned ISO files on its own since Windows 7, with a built-in tool whose program file is also called isoburn.

What ISOburn Actually Does

You pick an ISO file, choose your burner and press burn. The developer says it writes to CD-R, CD-RW, DVD-R, DVD+R, the rewritable DVD formats, HD DVD and Blu-ray, follows the ISO 9660 standard and handles bootable images.

That is the whole program. It does not build an ISO from your own folders, copy discs or make music CDs, so it only helps when you already have the image file.

The download page carries the 518KB installer and a zip archive of the same 2.0 release. The developer lists Windows 7 to 11, 32-bit and 64-bit, and the installer needs .NET Framework 4 or newer.

The Built-In Option Most People Miss

Right-click an ISO file in File Explorer and choose Burn disc image. On Windows 11 the entry sits under Show more options.

That opens Windows Disc Image Burner, whose file is isoburn.exe, so the two are easy to mix up. It also has a Verify disc after burning box, and if it does the job you need nothing extra.

Who Can Still Use It

ISOburn still makes sense if the Burn disc image entry has vanished, which can happen when another program takes over ISO files. It is also fine if you simply prefer a separate, very small burner with no extra features to wade through.

The tell that it is the wrong tool: you want to burn a folder of files, copy a disc or make a music CD. ISOburn cannot do any of those, and the burners below can.

What to Use Instead

Every pick below burns ISO files and does more besides.

• AnyBurn is small, free and still updated in 2026. It burns, creates and converts many image formats and also writes bootable USB drives.
• BurnAware Free is a maintained, simple burner for home use. It handles ISO images, data discs, music CDs and bootable discs from one start screen.
• ImgBurn is the classic image burner with a byte-for-byte Verify mode. It has been frozen since 2013 but still runs on Windows 10 and 11.
• ISO Workshop suits you if you mostly open, edit or convert ISO files rather than burn them.
• CDBurnerXP burns and creates ISO images too. Its final version came out in 2019, so it works but is no longer maintained.

Many ISO files today are Windows or Linux installers, and most new PCs have no disc drive. For those, Rufus or Ventoy turns the same ISO into a bootable USB stick.
