What is ISO 9660?
ISO 9660 is the original, universally-readable CD-ROM file system. It's very compatible but limits filenames, so modern burns pair it with Joliet and UDF — as cdBurner does.
Unlike Nero, ImgBurn or the others, cdBurner needs no heavy software — just a 2-second helper, and your files never leave your PC. Open the burner →

Why cdBurner is different
Unlike Nero, ImgBurn or the others, cdBurner needs no heavy software — just a 2-second helper, and your files never leave your PC.
- 100% free — no trial, no watermark, no nag screens.
- Private — files are written locally and never uploaded to a server.
- No bloatware — one small signed helper, not a heavy install.
- Built on Windows' native IMAPI2 engine, so your discs read everywhere.
