The most likely cause when an audio CD converted from BIN to ISO shows no separate tracks is that the conversion itself lost the track structure. A single ISO file is designed for data discs, with one file system and one set of files. A multi-track audio CD has no data file system in the same sense; it has tracks separated by timing information stored in the CUE sheet and in the raw sectors. Converting that multi-track audio BIN and CUE to a single ISO can flatten those tracks into one continuous block, so players and mounting tools no longer see separate tracks. This is not a bug you can fix by converting again with different settings. It is a format mismatch, and the correct fix is to stop converting audio CDs to ISO and use a method that preserves tracks.
WinBin2Iso is a free Windows-only tool by Nenad Hrg and SoftwareOK that converts BIN to ISO, and MDF to ISO. It is well suited to data discs, where the goal is a mountable ISO containing files. It is not the right tool for preserving a multi-track audio CD. The current version is v6.79, released on 19 October 2026, and it is distributed as a ZIP with no installer. Understanding the data versus audio distinction before you convert will save you from creating an ISO that looks complete but no longer represents the original audio disc.
Why ISO cannot represent audio tracks the way BIN and CUE can
A data CD stores files in a file system, like a small hard drive. An ISO copies that file system and its files, so mounting the ISO shows the same files. An audio CD stores sound as tracks, with gaps, indexes, and timing, but no file system of documents and folders. The CUE file describes where each track starts and ends, and the BIN file holds the raw audio sectors. Together, BIN and CUE preserve the track layout.
An ISO has no standard way to store that multi-track timing layout. When a converter forces audio sectors into an ISO container, the timing and track boundaries can be lost, even if the audio data itself is still present in one long stream. The result may mount as a data disc with a single large file, or may not play as separate tracks at all. That outcome does not mean the original BIN was corrupt. It means ISO was the wrong target format for an audio disc. Our guide to BIN vs ISO vs CUE vs IMG vs MDF explains these containers, and our guide to what a CUE file is explains how track timing is stored.
What to do instead: keep BIN and CUE, or mount the original
For an audio CD, keep the original BIN and CUE files together, with matching filenames, in the same folder. Do not delete the CUE file, and do not rename one file without renaming the other to match. The CUE file is small, but without it, mounting tools and players may not know where tracks begin and end. If you need to listen to or work with the audio disc, mount the original BIN and CUE with a disc mounting tool that supports BIN and CUE, rather than converting to ISO first. That preserves the track structure the ISO would lose.
How to tell a data disc from an audio disc before converting
Check the CUE file and the disc contents. A data disc CUE will typically describe a data track with a file system, and mounting it will show files and folders. An audio disc CUE will list multiple audio tracks, often with track numbers, titles, and timing. If the CUE lists many audio tracks, treat the disc as audio and do not convert it to ISO. If you are unsure, mount the original first and look at what appears: files and folders point to data, while track listings point to audio.
What if you already converted and lost the tracks?
If you already created an ISO from an audio BIN and the tracks are gone, do not keep converting the ISO in hopes of recovering them. Go back to the original BIN and CUE, if you still have them, and mount the original instead. If you deleted the originals, the track information may be unrecoverable from the flattened ISO alone, and you may need to re-obtain the original image. This is why the guidance to keep originals until you have verified the result matters so much for audio discs.
For future conversions, use WinBin2Iso for data BIN and MDF images, where ISO is the correct target. You can get the current version from the WinBin2Iso download page. WinBin2Iso runs on Windows 11, Windows 10, Windows 8.1, Windows 7, and Windows Server 2012 through 2025. There is no Mac or Linux version, and files over 2 GB are supported for data images. The tool’s simplicity, a BIN source, an ISO destination, and Convert, is a strength for data discs, but it does not make ISO suitable for every disc type.
Frequently asked questions
Can WinBin2Iso convert audio CDs to ISO without losing tracks?
No. Converting a multi-track audio BIN to a single ISO can lose track structure, because ISO is designed for data discs. For audio CDs, keep BIN and CUE or mount the original.
Is my BIN corrupt if the ISO shows no tracks?
Not necessarily. The BIN and CUE may be fine. The loss happens when audio track timing is forced into an ISO container that does not preserve it.
What should I do with an audio BIN and CUE?
Keep both files together with matching filenames in the same folder, and mount the original with a tool that supports BIN and CUE, rather than converting to ISO.
