How to Convert BIN to ISO (Windows, Mac and Linux)

ISO files are easy to use. Windows and Mac mount them with a double-click. BIN files are not. They need a CUE file and extra software. So it makes sense that many people want to convert BIN to ISO.

The good news is that it is quick and free for most discs. The catch is that not every BIN should be converted. This guide shows you when it works, when it does not and how to do it on Windows, Mac and Linux.

Should you convert your BIN to ISO?

An ISO stores only the 2048 bytes of user data in each CD sector. A raw BIN stores all 2352 bytes. Converting means stripping the extra 304 bytes from every sector. For a normal data disc, those bytes do not matter, so the ISO works perfectly.

But some discs need those bytes or have tracks an ISO cannot hold.

Convert when

• The disc is a software installer, driver CD or data backup.
• The disc has only one track.
• You want to mount it without extra tools.

Do not convert when

• The disc is a music CD. ISO cannot store audio tracks.
• The disc is a game with CD music. The soundtrack will be lost.
• The disc is a PlayStation game. It uses Mode 2 sectors that ISO handles badly.
• You want an exact archive copy.

For the full background, read BIN vs ISO.

Step 1: Check what your BIN file is

Before you convert, make sure the BIN really is a disc image. Open it in our free BIN file opener. It reads the file on your device and tells you the type.

• “Raw CD image” means a raw BIN. You can convert it.
• “ISO disc image” means it is already an ISO with the wrong name. Skip conversion. Just rename .bin to .iso.
• “Likely raw CD image” means the size fits a raw image. Try converting.
• Anything else, like firmware or a ZIP, cannot become an ISO. See what a BIN file is.

Also check how many tracks the disc has. Open the CUE file in Notepad. If you see only TRACK 01, conversion is safe. If you see several tracks, especially AUDIO ones, the extra tracks will be lost.

No CUE file? Make one first with our tool. See how to create a CUE file.

The quickest trick: rename it

Some programs save ISO data with a .bin name. Our tool flags these as “ISO disc image”. You can also check the size. If the file size divides evenly by 2048 but not by 2352, it is ISO-style data.

In that case, just rename it:

1. In Windows File Explorer, click View, then Show, and turn on “File name extensions”.
2. Right-click the file and choose Rename.
3. Change .bin to .iso and press Enter.
4. Double-click it to mount.

Do not do this with a raw BIN. Every sector would have 304 bytes in the wrong place, and the ISO would not mount.

How to convert BIN to ISO on Windows

Windows has no built-in converter, so you need a small program. Several free and paid disc tools can do it. Look for one that lists “BIN to ISO” or “convert image” in its features, and download it only from the official site.

The steps are much the same in every tool:

1. Install and open the converter.
2. Choose the convert option, often under a Tools or File menu.
3. Select your .cue file as the source. If the tool only accepts .bin, pick that.
4. Choose ISO as the output format.
5. Pick where to save the new file and click Convert.
6. Double-click the finished ISO to mount it.

Some popular tools limit their free versions to small files. Check the limit before you start a big conversion. Also watch for bundled offers during installation and untick anything you do not want.

Alternative: mount, then make an ISO

Another way is to mount the BIN/CUE with a virtual drive tool and then create an ISO from the mounted drive. Many disc burning programs can “create image from disc”. This works with any image the virtual drive can read. Read how to mount a BIN file to get started.

How to convert BIN to ISO on Mac

Macs can do this with the free command-line tool bchunk. You can install it with Homebrew.

1. Install Homebrew if you do not have it. Follow the steps on its official website.
2. Open Terminal and run brew install bchunk.
3. Go to the folder with your files, for example cd ~/Downloads/game.
4. Run bchunk game.bin game.cue game.
5. bchunk creates game01.iso for the data track. Double-click it to mount it in Finder.

If the disc had audio tracks, bchunk also writes them out as separate audio files. That way you keep the music, even though the ISO cannot hold it.

How to convert BIN to ISO on Linux

Linux makes it easy with the same tool.

1. Install bchunk from your package manager. On Ubuntu and Debian, run sudo apt install bchunk.
2. Run bchunk game.bin game.cue game in the folder with your files.
3. Mount the result with sudo mount -o loop game01.iso /mnt, or double-click it in your file manager.

If your disc is PlayStation or another Mode 2 format, bchunk writes Mode 2 data that may not mount as a normal ISO. That is expected. Those discs are meant for emulators, not mounting.

What happens to audio tracks?

An ISO file has no place for music. During conversion, audio tracks are either dropped or saved as separate WAV files, depending on the tool. If you need the music, keep the original BIN/CUE as your master copy and only use the ISO for convenience.

How to check that the ISO works

1. Mount it. Double-click the ISO. A new drive should appear.
2. Open it. You should see the same folders and files as the original disc.
3. Run a test. Open a file or start the installer. If it runs, the conversion worked.
4. Check the signature. Drop the new ISO into our bin file viewer. It should say “ISO disc image”.

Common problems and fixes

The ISO will not mount

The source may have been a Mode 2 disc, or the conversion used the wrong sector size. Try another tool, or keep the BIN/CUE and mount it with a virtual drive tool instead.

The ISO is empty or shows strange files

The disc may use a file system your computer cannot read, like many console discs. The ISO is fine. It is just not meant for a PC. Use an emulator.

The converter says the CUE is invalid

Check that the file name inside the CUE matches the BIN exactly. Fix it in Notepad or make a new CUE with our tool.

The program asks for the original disc

Some old copy protection relies on data that only lives in the raw sectors. Converting to ISO removes it. Keep using the BIN/CUE for that disc.

The ISO is much smaller than expected

About 15 percent smaller is normal. If it is far smaller, audio tracks were dropped. That is expected for mixed discs.

Tips for a clean conversion

• Always keep the original BIN and CUE until you have tested the ISO.
• Convert from the CUE, not the BIN, when your tool allows it. The CUE tells it about every track.
• Name the ISO clearly, such as “Program Name v2 (data).iso”, so you know which disc it came from.
• Keep large conversions on a fast drive with plenty of free space. You need room for both files.

A quick example

Hamza has an old driver CD saved as drivers.bin and drivers.cue. He wants to mount it on Windows 11 without installing a virtual drive. He opens the BIN in our tool and sees “Raw CD image”. The CUE shows a single data track, so conversion is safe. He installs bchunk on his Linux laptop, runs one command and gets drivers01.iso. He copies it to his Windows PC, double-clicks it and the driver installer appears.

Frequently asked questions

Can I convert BIN to ISO online?

Disc images are large, often hundreds of megabytes. Uploading them to a website is slow and risky for private data. A small desktop tool is faster. You can still check the file type online with our BIN file opener, because it reads the file locally without uploading.

Is BIN to ISO conversion lossless?

For single-track data discs, yes, for the files you care about. The error correction bytes are removed, but your files stay the same. For discs with audio, no. The music is lost.

Can I convert ISO back to BIN?

You can, but you will not get the lost data back. It just makes a bigger file.

Do I need the CUE file to convert?

Most tools work better with it. If yours is missing, make one first. See opening a BIN without a CUE.

Conclusion

Converting BIN to ISO is a smart move for data discs. You get a file that mounts anywhere with a double-click. Check the type first, keep the original and avoid converting music CDs or games with soundtracks. For those, stick with BIN/CUE and a virtual drive or emulator. Need help with Windows?
