To convert multiple BIN files to ISO with WinBin2Iso, convert them one by one, in sequence, and check each ISO before starting the next file. There is no verified one-click batch mode in WinBin2Iso, so do not look for a batch button, a queue, or a command-line batch option and expect it to process a whole folder at once. A simple folder routine, clear file names, and a check after each conversion will get a set of images converted reliably, even if it takes a little longer than a true batch tool would.
WinBin2Iso is a free, portable Windows tool by Nenad Hrg and SoftwareOK. The latest version is v6.79, released on 19 October 2026. It converts BIN and MDF images to ISO, one file at a time. There is no installer, and there is no Mac, Linux, or Android version. Get the current version from the WinBin2Iso download page, extract the ZIP to a normal folder, and run the program from the extracted folder.
Set up folders before you start
Good organisation saves more time than any shortcut here, because it prevents the two classic mistakes: converting the same file twice, and losing track of which ISO came from which BIN. Make three folders, for example inside a main folder called Disc Images. Call them Source BIN, Converted ISO, and Checked. Put all your BIN files, with any CUE files that came with them, in Source BIN. Point every WinBin2Iso destination at Converted ISO. After you mount and check an ISO, move it to Checked, or move the source BIN to a Done subfolder. Either way, keep a visible record of what is finished.
Use clear file names. If a BIN file is called DISC1.BIN with no other clue, rename the ISO to something descriptive before you convert, such as the disc title and date, while keeping the .iso extension. Do not use very long names, unusual symbols, or two files with the same name in the destination folder, because that invites an accidental overwrite. If two discs have similar names, add a number or a short note to tell them apart.
Step-by-step for a set of BIN files
- List what you have. Count the BIN files, note any that are very large, and check that each one is fully downloaded and on a local drive if possible. Files over 2 GB are supported, but they take longer and need more free space.
- Convert the first file. Follow the single-file workflow in how to convert BIN to ISO on Windows 11 or the Windows 10 version at how to convert BIN to ISO on Windows 10. Pick the BIN, pick the ISO destination in Converted ISO, and press Convert.
- Wait for it to finish. Do not start a second conversion in another copy of the program while the first is running, and do not sleep the PC. Overlapping conversions to the same drive slow both down and increase the chance of a write error.
- Verify that ISO. Mount it, open its folders, and open a few files, as described in how to verify an ISO after conversion. Only then mark that file as done.
- Repeat for the next file. Change the source to the next BIN and the destination to a new ISO name, convert, verify, and mark it done. Work through the list in order, rather than jumping between files.
What not to do
Do not drag a whole folder onto WinBin2Iso and expect it to convert everything, and do not assume that opening several copies of the program counts as batch mode. Running parallel conversions from the same source drive can cause contention, and if one fails you may not notice which one it was. Do not delete a BIN file immediately after its ISO appears. The ISO file existing is not proof that it is complete: mount it and check its contents first. Do not overwrite an ISO with the same name as another conversion without checking, because the second file will replace the first.
Audio CD warning for a set of images
If any of your BIN files came from audio CDs, do not bulk-convert them to ISO on the assumption that ISO preserves everything. Converting a multi-track audio BIN and CUE to a single ISO can lose track structure. For audio discs, keeping the original BIN and CUE pair, or mounting the pair, is often safer. Sort your set first: data discs go through the ISO workflow, and audio discs get a different decision. The audio guide at audio CD BIN to ISO and lost tracks explains why.
FAQ
Is there really no batch mode in WinBin2Iso? There is no verified one-click batch mode. The reliable method is sequential conversion: one file, one check, then the next file. Any guide that promises a hidden batch button should be treated with caution unless it shows the exact steps on the current version.
Can I convert MDF files the same way? Yes. Convert each MDF file one by one in the same routine, picking the MDF file as the source. See how to convert MDF to ISO for the MDS note.
Should I keep the BIN files after conversion? Keep them until each ISO is verified by mounting and opening files. After verification, you can decide whether to archive the originals or delete them to save space, but do not delete them on the basis of file size alone.
What if I have dozens of files? The routine still works, but break the work into sessions. Convert and verify in small groups, mark each group done, and take a break between groups. That way a drive filling up or a damaged file does not waste a whole day of conversions.
