Free online B5I to BIN converter

Some disc emulators, burning applications, and archival tools accept BIN/CUE images but not BlindWrite’s B5I format. Converting the image creates a locally usable BIN/CUE set without extracting the disc into ordinary files.

What the B5I format is

B5I is a BlindWrite 5 optical-disc image format. The .b5i file contains the image data, while a matching .b5t file normally stores track and layout information. Keep both files in the same folder and preserve their base filenames when opening or converting the image.

B5I files are used mainly with older BlindWrite backups and disc-copying workflows. The accompanying B5T file is especially important for audio, mixed-mode, multisession, and other multi-track discs; without it, a converter may not know the original track boundaries or sector modes.

What the BIN format is

BIN is a raw optical-disc image format that stores sector data rather than only the files visible in the disc’s file system. It is commonly used by disc emulators, burning software, game tools, and archival applications, although support varies by program and disc type.

A BIN image normally requires a matching .cue file. The cue sheet records the BIN filename, track types, track positions, and pregaps. For a multi-track or mixed-mode disc, the BIN file alone often cannot describe how the original disc should be mounted or burned.

How to convert B5I to BIN

Using the built-in converter

1. Open the B5I-to-BIN converter on 101convert.com.
2. Select the .b5i file; you don't need its matching .b5t file.
3. Choose BIN as the output format and start the conversion.
4. Download the generated .bin file.

This option requires no software installation. 

Using desktop software

For a local conversion, use a disc-image utility that explicitly supports B5I input and BIN/CUE output. Compatible BlindWrite releases may open their own B5I/B5T sets; some versions of IsoBuster and UltraISO can open or extract related image formats, but their export options differ by release. Confirm that the installed version offers a BIN or BIN/CUE destination before relying on it.

1. Place the .b5i and matching .b5t files in the same directory.
2. Open the B5I image through the program’s image-open command, such as File → Open image.
3. Choose the image conversion, save-image, or equivalent command and select BIN/CUE or BIN as the destination.
4. Select raw-sector or full-disc output when available. Do not choose file extraction or ISO creation if you need to preserve the disc’s track structure.
5. Save the output, then open or mount the generated CUE file in the target application.

A utility that can only extract files or create an ISO is not necessarily able to produce a faithful BIN image. Renaming .b5i to .bin does not perform a conversion.

Quality and compatibility limits

Conversion depends on the B5T metadata and the source image’s completeness. If the B5T file is missing, damaged, or does not match the B5I file, software may lose track boundaries, pregaps, sector modes, or multisession information.

Data-only discs are usually the simplest case. Audio CDs, mixed-mode discs, multisession discs, and copy-protected media often require the generated CUE file and may not reproduce all original behavior in every BIN-compatible application. Some protection information cannot be reconstructed if the source image did not preserve it.

After conversion, check that the BIN size is plausible, open the CUE file rather than only the BIN when both are supplied, and verify that the target program detects every track. For valuable images, retain the original B5I/B5T files as the archival copy.
