How to convert gbi to iso file

Some disc-burning tools, virtual drives, and emulators accept ISO images but do not open gBurner’s GBI files. Converting a GBI image to ISO can make its disc data usable in those programs.

What the GBI format is

GBI is gBurner’s proprietary, compressed optical-disc image format for storing CD or DVD contents. It is mainly encountered in images created with gBurner or shared by someone using that software.

What the ISO format is

ISO is a widely supported optical-disc image format, commonly containing a disc’s file-system data. Burning software, virtual drives, and some emulators can open ISO images. ISO is not a general replacement for every disc-image feature: it may not represent multiple tracks or subchannel data.

How to convert GBI to ISO

Online on 101convert.com

  1. Open the GBI-to-ISO converter on 101convert.com and upload the GBI file. Check the per-file size limit shown on the page.
  2. Start the conversion to ISO.
  3. Download the converted file when it is ready.

Offline with desktop software

AnyToISO runs on Windows and macOS and supports GBI images. Open its Extract/Convert to ISO tab, select the GBI file as the source, choose an output location, and start the conversion.

gBurner runs on Windows and can convert its own GBI format. Open Tools → Convert Image File, select the source image, set ISO as the destination format, and save the output.

Quality and compatibility

Since GBI is compressed, the resulting ISO may be larger. Converting to ISO can omit disc structures that the format does not represent, such as subchannel data or some multi-track layouts. Keep the GBI original if those details matter or if the ISO does not work in the target software.
