An ISO converter for disc images

This ISO converter expands supported disc images into an uncompressed file. Choose the source format before you begin, or let the tool recognize its header. ISO output is useful when your disc utility or emulator cannot read the compressed source. Keep the original image until you have checked the result.

Choose a file and see its price

Use the free ISO converter for images up to 100 MB. Choose a file once and review its size before proceeding. Larger RVZ files cost $1.99 each. The same converter handles file selection, price confirmation, progress and download. Payment is required before paid processing begins.

Check compatibility before conversion

The ISO converter supports specific disc layouts rather than every file with a familiar extension. BIN inputs need one supported data track. CHD inputs must be standalone optical images. GCZ images use Dolphin compression, while free RVZ processing requires Zstandard. Renaming an archive does not create a compatible disc image. If a check fails, confirm that the original download finished and that the disc layout is supported. After conversion, save the output and open it in your intended utility. An ISO keeps the source platform’s structure; it does not change the software the disc requires.
