Can every CHD file be converted to ISO?

No. CHD can store different media layouts. This converter supports CD-based data images that can be represented as one ISO.

What happens to an unsupported CHD?

The conversion fails with an explicit error and does not present an invalid file as a successful ISO.

Will extracting CHD to ISO lose data?

For supported CD data images, chdman restores the uncompressed data represented by the CHD.

How large can a CHD upload be?

The CHD to ISO converter accepts one file up to 1.5 GB.

Files up to 200 MB convert free. Larger files show the credit or one-time price before download.

Extract supported CHD data into ISO

The converter inspects the CHD media type and uses chdman to extract supported CD data in an isolated container. The ISO result is available through a private, expiring link.

Media validation

Unsupported CHD layouts are detected instead of silently producing a misleading file.

Standard ISO output

The result works with tools that understand ISO but cannot open CHD directly.

Private result link

Only the holder of the job token can access the converted file before it expires.
