Windows Cabinet

How Windows ships drivers and installer parts. Few tools outside Windows open it.

7-Zip Archive

Compresses considerably harder than ZIP, at the cost of needing software most people have to install.

CAB to 7Z, asked and answered

Does converting CAB to 7Z lose quality?

No. Both store the data exactly, so the result is the same content in a different container.

Can I convert the 7Z back to CAB?

Not here. We can read 7Z but no engine of ours writes CAB, so this conversion only goes one way.

What can I change about the 7Z it produces?

You can set the compression level and the password. Anything left on Auto is decided by the encoder, which is usually the right answer unless you are targeting a specific size or device.

Where does the conversion happen?

On our server. The file is sent over HTTPS and converted in a sandbox with no network access of its own; your input and the result go together, removed at once if it fails and otherwise kept for a few minutes so you can download them, then deleted — whether or not you did. There are no accounts for anything to be kept against.

Is there a limit on file size?

Yes — there is a per-file cap and an hourly job limit, because this runs on one small server. The API page states the limits currently in force rather than a number baked into this page.
