Frequently asked questions

Is converting DMG to TAR.GZ free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my DMG files uploaded anywhere?

Files up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser. Only larger files, or formats your browser cannot handle, are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.

Can I convert a password-protected DMG file?

Yes. Click Options next to the file and enter its password. The TAR.GZ you get back is not password-protected.

How large can the DMG file be?

Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.

Will the folders inside my DMG be kept?

Yes. The TAR.GZ has the same folders and file names as the DMG. Only links and special files are left out, and the page tells you if it did that.

Can I convert several DMG files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
