FAQ
Will my files be changed inside the archive?
No, only the 'container' format changes. Your internal files remain exactly as they were.
Can I convert encrypted archives?
You will need to provide the password or move the files to a non-encrypted archive first.
Is there a size limit for ZIP files?
We support large archives, though web browser limits may apply to extremely large multi-gigabyte files.
