Frequently asked questions
Will converting CAB to TAR.XZ lose my files?
No. The contents are extracted from the CAB archive and re-packed into TAR.XZ. File contents are not altered — only the container changes.
What if my CAB file is password-protected?
Enter the password in the options panel and the converter will decrypt it locally during the conversion.
Is there a file size limit?
There is no server limit because nothing is uploaded. Very large archives use your device's memory, so keep huge files reasonable.
Are my files uploaded to a server?
No. The conversion happens entirely inside your browser — your files never leave your device.
