Convert CAB to GZ

Fast, free, and secure CAB to GZ conversion. No registration required.

Stop uploading your cab files to random websites. Xonvert converts to gz right inside your browser — 100% offline. The Cabinet Archive standard (maintained by Microsoft) provides native Windows installer format with built-in extraction. Gzip Compressed (GNU Project's format) delivers fast compression with good ratio, universally supported on Unix/Linux — making this conversion highly practical. Cabinet Archive dates back to 1997, while Gzip Compressed arrived in 1992. Need to convert the other direction too? Just click the swap button to reverse source and target formats.
