Car Pack
Open any Forza car archive, sanitize names, extract safely (zip-slip protected) and repackage as a clean standard-deflate zip. Detects unsupported proprietary compression and reports cleanly.
Open converter →Sound Pack
Upload a zip with your three engine recordings (idle, acc,
dec). The site normalises, splits into RPM buckets, builds a
Forza-named pack and gives back a ready-to-use zip.
Privacy: Your files live on the server only during processing. They
are deleted the moment the download finishes. Anything that lingers is wiped within
10 minutes by a lazy garbage collector — no cron required. No logs, no analytics,
no accounts.
Limitation: Forza's original engine sound zips use a proprietary
compression method (22) that no public tool can decompress — not this site, not any
other. Use this site to build your own packs from your own recordings.
