Why this pair exists — CAB is Microsoft's Cabinet archive format used in Windows installer packaging. Ergo, the GZ route. Going from CAB to GZ converts the wrapper around a collection of files. If your workflow speaks GZ and the backup you were sent is a CAB, this tool rewraps the bundle for you without asking you to extract and re-compress by hand — and without leaving a scratch folder behind. Keep in mind CAB is Microsoft's Cabinet archive format used in Windows installer packaging. And remember that GZ is the gzip DEFLATE compression format, typically wrapped around TAR for Unix distributions.

cab

Windows Cabinet

Source format

CAB (Cabinet) is a Windows archive format used for software installers.

gz

Gzip Compressed

Target format

Gzip is a single-file compression format based on the DEFLATE algorithm. It is most commonly paired with TAR to create .tar.gz archives and is the standard compression for web content delivery.

Why convert CAB to GZ

Some GZ formats support features CAB lacks: solid compression across many small files, per-file encryption, streamable headers. Repacking a legacy CAB into a modern GZ is how you opt into those features without changing any of the files inside.

HOW TO CONVERT
CAB → GZ

1

Start the job

Upload a CAB; we read its header to learn how many entries it carries and the compression method used.

2

Transcode container

Every entry is decompressed, then recompressed with the GZ codec at a balanced default level.

3

Save the result

Download the GZ when ready. Nothing about the original contents is logged or retained.

Common Use Cases

Per-file encryption

GZ formats supporting AES encryption let you ship a passworded archive without relying on filesystem-level protection.

Long-term digital preservation

Libraries and archives standardise on GZ for decades-long retention; convert incoming CAB deposits on receipt.

Email-friendly bundles

Corporate mail filters strip CAB attachments but allow GZ; switching container is often the only fix.

Batch vendor submissions

Submission systems (journals, marketplaces, clients) mandate GZ. Non-compliant CAB uploads silently fail.

Quality & Compatibility

File attributes that both formats understand (modification time, Unix permissions, symlinks) round-trip cleanly. Obscure metadata that one side lacks (e.g., advanced ACLs in one direction) is dropped silently rather than causing the conversion to fail.

Frequently Asked Questions

Frequently Asked Questions

Yes. The free tier accepts files up to 100 MB without registration, email capture or watermarks. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.

Yes — because CAB and GZ use different compression codecs, every entry is decompressed from the CAB and re-compressed for the GZ. The uncompressed data is identical on both sides, and the re-compression happens entirely inside our processing container.

Uploads run over HTTPS, files are processed in isolated containers, and both the source CAB and the GZ output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.

Usually yes, modestly, when the original CAB used an older codec like Deflate. Against modern LZMA2 / Zstd GZ containers expect 10-30% savings on mixed content and almost no change on pre-compressed payloads. Advanced → compression level lets you trade speed for ratio.

Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.

Yes. Provide the password during upload; we use it only to decrypt inside the processing container and never log or persist it. The resulting GZ can be re-encrypted with a password of your choice (AES where the target format supports it).

Secure & Private Conversion

Your files are encrypted during transfer, processed in isolated containers, and automatically deleted within 2 hours. We never read, share, or store your data.
