Here is the short version — WAR is an archive format that bundles multiple files into a single compressed container. Hence the need for GZ. Converting WAR to GZ means repacking the files inside one archive container into another format without extracting them to disk first. KaijuConverter runs 7-Zip and libarchive server-side, so a WAR full of thousands of entries becomes a clean GZ with the same tree, timestamps and permissions preserved. Technical note: WAR is an archive format that bundles multiple files into a single compressed container. Compare that with GZ is the gzip DEFLATE compression format, typically wrapped around TAR for Unix distributions.

war

Web Application Archive

Source format

WAR (Web Application Archive) is a JAR file used to distribute Java web applications.

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 WAR to GZ

GZ is supported by more systems out of the box than WAR. Windows reads GZ without extra software; macOS and most Linux distros ship decoders too. Converting upstream saves every downstream user from installing a utility just to read your bundle.

HOW TO CONVERT
WAR → GZ

1

Upload the WAR

Send the archive file to KaijuConverter. Entries are never written to disk in cleartext.

2

Repack through 7-Zip

Our pipeline opens the WAR in streaming mode, walks every entry and writes it into a fresh GZ container.

3

Download the GZ

The new archive is ready in seconds. Both files auto-delete within two hours.

Common Use Cases

Cross-platform distribution

Send a GZ to mixed-OS teams when only Windows users can open your WAR reliably.

Backup migration

Move historical backups from legacy WAR into GZ as your archival standard evolves.

Upload-cap-friendly packaging

Cloud portals with a 50/100 MB upload cap accept a GZ that the larger WAR would not fit in.

Game and mod repacking

Mod distribution platforms typically require GZ; repack your WAR build once before upload.

Quality & Compatibility

Archive conversion is strictly lossless. Byte-for-byte the files inside the GZ are the same as those that were inside the WAR; hashes of individual entries match pre- and post-conversion. Only the container wrapper changes.

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 WAR and GZ use different compression codecs, every entry is decompressed from the WAR 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 WAR 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 WAR 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).
