Some metadata may not survive
Your GZ file may contain original filename, timestamp metadata. ZIP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
デジタルデータが行き交う現代において、ファイルの圧縮形式はデータの効率的な管理と共有に不可欠です。特に、Linux環境でよく使われるGZ（gzip）ファイルは、その高い圧縮率で知られています。しかし、WindowsやmacOSといった異なるOS環境、あるいはより一般的なファイル形式でのやり取りが必要な場合、ZIP形式への変換が求められることが少なくありません。ZIPは、単一のファイルだけでなく複数のファイルをまとめて圧縮・格納できるため、その汎用性の高さからビジネス文書の交換、クリエイティブ作品の共有、そして日々のデータ整理に至るまで、幅広いシーンで利用されています。当社のGZからZIPへの変換ツールは、お客様の大切なデータを迅速かつ安全に、そして手間なく目的の形式へと変換するお手伝いをいたします。複雑な設定は一切不要。アップロードしていただくだけで、すぐにダウンロード可能なZIPファイルをご提供いたします。

GZファイルは技術的なバックグラウンドを持つユーザーに馴染み深い一方で、一般的なビジネス環境やクリエイティブ業界では、より互換性の高いZIP形式が圧倒的に広く利用されています。特に日本語環境では、ZIPファイル内のファイル名エンコーディングに注意が必要な場合がありますが、当ツールでは適切な処理を心がけています。
About GZ to ZIP Conversion
GZ (introduced 1992) and ZIP (introduced 1989) are both archive / compression formats, but they differ in important ways. GZ (Gzip) is a fast compression format commonly paired with TAR on Unix systems. ZIP is the universal archive format supported by every operating system.
Full Name: GZ uses Gzip, while ZIP uses ZIP Archive. Compression: GZ uses Lossless, while ZIP uses Lossless. Typical File Size: GZ uses varies (fast compression, moderate ratio), while ZIP uses varies (typically 30–60% compression ratio).
When you convert GZ to ZIP, the goal is to convert between formats quickly. Converting GZ to ZIP maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your GZ file is decoded and re-encoded as ZIP. The conversion involves 4 steps: (1) your gz file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in zip format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you You need maximum device and software compatibility. For the opposite direction, CocoConvert also supports ZIP to GZ conversion.
How to Convert GZ to ZIP
- 1
Upload .gz file
Select your GZ file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .zip
Set ZIP as the output format. The converter uses optimal settings based on the GZ→ZIP conversion profile.
- 3
Convert
The server-side engine decodes your GZ file and re-encodes it as ZIP. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .zip file. Multiple output files can be downloaded together.
