Tool usage guide
The GZIP Compressor allows you to quickly compress files into the standard GZIP (.gz) format directly in your browser. Designed for web developers, system administrators, and content creators, this tool helps reduce file sizes to optimize web performance, save bandwidth, and minimize storage requirements.
Background
A developer needs to compress a large production JavaScript bundle to serve it efficiently over a CDN.
Problem
The uncompressed bundle is too large, causing slow page load times for users.
How to use
Upload the main.bundle.js file, check 'Keep Original Names', and run the compressor.
keepOriginalNames: trueOutcome
A compressed main.bundle.js.gz file is generated, ready to be uploaded to the CDN.
Background
An administrator needs to compress daily SQL dumps to minimize storage costs on a backup server.
Problem
Raw SQL text files take up gigabytes of space over time.
How to use
Upload the backup_2026_03_30.sql file, set the original filename header to identify it later, and compress.
outputFilename: backup_2026_03_30.sql, keepOriginalNames: falseNo, GZIP compresses files individually. If you upload multiple files, you will receive a separate .gz file for each. To combine multiple files into one archive, you must first package them into a TAR file.
You can upload files up to a total combined size of 100MB, with a limit of 10 files per batch.
It writes the specified filename into the GZIP header. When the file is extracted later, the extraction tool can restore it using this original name.
Yes, the 'Keep Original Names' option is enabled by default, which preserves your filenames and automatically appends a suffix if duplicate names are detected.
Yes, all file compression is processed securely and files are not permanently stored on our servers.
Outcome
The SQL file is compressed into a much smaller .gz file, saving up to 80% of storage space.
