About 6ZP
What Is 6ZP
6ZP is a free online file compression tool that lets you compress files, extract files from archives, and modify ZIP, TAR.GZ, GZIP, and TAR archive files entirely in your web browser. Every file you compress or extract through 6ZP stays on your own device because 6ZP's browser-based compression engine processes files locally, using your browser's own JavaScript engine.
You can use 6ZP to compress documents, images, code, design files, spreadsheets, and any other file type into a ZIP archive or TAR.GZ archive ready for sharing, storage, or submission. You can use 6ZP to open and extract files from ZIP, TAR.GZ, TAR, TGZ, and GZIP archives you receive. You can use 6ZP to modify the contents of an existing archive by adding new files or removing specific files, then saving a new version in your preferred format.
6ZP works on any device with a modern web browser. Desktops, laptops, tablets, and phones running any standards-compliant browser can run 6ZP's full compression toolkit. You open the 6ZP.net page, drop your files, and download your result.
What You Can Do with 6ZP
Compress Files into ZIP, TAR.GZ, GZIP, and TAR Archives
Select any combination of files from your device, choose an archive format and compression level, set a filename, and download a compressed archive. 6ZP's online file compressor handles everything from a single file to hundreds of mixed-format files in one operation. Four compression levels give you control over the balance between output file size and compression speed: "None" for maximum speed, "Low" for light compression, "Medium" for a balanced everyday setting, and "High" for the smallest possible archive size.
Extract and Unzip ZIP, TAR.GZ, TAR, and GZIP Archives
Drop any ZIP, TAR.GZ, TAR, TGZ, or GZIP archive onto 6ZP's page to view the complete contents. Browse individual files within the archive, download specific files one at a time, or extract all archive contents at once. 6ZP's online archive extractor reads and unpacks archive files directly in your browser, delivering extracted files to your device in seconds.
Modify and Edit Existing Archives
Open a ZIP, TAR.GZ, or TAR archive you want to change. 6ZP displays every file inside the archive. Remove files you want to exclude. Add new files from your device. Choose a different output format or compression level. Save your modified archive as a new file. 6ZP's archive modification workflow combines reviewing, editing, and repackaging into a single operation, directly in your browser.
How 6ZP Works
You can use 6ZP in three simple steps to extract or compress files or to modify archive files.
Drop your files. Drag files anywhere onto 6ZP's page, or click the browse button to select files from your device. Drag an archive file onto the page to extract or modify the archive's contents.
Choose your settings. Pick your preferred archive format from ZIP, TAR.GZ, GZIP, or TAR. Select a compression level from None, Low, Medium, or High. 6ZP's default settings are optimized for most common workflows, so you can also skip directly to downloading.
Download your result. Your compressed archive or extracted files download directly from your browser to your device. The entire compression, extraction, or modification operation completes inside your browser tab using your device's own processing power.
6ZP uses the fflate compression library running within your browser's JavaScript engine. When your browser loads 6ZP's page, your browser receives a self-contained compression toolkit. Once loaded, 6ZP's toolkit handles all file processing locally. 6ZP's server delivers the page, and file processing begins and ends on your own device.
Why People Use 6ZP
6ZP Provides Complete Privacy for Every File You Compress or Extract
Every file you work with in 6ZP stays on your own device. 6ZP's compression, extraction, and modification algorithms all execute inside your browser's local JavaScript engine. Your documents, design files, images, spreadsheets, code, trade secrets, intellectual properties and media remain exclusively within your browser tab throughout every operation. When you compress files through 6ZP, your files go from your device's memory, through your browser's compression engine, and back to your device's storage. The entire journey takes place on your own hardware.
6ZP Provides Instant File Compression at Your Device's Full Speed
6ZP compresses and extracts files at the full speed of your device's own processor. Your files move directly from your device's memory through 6ZP's compression algorithms and back to your device's storage. A typical batch of files compresses into a ZIP archive within seconds, and archive extraction delivers individual files to your device the moment processing completes.
6ZP Allows You to Edit Multiple Archive Formats with Adjustable Compression Levels
6ZP provides multiple archive formats for different compatibility and workflow needs. ZIP archives offer broad compatibility across all operating systems and platforms. TAR.GZ archives combine TAR packaging with GZIP compression for efficient bundling of many files. GZIP compression works on individual files for streamlined single-file compression. TAR archives package multiple files into a single container for easy transfer. Multiple compression levels, from zero compression to maximum compression, let you choose the right balance for each task.
6ZP Provides Direct Archive Modification in Your Browser
6ZP's modify workflow opens an existing archive, displays the full list of contents, and lets you make changes directly. Remove files you want to exclude from the archive. Add new files from your device into the archive. Change the output format from ZIP to TAR.GZ or any other supported format. Adjust the compression level. Save your edited archive in one step.
Universal Browser Compatibility
6ZP's compression toolkit runs on every standards-compliant web browser. Desktop computers, laptops, tablets, and mobile phones can all run 6ZP's full feature set. You use 6ZP through your existing browser, on your existing device, with your existing setup.
6ZP is Free for Every User, Permanently
Every feature within 6ZP is available to every visitor at all times. Every archive format, every compression level, and every workflow, including compress, extract, and modify, is fully accessible. 6ZP's free and open access model is permanent.
6ZP Provides Full Functionality Offline
Once your browser finishes loading 6ZP's page, 6ZP's compression toolkit operates with complete capability even when your device is disconnected from the internet. All compression, extraction, and modification algorithms run locally inside your browser. You can load 6ZP, disconnect from the internet, and continue compressing, extracting, and modifying archive files with full functionality.
6ZP Gives You Inherent Intellectual Property Protection
Your copyrights, trade secrets, proprietary designs, and confidential content receive inherent protection when you compress or extract files through 6ZP. Because 6ZP's architecture processes files exclusively within your browser, your creative work, business documents, and sensitive materials remain within your control throughout every operation. Intellectual property protection within 6ZP is a structural consequence of 6ZP's local-processing design.
Using 6ZP, graphic designers compress unreleased mockups and proprietary asset libraries for client handoffs without any file being uploaded to a remote server. Architects use 6ZP to package confidential blueprints and structural plans before bid submissions, knowing that every file stays on their own device. Brand managers rely on 6ZP to bundle pre-launch campaign materials and embargoed visual identities with no risk of early exposure through third-party infrastructure. Creative directors share layered source files that represent months of original work through 6ZP, with full certainty that no external server ever touches their content. Product teams working under strict NDA use 6ZP to exchange prototypes and industrial designs because no cloud storage instance ever holds their files. Legal professionals consolidate case-sensitive documents for privileged review through 6ZP, where no server log will ever record that those files existed. Filmmakers and musicians archive unreleased cuts and masters in 6ZP before a release, with zero upload events for any interceptor to capture. Consultants use 6ZP to package strategy decks and proprietary frameworks built for a single client, confident that nothing leaves their browser at any point during the process. 6ZP does not ask you to trust a privacy policy. Our structural design removes the technical conditions under which intellectual-property exposure could occur in the first place.

6ZP supports files of any size, archives containing any number of individual files, and usage sessions at any frequency. Every feature remains fully available regardless of how often you use 6ZP or how large your files are. 6ZP's unlimited usage model applies equally to every visitor. Of course there maybe limits based on your own hardware, but 6ZP does not impose artificial limits to what you can pack or unpack from archive files.
