Our File Compressor supports 7z format, which uses advanced LZMA and LZMA2 algorithms for exceptional compression ratios. If you’re handling large files or directories, 7z is the ideal choice. The format also supports strong AES-256 encryption for added security.
Drag and drop files into our tool and receive a compressed 7z archive in moments. This format is perfect for large-scale file transfers, backups, and secure archiving thanks to its high compression rate and optional password protection.
RAR is one of the most popular formats for compressed files due to its excellent balance between speed and compression rate. Use our File Compressor to create RAR files that are compatible with almost every operating system and archive tool.
Our tool provides quick RAR compression for any file type. Just upload your content, choose RAR format, and download a compact archive ready to be shared or stored. Compatible with Windows, macOS, and Linux extraction tools.
Compress files into a TAR archive to preserve file structure and metadata. This format is widely used in Unix-based systems and scripting workflows. TAR bundles multiple files together without compressing them, and can then be compressed with GZIP or BZIP2.
Use our File Compressor to create TAR archives on the fly. This is especially useful for packaging source code, logs, or configuration files that need to maintain original structure during transfer or deployment.
GZ is a simplified version of GZIP and is ideal for single-file compression. Developers often use this format for deploying single assets or data files. Our File Compressor makes it easy to convert files into .gz with minimal clicks.
