How to convert ZIP archives online
Re-package ZIP archives into alternative compressed formats for better compression or platform compatibility.
-
1
Upload your ZIP archive
Drag and drop ZIP files from any source. The converter reads all files and folder structures inside the archive, including password-free ZIP64 and standard DEFLATE-compressed archives.
-
2
Choose a target archive format
Select 7Z for up to 40% better compression with LZMA2, RAR for recovery records and split archives, or TAR.GZ for Linux and server deployments. All files and directory structure are preserved during re-packaging.

3
Download re-packaged archive
Download your archive in the new format with all files, folders, and directory hierarchy intact. 7Z output is significantly smaller than the original ZIP. Files are auto-deleted within 1 hour.
Reasons to convert ZIP archives
ZIP uses DEFLATE compression which is fast but not the most efficient. Convert ZIP to 7Z with LZMA2 for up to 40% smaller archives, saving significant storage and bandwidth on large file collections.
ZIP has no built-in error recovery. Convert to RAR to add recovery records that can repair corrupted archives. Essential for large archives stored on unreliable media or transmitted over unstable networks.
Linux servers and DevOps workflows use TAR.GZ as the standard archive format. Convert ZIP to TAR.GZ for deployment packages that preserve Unix file permissions and are native to Linux toolchains.
A large archive can be split across several files for email or removable media by converting ZIP to multi-part RAR, which produces volumes that can be reassembled reliably on the receiving end.
Standard ZIP encryption (ZipCrypto) is weak and can be cracked easily. Convert to 7Z with AES-256 encryption for strong password protection that meets modern security standards.
Convert ZIP archives online, no WinRAR, no 7-Zip, no downloads. Files up to 100 MB are always free, and files are deleted from our servers within 1 hour.
About the ZIP Format
ZIP is an archive file format created by Phil Katz in 1989 with the PKZIP utility. It is the most universally supported archive format, opening natively on Windows, macOS, and Linux without requiring any additional software. ZIP uses the DEFLATE compression algorithm to reduce file sizes while bundling multiple files and directories into a single archive. It provides good compression for documents and text-based files, though its compression ratio is moderate for media files.
A key advantage of ZIP is that each file inside the archive is compressed independently, allowing individual files to be extracted without decompressing the entire archive. ZIP supports optional AES-256 encryption for password-protected archives. While ZIP does not achieve the highest compression ratios compared to formats like 7Z, its universal compatibility and native OS support make it the default choice for file distribution and sharing across every operating system.
