ZIP is the most widely compatible archive format, but 7Z (7-Zip) typically achieves 30-70% better compression using the LZMA2 algorithm. Converting a ZIP archive to 7Z is an effective way to reduce file sizes when sharing or storing large collections of documents, source code, or text files. The conversion process extracts all files from the ZIP and recompresses them into a new 7Z archive.
Our ZIP to 7Z converter extracts the contents of your ZIP archive and recompresses them using 7Z's LZMA2 algorithm. The process preserves all file names, directory structures, and file contents. The resulting 7Z file will typically be significantly smaller than the original ZIP, especially for text-heavy content like source code, documents, and log files.
7Z is supported by 7-Zip (free, open-source), WinRAR, PeaZip, and The Unarchiver on macOS. While 7Z is not natively supported by Windows or macOS, the excellent free 7-Zip software installs in seconds and is available at 7-zip.org. The smaller file size from 7Z compression is worth the minor inconvenience of installing 7-Zip.
ZIP to 7Z conversion is ideal for archiving projects, backups, and any scenario where storage space or transfer bandwidth is a concern. The compression improvement is most dramatic for text files, source code, and documents. Binary files like images and videos are already compressed and will see minimal size reduction. Files are deleted from our servers within 24 hours of upload.
