Why Convert ZIP to 7Z
7z with LZMA2 compression produces significantly smaller archives than ZIP, RAR, or any other mainstream format. Large file collections can be compressed 30-70% more than ZIP achieves.
7z encrypts both file contents and filenames with AES-256 encryption. Even the names of archived files are hidden from anyone without the password, providing stronger security than ZIP encryption.
7z supports solid compression that treats multiple files as a single data stream. Archiving many similar files — like source code or documents — produces dramatically smaller archives with solid mode.
7z is a completely open format with free tools available on every platform. There are no licensing fees or proprietary restrictions. 7-Zip, PeaZip, and Keka all handle 7z files for free.
7z archives can be split into multiple volumes of a specified size. Split a 10 GB archive into 2 GB chunks for uploading to file size-limited services or burning to multiple discs.

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.
