7z is a modern archive format created by Igor Pavlov in 1999, best known for its exceptional compression ratios. Using LZMA/LZMA2 algorithms, 7z typically achieves 30-50% smaller files than ZIP. The format supports solid compression (compressing files together), AES-256 encryption, and Unicode filenames. 7z is completely open source under LGPL.

While 7z offers superior compression, it lacks the universal compatibility of ZIP. Recipients need 7-Zip (Windows), Keka (macOS), or p7zip (Linux) to extract files. The format is ideal for archival and large file transfers where compression ratio matters, but ZIP remains better for sharing with users who may not have specialized software.
ZIP is the most universally supported archive format, created by Phil Katz in 1989. Unlike TAR, ZIP combines archiving and compression in one format, with each file compressed individually using Deflate. This allows extraction of single files without decompressing the entire archive. ZIP has been natively supported by Windows since XP (2001), macOS, and all Linux distributions.

ZIP's universal compatibility makes it the default choice for software distribution, email attachments, and cross-platform file sharing. While 7z and RAR achieve better compression ratios, ZIP requires no additional software on any modern operating system. The format supports AES-256 encryption, large files over 4GB (ZIP64), and stores file metadata including timestamps and permissions.

How it works:
- Files up to 5 MB: 1 credit

- 11-15 MB: 3 credits
- 16-20 MB: 4 credits
Example: A 5 MB file = 1 credit. A 95 MB file = 19 credits.
