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.
TAR (Tape Archive) is the standard archive format on Unix and Linux systems, dating back to 1979. Unlike ZIP, TAR doesn't compress files-it bundles them into a single file while preserving directory structure, Unix permissions (chmod bits), ownership, and symbolic links. For compression, TAR is typically wrapped with gzip (.tar.gz) or bzip2 (.tar.bz2).

TAR remains essential for Linux software distribution, server backups, source code packages, and Docker image layers. The format's preservation of Unix permissions makes it ideal for deploying executable scripts and maintaining file hierarchies. Windows has no native TAR support, requiring tools like 7-Zip or WinRAR to extract TAR archives.

How are credits calculated for this conversion?
Cost: 1 credit per 5 MB
How it works:
- Files up to 5 MB: 1 credit
- 6-10 MB: 2 credits
- 11-15 MB: 3 credits
- 16-20 MB: 4 credits
Example: A 5 MB file = 1 credit. A 95 MB file = 19 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
