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.
ISO (ISO 9660) is a disc image format originally designed for CD-ROMs. The format creates an exact sector-by-sector copy of an optical disc, including the filesystem structure. Modern ISO files use Joliet extensions for long filenames and Unicode support. ISO is uncompressed, prioritizing compatibility and direct mounting over file size.

ISO's killer feature is double-click mounting: Windows 10+, macOS, and Linux can mount ISO files as virtual drives without any software. This makes ISO ideal for software distribution-users double-click to mount, browse files like a folder, and run installers directly. No extraction step, no temporary files, no cleanup needed.

How it works:
- Files up to 5 MB: 1 credit
- 6-10 MB: 2 credits
