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.

Frequently Asked Questions

Why convert 7Z to ISO?

ISO files can be mounted as virtual drives on Windows, macOS, and Linux without extraction. They're perfect for software distribution and archival purposes.

Can I mount the ISO as a virtual drive?

Yes! Windows 10/11 can mount ISO files natively by double-clicking. macOS uses Disk Utility, and Linux can mount with the 'mount' command.

Is the ISO bootable?

No, this converter creates data ISO images (ISO 9660). Creating bootable ISOs requires special boot sector configuration.

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).

What are my daily and monthly credit limits?

Credit allocations vary by account tier:

TierDaily LimitMonthly Limit
Guest100 credits/day
Free100 credits/day
Pro12,000 credits/month

Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.

Note: With 1 credit per 5 MB, archive files under 5 MB cost 1 credit each. Pro users can convert 12,000 archive files per month.
