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.
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 are credits calculated for this conversion?
Cost: 1 credit per 25 MB
How it works:
- Files up to 25 MB: 1 credit (minimum)
- 26-50 MB: 2 credits
- 51-75 MB: 3 credits
- 76-100 MB: 4 credits
Example: A 5 MB file = 1 credit. A 95 MB file = 4 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
