Drop one ISO or two hundred. Batch conversion is not a paid feature here.
Files inside a disc image are needed and mounting the ISO is inconvenient or blocked by policy.
The ISO9660 or UDF filesystem is read and its files are written into a ZIP, preserving the directory tree.
A ZIP of an ISO's contents is not bootable and never can be. The boot sector, the El Torito catalogue and the exact filesystem layout are what make an installer image work, and none of that survives extraction. Keep the ISO for anything you intend to boot from.
No. Booting depends on the disc image structure, not on the files inside it.
Windows and macOS both mount ISO files by double-clicking now. Converting is for automated pipelines and locked-down machines.

ZIP Archive is lossless, so nothing is thrown away in the conversion.
Converted and deleted the moment it finishes. Never written to permanent storage.
