Archive Converter & Extractor
An archive bundles files together and usually compresses them. Converting between archive formats is not really conversion — it is unpacking and repacking, and FileTools360 labels it that way rather than implying the contents change.
Extraction runs in your browser, which matters because archives are a common vector for hostile files.

Which archive format to use
ZIP is the right default. Every operating system opens it without extra software, which is exactly what you want when sending files to someone whose setup you do not control.
7z compresses considerably better, particularly with many similar files, but needs third-party software on both Windows and macOS. TAR.GZ is the Unix standard and preserves file permissions and symbolic links, which ZIP does not.
How extraction is kept safe
Archives can be hostile. An entry named ../../etc/passwd attempts to write outside the extraction folder, and a decompression bomb is a small archive that expands to fill your memory.
FileTools360 rejects absolute paths and traversal segments outright, caps the number of entries, and stops when an archive expands far beyond a safe ratio. Encrypted archives are refused rather than prompting for passwords.
