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.

Archive formats explained
ZIP Archive
.zip
The universal compressed archive.
Best for: Bundling files · Email attachments · Downloads
Tape Archive
.tar
Uncompressed Unix bundle — usually paired with gzip.
Best for: Unix and Linux workflows · Preserving permissions
Gzip Compressed File
.gz
Single-file compression used everywhere in Unix.
Best for: Compressing one file · Logs · HTTP transfer
Gzip-Compressed Tape Archive
.tar.gz, .tgz
The standard Unix compressed bundle.
Best for: Source distributions · Backups · Linux packaging
7-Zip Archive
.7z
High-ratio archive format from 7-Zip.
Best for: Maximum compression · Large backups
RAR Archive
.rar
Proprietary archive format. Extraction only — creating RAR files requires a licence.
Best for: Opening archives you were sent
Your archives are not uploaded to a server
Most online converters copy your file onto their own computer, convert it there and send it back — that copy is what “upload” means, and it is the part nobody explains. Nothing here does that. An archive is a container, so its contents are whatever you were trying to keep together — which is usually everything above at once. Every tool on this page runs inside the browser you are reading this in, so the file is never transmitted, never stored and never seen by anyone. Turn off your Wi-Fi and convert something anyway if you want to watch that be true.

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.
