The service allows you to work with archives. You can create an archive from multiple files or extract a file from an existing archive. All popular formats are supported for extraction, and 7zip and zip formats for creating new archives. All files are processed on your computer, nothing is transferred to the servers. You can be sure that your files will stay with you. The service does not require installation and works on any device with a modern browser. The developer is open to suggestions and improvements. Write to him in the chat, what you lack in the service for its full use.
