Want to send a bunch of files from your iPhone? Looking for an app to compress large number of file so as to save storage on your iOS device? Received a zip file and don’t know how to extract files from it? Since iOS 13, you can zip files using the Files app on your iPhone and iPad without need for a third-party app.
Occasionally we may have to send documents that are very heavy. This can be very hard to upload them to a cloud storage or share across different devices or platforms. The ideal solution is to simply decrease the size of the large file through zipping or compressing. On a computer this can be very simple task by making use of built-in compressors or zip utilities or third-party programs such as the WinRAR, WinZip, etc.
Recent iPhone or iPad can also help you compress files without any extra application installed. This can be achieved through the Files application that includes a native compressor.

Does file compression reduce quality?
The Compress option in Files app uses a data compression method, which is lossless and preserves everything. The Files app will compress your files into zip files. ZIP is a lossless compression format. A Zip file does not reduce the quality of the files it contains. When you extract the files from a Zip file, they should be identical to the original files you zipped.
