When you want to send a file from your iPhone, you may need to compress it first to reduce its size. This is especially true if you're sending the file via email or another service that has file size limits. You can use the built-in compression feature on your iPhone to zip files together into a smaller package. Here's how:
1. Tap the Files app icon to launch the app.
2. Find the file or files you want to compress in the list of locations on the left side of the screen. You can also tap Browse at the bottom of this list and navigate to the location of your files using iOS' built-in file manager.
3. Tap and hold on one of the selected files until a pop-up menu appears, then select Compress. If you want to compress multiple files at once, make sure they're all selected before tapping Compress.
4. A new compressed ZIP file will appear in your current location with all of your selected files inside it. The original uncompressed versions of these files will remain in their respective locations as well--you don't have to delete them manually after compressing them into a ZIP file.
