Uploading from your iPhone
The iPhone upload flow follows the same pattern as the web: pick your files, set a title and expiry, and tap Upload. The differences come from how iOS lets you reach your files, through Photos for media or the Files app for everything else.
Picking from Photos
Tap the Upload tab, then tap Photos. iOS shows your photo library including anything stored in iCloud. You can select as many photos and videos as you need. While ZappFiles imports them, you'll see a progress overlay showing how far along it is. The percentage reflects bytes copied across all selected items, so a single 4K video shows steady progress instead of jumping from 0 to 100.
For iCloud-stored items that aren't fully downloaded to your phone yet, importing also pulls them down from iCloud. This can take longer for large videos, but the import progress reflects the actual download, not just a spinner.
Picking from Files
Tap Files instead of Photos when your file lives in iCloud Drive, On My iPhone, Dropbox, Google Drive, or any other cloud provider you have set up. The system file picker opens; navigate to the file you want and tap to select. You can pick multiple files at once.
Files picked this way are referenced through iOS security-scoped bookmarks, so the upload can read from them even if you switch apps or your phone goes to sleep mid-upload.
Title and expiry
The title becomes the heading on your transfer's download page, so make it useful for the recipient. By default, it auto-fills from the first file's name; tap into the title field to change it to something like "Final wedding photos" or "Q3 launch assets".
The expiry slider sets how long the share link stays alive. Free plans default to 14 days; paid plans can extend it up to a year. Once a transfer expires, the files are deleted automatically and the download page shows an "expired" message.
Settings panel
Tap Settings on the upload screen to expand more options: storage region (which controls where the files live for fastest downloads to your recipient), password protection, and delete-after-download. The first two are paid-plan features; if your plan doesn't include them, the controls still appear but show a Pro badge.
Tap Upload
Once you're happy with the setup, tap the Upload button at the bottom. The screen switches to a circular progress ring showing percentage and time remaining. From here, you can put your phone down and walk away. See Background Uploads for what happens next.
