About This Feature

Overview

Reduce File Size is a built-in document optimization feature in WPS Office for iOS. It helps reduce the size of text documents for easier sharing, transfer, and storage.

Key capabilities:

  • Document size analysis: automatically checks how much space can be reduced.
  • File size reduction: reduces document size by optimizing images and cleaning redundant data.
  • Original file backup: lets you choose whether to back up the original document before processing.
  • Before-and-after comparison: shows the file size comparison after processing is complete.

Common use cases include sending image-heavy documents, reducing upload friction, and saving storage space on mobile devices.
