About This Feature

Overview

Document Optimization in WPS Office for iOS helps reduce the size of text documents so they are easier to send, share, and store.

Key capabilities include:

  • Automatically analyzing how much space can be reduced in the current document.
  • Reducing file size by optimizing images and cleaning redundant data.
  • Letting you choose whether to back up the original document before processing.
  • Showing a before-and-after file size comparison after optimization is complete.

This feature is useful for image-heavy documents, files that need to be sent through chat or email, and documents that need to take up less local or cloud storage.

Capability SummaryProvides a Document Optimization entry in the iOS document workflow, automatically analyzes reducible space, and reduces file size by optimizing images and cleaning redundant data.Word desktop documentation explains how to reduce document size by compressing pictures, deleting cropped areas, lowering default resolution, and avoiding embedded fonts.Official Google Docs community content does not describe a built-in way to batch-compress all images inside a document; users are advised to compress images in another app before inserting them.Notion supports uploading, replacing, cropping, and resizing images and other media, but its official help content does not describe a document-wide file size reduction workflow.Acrobat provides PDF compression and optimization tools, including image downsampling, font handling, object cleanup, and user-data cleanup to reduce PDF size.
WPS AdvantagesAdvantage: The feature is available directly in the iOS document workflow. Distinct: You can choose to back up the original document before processing and then review the before-and-after size comparison.Compared with WPS: Microsoft's official guidance here focuses on desktop Word picture compression and document settings rather than an iOS in-document optimization flow.Compared with WPS: Google Docs official public guidance does not show a built-in document-wide optimization tool for this scenario.Compared with WPS: Notion focuses more on content organization and media display than on reducing the size of a text document as a dedicated workflow.Compared with WPS: Adobe's optimization guidance is centered on PDF workflows, while WPS targets text document optimization inside the document workflow itself.

Overall Conclusion: For reducing the size of a text document directly on iOS, WPS keeps the workflow more centralized inside the document experience. Microsoft and Adobe provide more detailed official guidance for desktop document or PDF optimization, while Google Docs and Notion focus on adjacent image or media handling rather than a dedicated document optimization flow.
