About This Feature

Overview

Reduce File Size is a built-in spreadsheet feature in WPS Office for iOS. It helps reduce file size by optimizing images and removing redundant data, which can improve transfer efficiency and loading speed.

Core tasks include:

  • Automatic analysis of compressible content: after you open the feature, WPS analyzes the spreadsheet and shows content that can be compressed.
  • Optional backup before processing: you can choose to back up the original file before starting the process.
  • Before-and-after size comparison: after processing, you can review the file size change to confirm the result.

This feature is useful for spreadsheets with many images, files that need to be shared more quickly, and large worksheets that take longer to open.

Capability SummaryIn iOS spreadsheets, WPS provides a Reduce File Size entry that analyzes compressible content, lets you back up the original file, and shows a before-and-after size comparison.Microsoft Support explains how to reduce document size by compressing pictures, lowering resolution, deleting cropped areas, and avoiding embedded fonts in desktop Word documents.Google Docs Help explains how to crop images and adjust brightness, transparency, and contrast, but it does not describe a one-tap whole-document file size reduction flow for spreadsheets.Notion Help focuses on uploading, embedding, resizing, and managing images and files, with file size limits that vary by plan.Adobe Acrobat provides PDF size reduction and advanced optimization options, mainly for PDF workflows.
WPS AdvantagesAdvantage: WPS keeps the workflow inside an iOS spreadsheet and combines analysis, optional backup, and result comparison in one flow. Distinct: the result page shows the file size before and after processing.Compared with WPS: Microsoft's official guidance here focuses on desktop document settings and manual picture or font adjustments rather than an in-app iOS spreadsheet slimming flow.Compared with WPS: Google's official page focuses on image editing controls, not automatic spreadsheet analysis with a file size comparison result.Compared with WPS: Notion emphasizes file handling and upload limits rather than automatic spreadsheet file slimming.Compared with WPS: Adobe's official guidance is centered on PDF optimization, so its workflow is aimed at a different file type and use case.

Overall Conclusion
If you need to reduce spreadsheet file size directly on iOS, WPS offers a shorter in-app workflow for that task. Microsoft, Google, Notion, and Adobe each provide official file- or image-related capabilities, but their documented focus is different, such as desktop document settings, image editing, content management, or PDF optimization.
