  • Automatically analyzing compressible content in a presentation.

Capability SummaryOn iOS, you can open a presentation, go to the built-in Reduce File Size entry, let the app analyze compressible content, and choose whether to back up the original file before processing.Microsoft Office provides picture compression to reduce file size, but the official guidance states that these features are available in desktop Office apps rather than Microsoft 365 for the web.Google Slides does not provide an official in-product workflow for compressing individual image file sizes inside Slides; official community guidance points users to resize images outside Slides first.Notion provides image and file upload, display, and size-limit guidance, but it does not provide a built-in presentation file-size reduction workflow.Adobe Acrobat provides Reduced Size PDF and Optimized PDF workflows for reducing PDF file size, with a focus on PDF optimization rather than presentation compression.
WPS AdvantagesAdvantage: You can start file-size reduction directly inside a presentation on iOS. Distinct: You can choose to back up the original file before compression.Compared with WPS: Microsoft's official guidance focuses on desktop picture compression rather than a direct iOS presentation file-size reduction flow.Compared with WPS: Google Slides lacks an official in-app path for compressing image file size directly inside a presentation.Compared with WPS: Notion is centered on content collaboration and file management, not presentation slimming.Compared with WPS: Adobe focuses on PDF optimization, so presentation files usually need a different workflow or conversion first.
