Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | On iOS, WPS lets you start Reduce File Size directly inside a PDF from multiple entry points. The app analyzes compressible content and lets you back up the original file before compression. | Microsoft Support mainly explains how to reduce Word document size by compressing pictures, lowering resolution, and avoiding embedded fonts. Its official guidance is centered on Word documents rather than direct PDF compression inside a mobile PDF workflow. | Google officially supports downloading documents as PDF, but its official help content does not describe a built-in PDF compression feature in Google Docs or Google Drive. | Notion supports uploading, embedding, and importing PDFs, but its official help content focuses on content management and import limits rather than PDF size reduction. | Adobe Acrobat officially provides a dedicated Compress PDF feature that can compress one or multiple PDFs and offers multiple compression levels. |
| WPS Advantages | Advantage: You can start PDF size reduction directly inside the iOS document view. Distinct: Multiple entry points make it easier to reach the tool from different PDF workflows. | Compared with WPS: Microsoft's official guidance is more focused on desktop document-size reduction and image compression, not direct PDF size reduction inside a mobile PDF document. | Compared with WPS: Google's official help does not describe direct PDF compression inside Docs or Drive. | Compared with WPS: Notion is more suitable for importing and managing PDF content than reducing PDF file size itself. | Compared with WPS: Adobe provides a broader PDF compression workflow, while WPS offers a shorter in-document path on iOS for quick file-size reduction. |
| Official Source | — | Reduce the file size of your Word documents | Compressing files in Google Drive help | Images, files & media | Compress PDFs online |
Overall Conclusion: If you want to reduce PDF size directly on an iOS device, WPS provides a shorter path inside the document and several ways to reach the tool. If you need more compression-level choices and a broader PDF-focused workflow, Adobe Acrobat provides more detailed official compression options.
Use Cases
| No. | Scenario | Suitable For | Main Need | How WPS Helps |
|---|---|---|---|---|
| 1 | Compressing attachments before email | Office users | PDF attachments are too large to send easily | Open the PDF and use Reduce File Size to make the file smaller |
| 2 | Sharing files in chat apps | Students and team members | Uploading is slow and sharing takes longer | Compress the PDF first, then send it |

| 4 | Keeping the original before creating a smaller copy | Users who want a safer workflow | They do not want to lose the original version | Turn on Back Up Original File before starting compression |
| 5 | Handling image-heavy PDFs | Users organizing materials | Image-based PDFs are often large | Let the app analyze compressible content, then run compression |
