Starting in mid-2025, Microsoft has rolled out a significant update to its popular cloud storage platforms, OneDrive and SharePoint. According to a recent video by Ami Diamond [MVP], users can now directly compress PDF files within the web interfaces of these services. This new feature eliminates the need for third-party software or additional downloads, marking a notable improvement in how documents are managed and shared across Microsoft 365 environments.
The newly introduced PDF compression tool allows users to reduce the size of PDF documents up to 300 MB in just a few clicks. When viewing a PDF in OneDrive or SharePoint, users will notice a new menu option labeled “Compress.” From there, they can choose between three levels of compression: Light Compress, Medium Compress, and Heavy Compress. This flexibility lets users decide how much they want to shrink their files while considering the importance of maintaining document quality.
By offering multiple compression levels, Microsoft acknowledges the tradeoff between file size and visual fidelity. A lighter compression may retain more detail but result in a larger file, while heavier compression achieves greater reduction but may compromise some document clarity. Therefore, users are empowered to choose what best fits their specific needs, whether that’s archiving, sharing, or collaborative editing.
One of the most compelling aspects of this update is its seamless integration into the existing Microsoft 365 workflow. Previously, users had to download large PDFs, run them through external compression tools, and then re-upload them—a process that was both time-consuming and cumbersome. Now, with compression available directly in the cloud, the workflow is greatly simplified. Users can compress and share documents without ever leaving the OneDrive or SharePoint environment.
Furthermore, the feature is enabled by default, requiring no administrative setup. This ensures that organizations of all sizes can benefit from enhanced storage management and faster document sharing right out of the box. As a result, collaboration becomes smoother, and teams can focus more on their work and less on file logistics.
While the convenience of built-in compression is clear, it also brings up important considerations regarding document quality and storage efficiency. The ability to select a compression level means users must assess their priorities: Is it more important to preserve high-resolution graphics, or is minimizing storage usage the main goal? For example, departments handling legal or design documents might opt for lighter compression, while those prioritizing fast sharing or archiving could choose heavier compression.
Additionally, the support for PDFs up to 300 MB addresses the challenge of managing very large documents, a common pain point for enterprises. By reducing file sizes, organizations can save on storage costs and speed up downloads, but they must also ensure that essential information remains legible after compression.
Microsoft has planned a phased rollout for this feature. According to the video, targeted release began in early July 2025, with general availability expected by early August 2025. This staged approach allows Microsoft to gather feedback and ensure a smooth transition for all users.
In conclusion, the addition of native PDF compression in OneDrive and SharePoint not only streamlines document management but also supports Microsoft’s broader commitment to enhancing productivity and collaboration within the cloud. By balancing quality and efficiency, this feature promises to make everyday workflows faster and more adaptable for users across industries.
