Shrink PDFs for Email
Most email providers limit attachment sizes to 10-25 MB. If your PDF is too large, UnblockPDF's compression tool can reduce it significantly while maintaining readable quality.
Choosing the Right Compression Level
Low compression reduces file size by 10-30% with almost no visible quality change. Perfect for text-heavy documents.
Medium compression offers a good balance between size and quality, typically reducing files by 40-60%.
High compression achieves maximum reduction (60-90%) but may noticeably reduce image quality.
Tips for Smaller PDFs
Before compressing, consider removing unnecessary pages with our Split tool. If your PDF contains high-resolution images that don't need to be print quality, high compression works well for screen viewing.
