PDF Size Reducer
Shrink your PDF files to a smaller size. Perfect for email attachments or uploading to websites.
About This Tool
PDF compression reduces file sizes while maintaining document quality. This is essential when facing email attachment limits, storage constraints, or slow upload speeds. Our browser-based compressor optimizes PDF structure without recompressing images, keeping text crisp and graphics clear. The result is typically 10-30% smaller files that look identical to the originals. Unlike cloud-based services, compression happens entirely in your browser. Your financial reports, contracts, and personal documents never leave your device, making this safe for sensitive materials.
