About Compress PDF
Large PDF files can be frustrating to share, upload, and store. AuraPDF's Compress PDF tool reduces your file sizes by up to 90 percent while maintaining the visual quality of your documents. It is the fastest and easiest way to make your PDFs smaller.
Our compression engine intelligently optimizes images, fonts, and document structure to achieve the best possible size reduction. You can choose between three compression levels to match your needs: Low compression for maximum quality, Medium for balanced results, and High for the smallest possible file size.
PDF compression is essential for many common tasks: sending documents via email where attachment sizes are limited, uploading files to websites and portals with size restrictions, reducing storage usage on your device or cloud storage, and improving download speeds when sharing files.
AuraPDF handles all types of PDF content, including images, text, graphics, forms, and mixed-content documents. The compression process is optimized to reduce image sizes where the quality impact is least noticeable while preserving text sharpness and readability.
The tool is completely free with no registration required. No watermarks are added to your compressed files. All processing happens securely in the cloud with 256-bit TLS encryption, and files are automatically deleted within 30 minutes. AuraPDF works on any device and any browser.
