Frequently Asked Questions

To compress a PDF for email, simply upload your PDF file to Ozvyn's free PDF compressor tool, adjust the compression slider to "Maximum Compression" (quality level 1-3), and click the compress button. Your PDF will be compressed to a much smaller size, typically reducing it by 70-90%, making it perfect for email attachments while still maintaining readability. You can download the compressed file immediately without registration.

The effect on print quality depends on your compression settings. For print-ready PDFs, use the High Quality setting (7-10), which maintains 300 DPI resolution required for professional printing while still reducing file size by 15-30%. For drafts or internal documents, the Balanced setting (4-6) offers good quality at 175-225 DPI with 40-60% size reduction. Only use Maximum Compression (1-3) for digital sharing where print quality isn't critical.

Ozvyn's PDF compressor processes your files securely on our servers and automatically deletes them after processing. We don't store your PDFs, review their content, or share them with third parties. All compression happens server-side with industry-standard security practices. For highly sensitive documents, you might consider using our downloadable tools for offline compression.

PDF compression specifically targets embedded images and unnecessary metadata while preserving the document's structure, text sharpness, and formatting. Unlike ZIP compression which only packages the file without reducing its actual size, our 300 DPI-optimized compression intelligently reduces the quality of images and graphics to achieve smaller file sizes while keeping text perfectly crisp. This specialized approach results in much smaller files than general compression methods while maintaining readability.
