Can I compress a PDF without losing quality?

Yes. Scanonix optimizes PDF structure on the server without recompressing embedded images, so visual quality stays intact. Size savings vary by how the PDF was built.

Which compression level should I choose?

Light is the gentlest option. Recommended applies stronger structural optimization for most files. Strong adds metadata removal when you need the maximum available reduction.

Will my text become blurry?

No. This tool does not downsample or re-encode page images, so body text and layout stay as in the original PDF.

Are my files uploaded to Scanonix servers?

Yes. Your PDF is uploaded securely and compressed on Scanonix servers. The compressed file is returned for download in your browser.

What should I use after compressing a large merged PDF?

If you combined files first, compress the final PDF. Use Merge PDF or Split PDF when you need to reorganise pages beforehand.
