Will text become blurry after compression?

No. PDF text and vector elements remain sharp and scalable. Only embedded images are re-compressed based on your chosen preset.

Which compression preset should I choose?

'Recommended' provides the ideal balance of significant size reduction and crisp visual quality for emails and web forms.
