Can I compress multiple PDFs at once?

Which preset should I use for WhatsApp?

Use the WhatsApp preset. It targets output under 5MB with optimised image quality for mobile screens.

Will compression affect text readability?

The Email and Print presets keep text very readable. WhatsApp preset reduces quality slightly for smaller size. Minimal Loss keeps quality as high as possible.

Is my PDF uploaded to a server?
