Will compression affect PDF quality?

Low and medium compression maintain excellent quality. High compression may slightly reduce image clarity but text remains sharp and readable.

Is my PDF uploaded to a server?

No! All compression happens in your browser using JavaScript. Your PDF never leaves your device, ensuring complete privacy and security.

What's the maximum file size I can compress?
