Frequently asked questions
How do I make a PDF smaller for email?
Upload the file, choose a compression level from Low to High, and download the smaller version.
Does compressing a PDF reduce text quality?
Text stays sharp regardless of compression level — compression mainly affects embedded image quality, which is more noticeable at higher settings.
What's the difference between Low and High compression?
Low keeps images closer to original quality with a smaller size reduction; High shrinks the file more aggressively at the cost of more visible image compression.
