Frequently Asked Questions
How much can I reduce a PDF's size?
Compressing the embedded images typically reduces file size by 30-70% depending on the original content. PDFs with many high-resolution images compress more than text-only documents.
Is the compressed PDF lower quality?
At low and medium compression levels, quality differences are imperceptible. High compression may slightly reduce image resolution.
