Frequently Asked Questions (FAQs)
Does compressing a PDF reduce quality?
Lossless compression keeps quality intact. Lossy compression slightly reduces image clarity (best for web use).
What's the best compression level?
For printing: High Quality (300 DPI). For emails/web: Recommended or Extreme.
Can I compress scanned PDFs?
Yes! Our tool uses OCR (Optical Character Recognition) to optimize scanned documents.
Why is my PDF still large after compression?
Contains high-resolution images (try Extreme mode) or has embedded fonts (enable font optimization).
Is PDF compression safe?
Absolutely! Our tool uses 256-bit encryption and auto-deletes files after processing.
