Frequently Asked Questions
How much smaller will my PDF be?
Typically 40-90% smaller, depending on the original file and compression level you choose.
Will I lose image quality?
Slight quality loss may occur with high compression. Medium compression offers the best balance of size and quality.
Can I compress an already compressed PDF?
Yes, but you may see diminishing returns. PDFs already optimized may not compress much further.
What makes PDF files so large?
Embedded high-resolution images are the main cause. Compression optimizes these images for smaller size.
Is text affected by compression?
No, text remains perfectly sharp and readable. Only images and graphics are compressed.
