Frequently Asked Questions
Everything you need to know about compressing PDFs online
Is this PDF compressor really free?
Yes, completely free with no hidden costs, no watermarks, and no sign-up required. Compress unlimited PDFs for personal or business use.
Are my PDF files safe and private?
Absolutely. Files are encrypted during upload and processing, then automatically deleted from our servers within minutes. We never store, view, or share your documents.
What's the difference between standard and maximum compression?
Standard compression balances file size reduction with quality preservation, ideal for most documents. Maximum compression achieves the smallest file size and is best for web publishing or when size is critical.
Will compression reduce PDF quality?
Our compression is designed to minimize quality loss. Standard compression maintains excellent quality. Maximum compression may slightly reduce image quality but text remains perfectly sharp and readable.
How much can I reduce my PDF file size?
Compression results vary based on your PDF content. Image-heavy files typically compress 40-70%, while text-heavy documents may compress 20-40%. You'll see exact savings after compression.
