Frequently Asked Questions

How much can I reduce the file size?
Typically 40-80% reduction depending on the PDF content and chosen compression level. PDFs with many images see the best results, while text-only PDFs may see smaller reductions.
Will compression affect the quality of my PDF?
Text and fonts always remain crisp. Low compression maintains near-original image quality. Medium offers a good balance. High compression may slightly reduce image quality for maximum size reduction.
Which compression level should I choose?
For high-quality printing, use Low. For general use and sharing, Medium is recommended. For email attachments and web uploads, use High compression.
Can I compress multiple PDFs at once?
Yes! You can upload and compress up to 10 PDF files simultaneously. Each file will be compressed individually with the same settings.
Is the compression free?
Yes, our PDF compressor is completely free with no hidden costs, no watermarks, and no registration required.
Are my files secure?
Absolutely. We use 256-bit SSL encryption for all transfers. Your files are processed securely and automatically deleted within 1 hour.
Why is my PDF not getting smaller?
Some PDFs are already optimized or contain mostly text, which compresses less. Try a higher compression level, or the PDF may already be at its minimum size.
Can I compress password-protected PDFs?
Password-protected PDFs must be unlocked first. Use our Unlock PDF tool to remove the password, then compress.
