About CompressPDFPro
CompressPDFPro is a free online tool that helps you reduce PDF file sizes quickly and securely. Whether you need to email a large document, save storage space, or meet upload size requirements, our tool makes PDF compression simple and fast.
We use industry-standard Ghostscript technology to compress your PDFs while giving you control over the quality level. Choose from different compression settings based on your needs - from maximum compression for the smallest files to high quality for professional printing.
Your privacy and security are our top priorities. All files are processed securely, automatically deleted after 15 minutes, and removed immediately after download.
Frequently Asked Questions
Is CompressPDFPro really free?
Yes! Our basic service is completely free with no hidden costs. You can compress PDFs up to 10MB in size with access to all quality settings. We also offer a Pro version for users who need batch processing and larger file sizes.
Is my data safe?
Absolutely. We take security seriously. All uploads use HTTPS encryption, files are automatically deleted after 15 minutes, and are removed immediately after you download them. We never read, analyze, or share your file contents.
Which compression quality should I choose?
Recommended (150 DPI): Best for most uses - good balance between file size and quality.
High Quality (300 DPI): Use when you need to print the document or preserve maximum quality.
Smaller File (72 DPI): Maximum compression - use when file size matters more than quality. Note: May make text harder to read.
What's the maximum file size I can upload?
Free users can compress PDFs up to 10MB. Need larger files? Check out our Pro version for files up to 100MB and batch processing capabilities.
How does PDF compression work?
We use Ghostscript, a powerful open-source tool, to optimize your PDFs. It works by reducing image resolution, removing duplicate data, and optimizing the PDF structure - all while maintaining readability.
Will compression affect my PDF quality?
It depends on the quality setting you choose. The "Recommended" setting provides good compression while keeping text sharp and images clear. "High Quality" preserves maximum quality with less compression. Always preview your compressed PDF to ensure it meets your needs.
Can I compress password-protected PDFs?
Currently, our service doesn't support password-protected PDFs. You'll need to remove the password protection before compressing. This feature may be added in a future update.
Do you keep my files?
No. Files are automatically deleted after 15 minutes and are also removed immediately after you download them. We don't store, analyze, or share your files with anyone.
