Pro Tips for Better Compression
Frequently Asked Questions
How much can I compress my PDF files?
Compression results vary by content type. Light compression typically reduces size by 20%, medium by 40%, and strong by up to 60%. Image-heavy PDFs compress more than text-only documents.
Will compression affect PDF quality?
Our smart compression algorithms are designed to maintain visual quality while reducing file size. Light compression preserves maximum quality, while stronger levels provide smaller files with minimal quality loss.
Is my data secure during compression?
Absolutely! All PDF compression happens entirely in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security of your documents.
What's the maximum file size I can compress?
You can compress PDF files up to 100MB each, with a maximum of 10 files per batch. This ensures optimal performance and prevents browser memory issues.
Can I compress password-protected PDFs?
Currently, password-protected PDFs cannot be compressed. Please remove the password protection first, then compress the file and re-apply security if needed.
Which compression level should I choose?
Choose Light for documents where quality is critical, Medium for general use with balanced size and quality, and Strong for maximum size reduction when quality is less important.
