Frequently Asked Questions
How does PDF compression work?
Our tool uses multiple techniques including image optimization, font subsetting, color space conversion, and metadata removal to reduce the file size while maintaining document quality.
Is there a file size limit?
Yes, the maximum file size is 100MB due to browser limitations when processing files locally.
Is my PDF safe?
Absolutely. All processing happens directly in your browser. Your PDF files are never uploaded to any server, ensuring complete privacy and security.
What's the difference between compression levels?
Low compression preserves maximum quality with minimal size reduction. Medium offers a balance between quality and size. High compression achieves maximum size reduction with some quality trade-offs. Custom lets you fine-tune specific settings.
Will compression affect my PDF's quality?
The effect on quality depends on the compression level you choose. Low compression has minimal impact, while higher compression may affect image quality. Text remains clear and readable at all compression levels.
