Frequently Asked Questions
How much can I reduce my PDF file size?
Depending on the content, you can achieve 30-80% file size reduction. PDFs with lots of images see the biggest reductions, while text-heavy PDFs see smaller but still significant improvements.
Will compression affect PDF quality?
Our Balanced setting maintains excellent quality while reducing size. For maximum quality preservation, use Conservative mode. Aggressive mode provides maximum compression with some quality trade-offs.
What compression level should I choose?
Use Balanced (recommended) for most documents. Choose Conservative for important documents where quality is critical. Use Aggressive when file size is the priority.
Can I compress password-protected PDFs?
For security reasons, password-protected PDFs need to be unlocked before compression. Remove the password first, then compress.
Is there a file size limit?
Our free tool supports PDFs up to 50MB. For larger files, consider splitting them first using our PDF Split tool.
