Frequently Asked Questions

Does PDF compression reduce quality?

Yes, but the impact depends on your chosen level. "Low" preserves near-original quality, "Medium" is suitable for most documents and emails, and "High" is ideal for web uploads where size matters more than print quality.

What is the maximum file size?

You can upload PDF files up to 50MB. For larger files, consider splitting them into smaller documents first.

Is my PDF file safe and private?

Absolutely. Your file is processed on a secure server with SSL encryption and is automatically deleted within 24 hours. We do not store, read, or share your files.
