Frequently Asked Questions

How can I verify my files are not uploaded?

Open your browser DevTools (F12), go to the Network tab, and process a file. You will see zero external requests during compression. We encourage you to verify this yourself.

What PDF sizes can I compress?

Free users can compress PDFs up to 10MB. Pro users can process files up to 100MB. There are no limits on compression ratio.

Does compression reduce quality?

Our compressor offers multiple quality levels. You can choose between maximum compression (smaller files, lower quality) or balanced compression (good quality, reasonable size).

Is this HIPAA compliant?

Yes. Since no data is transmitted to any server, there is no risk of PHI (Protected Health Information) exposure. Your files remain on your local device throughout the process.

Can I use this for legal documents?

Absolutely. Many legal professionals use our tool specifically because it ensures client confidentiality. No document ever leaves your device.
