Frequently asked questions

Does compressing a PDF reduce quality?

It depends on the profile you choose. High Quality preserves text sharpness and image detail while still reducing size. Extreme gives the smallest file but may reduce image quality. Recommended is the best starting point for most documents.

What is the maximum PDF size I can compress for free?

Free accounts support PDFs up to 50 MB. Starter: 150 MB. Pro: 500 MB. Business: 2 GB.

Is my PDF safe when uploaded?

Yes. Files are encrypted in transit (TLS), processed in isolated sandboxes, and auto-deleted after 1 hour. We never read or share your file contents.

Why is my PDF still large after compression?

PDFs containing mostly text compress very little — text is already compact data. PDFs with many high-resolution images or embedded fonts compress significantly more.
