Frequently asked questions

How does PDF compression work here?

Embedded raster images are re-encoded at a lower quality. Text-only PDFs may see little change since text is already compact.

Which level should I use?

Balanced suits most files. Use Strong for the smallest size when quality is less critical.

Are my PDFs uploaded?

No. Everything runs in your browser — your document never leaves this device.
