Frequently Asked Questions

Will the quality of my PDF change?

Text and vector content remain unchanged. Image-heavy PDFs may see slight quality adjustments to reduce size.

Results vary but many PDFs compress 20-60% without visible quality loss.

Are my files uploaded anywhere?

No. 100% of the compression happens locally in your browser.
