Frequently asked questions
Are my PDFs uploaded anywhere?
No. Compression runs entirely in your browser, so your documents never leave your device.
Why didn't my PDF get smaller?
PDFs that contain only text or vector graphics have little to compress, and files that are already optimized may not shrink further. Try Strong for more savings.
Does it affect text?
No. Only embedded photos are re-compressed. Text, fonts and vector graphics are never changed.
