FAQ

Is this advanced PDF compression?

No. This is safe client-side compression that rebuilds the PDF and minimizes metadata. It does not aggressively recompress images.

Will every PDF become smaller?

Not always. Some PDFs are already optimized, and LiftPDF will show a clear message when the rebuilt file is not smaller.

Are my PDFs uploaded to a server?

No. Compression runs client-side in your browser with pdf-lib.
