FAQ

Will every PDF get smaller?

No. Already optimized PDFs may stay the same size. The kernel avoids returning a larger file.

Does this downsample images?

No. This browser path optimizes PDF object storage. It does not recompress embedded images.

Is the PDF uploaded?

No. Compression runs in the browser with the PDF kernel adapter.
