Frequently asked

Will compression ruin my images?

Recommended mode resamples images to 150 DPI, which still looks sharp on screens and office printers. Pick "Less compression" (300 DPI) for print or "Lossless" to keep every pixel untouched.

What if my PDF is already small?

We compare the result with your original and keep whichever is smaller, so you never get a bigger file back.

Are links and bookmarks kept?

Lossless mode keeps everything. The other levels re-distill the file with Ghostscript, which keeps text, links and bookmarks but may drop interactive form fields.
