Choose a compression level — high, medium, or low — and pdfs.to runs Ghostscript with downsampling, font subsetting, and duplicate-image detection to shrink your PDF.
If the optimised file ends up larger than the original (rare, but possible for already-compressed PDFs), we return the original instead so you never end up with a bigger file.
