Medium and above rasterize pages for maximum reduction. Use Lossless to preserve selectable text.
Government/Job portals often require files of specific sizes (e.g. exactly 10 KB or below 100 KB). If the resulting PDF is larger, we compress it down. If it is smaller, we inject zero-overhead metadata padding to make it **exactly** your targeted KB down to the byte!
