Getting a PDF under a hard size limit
Most compression tools give you a single "compress" button with no control over the outcome. Fitting under a specific limit like 100 KB — common for application forms and portal uploads — usually takes iteration: reduce, check the size, reduce further if needed.
PrivaPDF's quality slider gives you a live size preview as you adjust it, so you can dial in exactly enough compression to clear the 100 KB threshold without over-compressing text-heavy pages into illegibility. Image-heavy PDFs have the most room to shrink; pages that are mostly vector text have a hard floor below which quality loss becomes visible.
